<div class="sectionbody">
<div class="paragraph"><p>Lorsqu&#8217;il est ouvert depuis <em>Subsurface</em>, ce manuel n&#8217;a pas de contrôles
externes. Cependant, une fonction de <em>RECHERCHE</em> est importante. Elle est
activée par la combinaison de touches du clavier Ctrl-F ou commande-F. Un
champ de recherche apparait en bas de la fenêtre. Il suffit de l&#8217;utiliser
pour rechercher n&#8217;importe quel terme dans le manuel.</p></div>

<div class="sect1">
<h2 id="_le_sondage_utilisateur">2. Le sondage utilisateur</h2>
<div class="sectionbody">
<div class="paragraph"><p>Dans le but de développer <em>Subsurface</em> d&#8217;une manière qui serve ses
utilisateurs de la meilleur manière qu&#8217;il soit, il est important d&#8217;avoir des
informations sur les utilisateurs. À l&#8217;ouverture de <em>Subsurface</em> après avoir
utilisé le logiciel pendant une semaine environ, une fenêtre de sondage
apparait. Cela est complètement optionnel et l&#8217;utilisateur contrôle quelles
informations sont envoyées ou non à l'équipe de développement de
<em>Subsurface</em>. Toutes les données que l&#8217;utilisateur choisit d&#8217;envoyer sont
extrêmement utiles et ne seront utilisées que pour les futures
développements et modifications du logiciel pour coller au mieux aux besoins
des utilisateurs de <em>Subsurface</em>. Si vous complétez le sondage ou cliquez
sur l&#8217;option pour ne plus être sondé, cela devrait être la dernière
communication de ce type que vous recevrez. Cependant, si vos habitudes de
plongées ou d&#8217;utilisation de Subsurface changent, vous pouvez envoyer un
nouveau sondage en démarrant <em>Subsurface</em> avec l&#8217;option  <em>--survey</em> sur la
ligne de commande.</p></div>
</div>
</div>
<div class="sect1">
<h2 id="S_StartUsing">3. Commencer à utiliser le programme</h2>
<div class="sectionbody">
<div class="paragraph"><p>La fenêtre <em>Subsurface</em> est généralement divisée en 4 panneaux avec un <strong>Menu
principal</strong> (Fichier Importer Journal Vue Aide) en haut de la fenêtre (pour
Windows et Linux) ou en haut de l'écran (pour Mac et Ubuntu Unity). Les
quatre panneaux sont :</p></div>
<div class="paragraph"><p>La <strong>liste des plongées</strong> en bas à gauche, contenant une liste de toutes les
plongées du journal (carnet) de plongées de l&#8217;utilisateur. Une plongée peut
être sélectionnée et mise en surbrillance dans la liste en cliquant
dessus. Dans la plupart des cas, les touches haut/bas peuvent être utilisée
pour passer d&#8217;une plongée à l&#8217;autre. La <strong>liste des plongées</strong> est un outil
important pour manipuler un journal (carnet) de plongée.</p></div>
<div class="paragraph"><p>La <strong>carte de plongée</strong> en bas à droite, affiche les sites de plongées de
l&#8217;utilisateur, sur une carte mondiale et centrée sur le site de la dernière
plongée sélectionnée dans la <strong>liste des plongées</strong>.</p></div>
<div class="paragraph"><p>Les <strong>informations</strong> en haut à gauche, fournissent des informations détaillées
sur la plongée sélectionnée dans la <strong>liste des plongées</strong>, dont des
statistiques pour la plongée sélectionnée ou pour toutes les plongées mises
en surbrillance.</p></div>
<div class="paragraph"><p>Le <strong>profil de plongée</strong> en haut à droite, affiche un profil de plongée
graphique de la plongée sélectionnée dans la <strong>liste des plongées</strong>.</p></div>
<div class="paragraph"><p>Les séparateurs entre ces panneaux peuvent être déplacés pour modifier la
taille de chaque panneau. <em>Subsurface</em> mémorise la position de ces
séparateurs, pour qu&#8217;au prochain lancement <em>Subsurface</em> utilise ces
positions.</p></div>
<div class="paragraph"><p>Si une plongée est sélectionnée dans la <strong>liste des plongées</strong>, l&#8217;emplacement
de la plongée, les informations détaillées et le profil de la <em>plongée
sélectionnée</em> sont affichées dans les panneaux respectifs. D&#8217;autre part, si
plus d&#8217;une plongée est mise en surbrillance seule la dernière mise en
surbrillance est la <em>plongée sélectionnée</em>, mais les données de <em>toutes les
plongées mises en surbrillances</em> sont affichées dans l&#8217;onglet <strong>Stats</strong> du
panneau <strong>informations</strong> (profondeur maximale, minimale et moyenne, les
durées, les températures de l&#8217;eau et le SAC (air consommé); temps total et
nombre de plongées sélectionnées).</p></div>
<div class="imageblock" id="S_ViewPanels" style="text-align:center;">
<div class="content">
<img src="images/main_window_f20.jpg" alt="The Main Window" />
</div>
</div>
<div class="paragraph"><p>L&#8217;utilisateur peut déterminer si lesquels des quatre panneaux sont affichés
en sélectionnant l&#8217;option <strong>Vue</strong> dans le menu principal. Cette fonctionnalité
permet plusieurs choix d&#8217;affichage :</p></div>
<div class="paragraph"><p><strong>Tout</strong> : affiche les quatre panneaux tels que sur la capture d'écran ci-dessus.</p></div>
<div class="paragraph"><p><strong>Liste des plongées</strong> : affiche uniquement la liste des plongées.</p></div>
<div class="paragraph"><p><strong>Profil</strong> : affiche uniquement le profile de plongée de la plongée sélectionnée.</p></div>
<div class="paragraph"><p><strong>Info</strong> : affiche uniquement les notes de plongées de la dernière plongée sélectionnée et les statistiques pour
toutes les plongées mises en surbrillance.</p></div>
<div class="paragraph"><p><strong>Globe</strong> : affiche uniquement la carte mondiale, centrée sur la dernière plongée sélectionnée.</p></div>
<div class="paragraph"><p>Comme la plupart des autre fonctions qui peuvent être accédée via le menu
principal, ces options peuvent être utilisées par des raccourcis
clavier. Les raccourcis pour un système particulier sont affichés avec un
souligné des les entrées de menu. À cause des différents systèmes
d&#8217;exploitation et des divers langues, <em>Subsurface</em> peut utiliser différentes
touches de raccourcis et ne sont donc pas détaillées ici.</p></div>
<div class="paragraph"><p>Lorsque le programme est lancé pour la première fois, il n&#8217;affiche aucune
information. Ceci parce que le programme n&#8217;a aucune information de plongée
disponible. Dans les sections suivantes, le procédure pour créer a nouveau
carnet de plongée sera détaillée.</p></div>
</div>
</div>
<div class="sect1">
<h2 id="S_NewLogbook">4. Créer un nouveau carnet de plongée</h2>
<div class="sectionbody">
<div class="paragraph"><p>Sélectionner <em>Fichier &#8594; Nouveau carnet de plongée</em> à partir du menu
principal. Toutes les données de plongées sont effacées pour que de

<h3 id="S_EnterData">5.1. Entrer les informations de plongée à la main</h3>
<div class="paragraph"><p>This is usually the approach for dives without a dive computer. The basic
record of information within <em>Subsurface</em> is a dive. The most important
information in a simple dive logbook usually includes dive type, date, time,
duration, depth, the names of your dive buddy and of the dive master or dive
guide, and some remarks about the dive. <em>Subsurface</em> can store much more
information than this for each dive. In order to add a dive to a dive log,
select <em>Log &#8594; Add Dive</em> from the Main Menu. The program then shows three
panels to enter information for a dive: two tabs in the <strong>Info</strong> panel
(<strong>Notes</strong> and <strong>Equipment</strong>), as well as the <strong>Dive Profile</strong> panel that displays
a graphical profile of each dive. These panels are respectively marked
<span class="red">A</span>, <span class="red">B</span> and <span class="red">C</span> in the figure below. Each of these tabs will
now be explained for data entry.</p></div>
<div class="imageblock" style="text-align:center;">
<div class="content">
<img src="images/AddDive1_f20.jpg" alt="FIGURE: Add dive" />
</div>
</div>
<div class="paragraph"><p>When one edits a field in Notes or Equipment panels, <em>Subsurface</em> enters
<strong>Editing Mode</strong>, indicated by the message in the blue box at the top of the
<em>Notes</em> panel (see the image below). This message is displayed in all the
panels under Notes and Equipment when in <strong>Editing Mode</strong>.</p></div>
<div class="imageblock" style="text-align:center;">
<div class="content">
<img src="images/BlueEditBar_f20.jpg" alt="Blue edit bar" />
</div>
</div>
<div class="paragraph"><p>The <em>Save</em> button should only be selected after all the parts of a dive have
been entered.  When entering dives by hand, the <em>Info</em>, <em>Equipment</em> and
<em>Profile</em> tabs should be completed before saving the information. By
selecting the <em>Save</em> button, a local copy of the information for this
specific dive is saved in memory. When one closes Subsurface, the program
will ask again, this time whether the complete dive log should be saved on
disk or not.</p></div>
<div class="sect3">
<h4 id="_notes">5.1.1. Notes</h4>
<div class="paragraph"><p>This panel contains the date, time and place information for a particular
dive, environmental conditions, co-divers and buddies, as well as some
descriptive information. If one clicks on the <strong>Notes</strong> tab, the following
fields are visible:</p></div>
<div class="imageblock" style="text-align:center;">
<div class="content">
<img src="images/AddDive2_f20.jpg" alt="FIGURE: The Notes tab" />
</div>
</div>
<div class="paragraph"><p>The <strong>Time</strong> field reflects the date and the time of the dive. By clicking the
date, a calendar is displayed from which one can choose the correct
date. Press ESC to escape from the calendar.  The time values (hour and
minutes) can also be edited directly by clicking on each of them in the text
box and by overtyping the information displayed. The default date is the
present date and the default time is an hour in advance of the present time.</p></div>
<div class="paragraph"><p><strong>Air and water temperatures</strong>: the air and water temperatures during the
dive can be typed directly on the fields to the right of the Start time.
Temperature units are not needed, as they will be automatically supplied by
<em>Subsurface</em>. Only the numerical value must be
typed by the user (the units selected in the <em>Preferences</em>
will determine whether metric or imperial units are used).</p></div>
<div class="paragraph"><p><strong>Location</strong>: Here the name of the dive site can be entered, e.g. "Tihany, Lake
Balaton,
Hungary". Auto completion of location names will make this easier if one
frequently dives at the same sites.</p></div>
<div class="paragraph"><p><strong>Coordinates</strong>: The geographic coordinates of the dive site should be entered
here. These can come from three sources:</p></div>
<div class="olist loweralpha"><ol class="loweralpha">
<li>
<p>
One can find the coordinates on the world map in the bottom right hand part
   of the Subsurface window. The map displays a green bar indicating "No
   location data - Move the map and double-click to set the dive
   location". Upon a double-click at the appropriate place, the green bar
   disappears and the coordinates are stored.
</p>
</li>
<li>
<p>
The coordinates can be obtained from the <em>Subsurface</em> Companion app if the
   user has an Android or iPhone device with GPS and if the coordinates of the
   dive site were stored using that device.  <a href="#S_Companion">Click here for
   more information</a>
</p>
</li>
<li>
<p>
The coordinates can be entered by hand if they are known, using one of four
   formats with latitude followed by longitude:
</p>
<div class="literalblock">
<div class="content">
<pre><code>ISO 6709 Annex D format e.g. 30°13'28.9"N 30°49'1.5"E Degrees and decimal
minutes, e.g. N30° 13.49760' , E30° 49.30788' Degrees minutes seconds,
e.g. N30° 13' 29.8" , E30° 49' 1.5" Decimal degrees, e.g. 30.22496 ,
30.821798</code></pre>
</div></div>
</li>
</ol></div>
<div class="paragraph"><p>Southern hemisphere latitudes are given with a <strong>S</strong>, e.g. S30°, or with a
negative value, e.g. -30.22496. Similarly western longitudes are given with
a <strong>W</strong>, e.g. W07°, or with a negative value, e.g. -7.34323.</p></div>
<div class="paragraph"><p>Some keyboards don&#8217;t have the degree sign (°). It can be replaced by a d
like that: N30d W20d.</p></div>
<div class="paragraph"><p>Please note that GPS coordinates of a dive site are linked to the Location
name - so adding coordinates to dives that do not have a location
description will cause unexpected behaviour (Subsurface will think that all
of these dives have the same location and try to keep their GPS coordinates
the same).</p></div>
<div class="paragraph"><p><strong>Dive mode</strong>: This is a dropdown box allowing one to choose the type of dive
performed. The options are OC (Open Circuit, the default setting, meant for most recreational dives),
Freedive (dive without SCUBA equipment), CCR (Closed-circuit
rebreather) and pSCR (Passive semi-closed rebreather).</p></div>
<div class="paragraph"><p><strong>Divemaster</strong>: The name of the dive master or dive guide for this dive can be
entered here.
Again, this field offers auto completion based on the list of dive masters in
the current logbook.</p></div>
<div class="paragraph"><p><strong>Buddy</strong>: In this field one can enter the name(s) of the buddy / buddies
(separated by commas) who accompanied the user on the dive. Auto completion
is offered based on the list of buddies in the current logbook.</p></div>
<div class="paragraph"><p><strong>Suit</strong>: The type of diving suit used for the dive can be entered here.
As with the other items, auto completion of the suit description is available.
Some dry-suit users may choose to use this field to record what combination of
suit and thermal protection undersuit was used.</p></div>

<div class="paragraph"><p>The Equipment tab allows the user to enter information about the type of
cylinder and gas used, as well as the weights used for a dive. This is a
highly interactive part of <em>Subsurface</em> and the information on cylinders and
gases (entered here) affects the behaviour of the dive profile (top

<div class="paragraph"><p>The + button at the top right allows the user to add more cylinders for this
dive.  The dark dustbin icon on the left allows one to delete information
for a particular cylinder. Note that it is not possible to delete a cylinder
if it is used during the dive. One cylinder is implicitly used in the dive,
even without a gas change event. Thus the first cylinder cannot be deleted
until another cylinder is created.</p></div>
<div class="paragraph"><p>Start by selecting a cylinder type on the left-hand side of the table.  To
select a cylinder, click in the <strong>Type</strong> box.  This brings up a button that

</div>
<div class="paragraph"><p>The drop-down list can be used to select the cylinder type used for the dive
or the user may start typing in the box which shows the available options
for the entered characters. The <strong>Size</strong> of the cylinder as well as its
working pressure (<strong>WorkPress</strong>) will automatically be shown in the
dialogue. If a cylinder is not shown in the dropdown list, type the name and
description of that cylinder into the <strong>Type</strong> field.</p></div>
<div class="paragraph"><p>Next, indicate the starting pressure and the ending pressure of the gas used
during the dive. The unit of pressure (metric/imperial) corresponds to the
setting in the <em>Preferences</em>.</p></div>
<div class="paragraph"><p>Finally, type in the gas mixture used in the <strong>O2%</strong> field. If air was used, a
value of 21% can be entered on this field, or it might be left blank. If
nitrox or trimix were used, their percentages of oxygen and/or helium must
be specified.  Any inappropriate fields should be left empty. After typing
the information for the cylinder, press <em>ENTER</em> on the keyboard or click
outside the cell that contains the cursor. Information for any additional
cylinders can be added by using the + button at the top right

</div>
<div class="paragraph"><p><em>Modifying the dive profile</em>: When the cursor is moved around the dive
profile, its position is indicated by two coloured lines (red and green) as
shown below.  The depth and time that the cursor represents are indicated at
the top of the black information box (@ and D). The units (metric/imperial)
on the axes are determined by the <strong>Preference</strong> settings. The dive profile
itself comprises several line segments demarcated by waypoints (white dots
on the profile, as shown above). The default dive depth is 15 m.  If the
dive depth was 20 m then the user needs to drag the appropriate waypoints
downwards to represent 20 m. To add a waypoint, double-click on any line
segment. To move an additional waypoint, drag it.  To remove this waypoint,
right-click on it and choose "Remove this point" from the context menu. The
user needs to drag the waypoints to represent an accurate time duration for
the dive. Below is a dive profile that represents a dive to 20 m for 30 min,

<div class="paragraph"><p>To import dive information from a dive computer to a computer with
<em>Subsurface</em>, it is necessary that the two pieces of equipment communicate
with one another.  This involves setting up the communications port (or
mount point) of the computer with <em>Subsurface</em> that communicates with the
dive computer. In order to set up this communication, one needs to find the
appropriate information to instruct <em>Subsurface</em> where and how to import the
dive information.
<a href="#_appendix_a_operating_system_specific_information_for_importing_dive_information_from_a_dive_computer">Appendix

different operating systems and
<a href="#_appendix_b_dive_computer_specific_information_for_importing_dive_information">Appendix

<div class="paragraph"><p>After this, the dive computer can be hooked up to the user&#8217;s PC, which can
be achieved by following these steps:</p></div>
<div class="olist arabic"><ol class="arabic">
<li>
<p>
The interface cable should be connected to a free USB port (or the Infra-red
        or Bluetooth connection set up as described later in this manual)
</p>
</li>
<li>
<p>
The dive computer should be placed into PC Communication mode.
        (Users should refer to the manual of their specific dive computer)
</p>
</li>
<li>
<p>
In <em>Subsurface</em>, from the Main Menu, the user must select <em>Import &#8594; Import
   From Dive Computer</em>.  Dialogue <strong>A</strong> in the figure below appears:

</ol></div>
<div class="imageblock" style="text-align:center;">
<div class="content">
<img src="images/DC_import_f20.jpg" alt="FIGURE: Download dialogue 1" />
</div>
</div>
<div class="paragraph"><p>Dive computers tend to keep a certain number of dives in their memory, even
though these dives have already been imported to <em>Subsurface</em>. For that
reason, if the divecomputer allows this, <em>Subsurface</em> only imports dives
that have not been uploaded before. This makes the download process faster
on most dive computers and also saves battery power of the dive computer (at
least for those not charging while connected via USB).  If, for some reason,
the user wishes to import ALL dives from the dive computer, even though some
may already be in the logbook, then check the check box labeled <em>Force
download of all dives</em>.</p></div>
<div class="ulist"><ul>
<li>
<p>
The dialogue has two drop-down lists, <strong>Vendor</strong> and <strong>Dive Computer</strong>. On the
   <strong>vendor</strong> drop-down list select the make of the computer, e.g.  Suunto,
   Oceanic, Uwatec, Mares. On the <strong>Dive Computer</strong> drop-down list, the model
   name of the dive computer must be selected, e.g. D4 (Suunto), Veo200
   (Oceanic), or Puck (Mares).
</p>
</li>
<li>
<p>
The <strong>Device or Mount Point</strong> drop-down list contains the USB or Bluetooth
   port name that <em>Subsurface</em> needs in order to communicate with the dive
   computer.  The appropriate port name must be selected. Consult
   <a href="#_appendix_a_operating_system_specific_information_for_importing_dive_information_from_a_dive_computer">Appendix
   A</a> and
   <a href="#_appendix_b_dive_computer_specific_information_for_importing_dive_information">Appendix
   B</a> for technical details on how to find the appropriate port information for
   a particular dive computer and, in some cases, how to do the correct
   settings to the operating system of the computer on which <em>Subsurface</em> is
   running.
</p>
</li>
<li>
<p>
If all the dives on the dive computer need to be downloaded, check the
   checkbox <em>Force download of all dives</em>. Normally, <em>Subsurface</em> only
   downloads dives after the date-time of the last dive in the <strong>Dive List</strong>
   panel. If one or more of your dives in <em>Subsurface</em> have been accidentally
   deleted or if there are older dives that still need to be downloaded from
   the dive computer, this checkbox needs to be activated. Some dive computers
   (e.g. Mares Puck) do not provide a contents list to <em>Subsurface</em> before the
   download in order to select only new dives.  Consequently, for these dive
   computers, all dives are downloaded irrespective of the status of this check
   box.
</p>
</li>
<li>
<p>
If the checkbox <em>Always prefer downloaded dives</em> has been checked and,
   during download, dives with identical date-times exist on the dive computer
   and on the <em>Subsurface</em> <strong>Dive List</strong> panel, the dive in the <em>Subsurface</em>
   divelog will be overwritten by the dive record from the dive computer
</p>
</li>
<li>
<p>
The checkbox marked <em>Download into new trip</em> ensures that, after upload, the
   downloaded dives are grouped together as a new trip(s) in the <strong>Dive List</strong>.
</p>
</li>
<li>
<p>
Do <strong>not</strong> check the checkboxes labelled <em>Save libdivecomputer logfile</em> and
   <em>Save libdivecomputer dumpfile</em>. These are only used as diagnostic tools
   when problems with downloads are experienced (see below).
</p>
</li>
<li>
<p>
Then select the <em>Download</em> button. After successful download, Dialogue <strong>B</strong>
   in the figure above appears.
</p>
</li>
<li>
<p>
With communication established, one can see how the data are retrieved from
   the dive computer.  Depending on the make of the dive computer and/or number
   of recorded dives, this could take some time. Be patient. The <em>Download</em>
   dialogue shows a progress bar at the bottom of the dialogue (for some dive
   computers the progress information could be inaccurate as we cannot
   determine how much downloadable data there is until all data have been
   downloaded). When the download of the dive information is complete, all the
   imported dives appear in the <strong>Dive List</strong>, sorted by date and
   time. Disconnect and switch off the dive computer to conserve its battery
   power.  If a particular dive is selected, the <strong>Dive Profile</strong> panel shows an
   informative graph of dive depth against time for that particular dive.
</p>
</li>
</ul></div>
<div class="paragraph"><p>After the dives have been downloaded, they appear in a tabular format on the
righthand side of the dialogue (see image <strong>B</strong>, above). Each dive comprises a
row in the table, with the date, duration and depth shown. Next to each dive
is a checkbox: check all the dives that need to be transfered to the <strong>Dive
List</strong>. In the case of the image above, the last six dives are checked and
will be transfered to the <strong>Dive List</strong>.</p></div>

<h4 id="S_DeviceNames">5.2.2. Changing the name of a dive computer</h4>
<div class="paragraph"><p>It may be necessary to distinguish between different dive computers used to
upload dive logs to <em>Subsurface</em>. For instance if one&#8217;s partner&#8217;s dive
computer is the same make and model as one&#8217;s own and dive logs are uploaded
from both dive computers to the same <em>Subsurface</em> computer, then one would
perhaps like to call one dc "Alice&#8217;s Suunto D4" and the other one "Bob&#8217;s
Suunto D4". Alternatively, perhaps a technical diver dives with two or more
dive computers of the same model, the logs of both (or all) being uploaded.
In this case it might be prudent to call one of them "Suunto D4 (1)" and
another one "Suunto D4 (2)". This is easily done in <em>Subsurface</em>.  On the
<strong>Main Menu</strong>, select <em>Log &#8594; Edit device names</em>. A dialog opens, indicating
the current Model, ID and Nickname of the dive computers used for
upload. Edit the Nickname field for the appropriate dive computer. After
saving the Nickname, the dive logs show the nickname for that particular
device instead of the model name, allowing easy identification of devices.</p></div>

<div class="paragraph"><p>The date and time of the dive, gas mixture and (often) water temperature are
usually shown as obtained from the dive computer, but the user needs to add
additional information by hand in order to have a more complete dive
record. In a few cases, (e.g. APD rebreathers) one also has to provide the
date and time of the dive.  If the contents of this tab is changed or edited
in any way, the message in a blue box at the top of the panel indicates that
the dive is being edited. If one clicks on the <strong>Notes</strong> tab, the following

date, a calendar is displayed from which one can choose the correct
date. Press ESC to close the calendar.  The time values (hour and minutes)
can also be edited directly by clicking on each of them in the text box and
by overtyping the information displayed.</p></div>
<div class="paragraph"><p><strong>Air/water temperatures</strong>: Air and water temperatures during the dive are shown
in these fields to the right of the Start time. Many dive computers supply water
temperature information and this field may therefore contain information obtained from the dive computer.
If air temperature is not provided by the dive computer, the first temperature reading
might be used for the air temperature. Generally this is close enough to the real air temperature as
the change in the temperature sensor reading is quite slow to follow the changes in the environment.
If editing is required, only a value is required, the units of temperature will be
automatically supplied by
<em>Subsurface</em> (according to the <em>Preferences</em>, metric or imperial units will
be used).</p></div>
<div class="paragraph"><p><strong>Location</strong>: In this field one should type in text that describes the site
where the dive was performed, e.g. "Tihany, Lake Balaton, Hungary".
Auto completion of location names will
make this easier if one frequently dives at the same sites.</p></div>

<div class="paragraph"><p><strong>Tags</strong>: Tags that describe the type of dive performed can be entered
here (separated by commas). Examples of common tags are boat, drift, training,
cave, etc.
<em>Subsurface</em> has many built-in tags. If the user starts typing a tag, the

dive. The dark dustbin icon on the left allows the deletion of information
for a cylinder.  Note that it is not possible to delete a cylinder if it is
used during the dive. A cylinder might be implicitly used in the dive, even
without a gas change event.</p></div>
<div class="paragraph"><p>The user should start by selecting a cylinder type on the left-hand side of

be entered or this field can be left blank. If nitrox or trimix were used,
their percentages of oxygen and/or helium should be entered.  Any
inappropriate fields should be left empty. After typing the information for
the cylinder, either press <em>ENTER</em> on the keyboard or click outside the cell

<h4 id="_editing_several_selected_dives_simultaneously">5.2.6. Editing several selected dives simultaneously</h4>
<div class="paragraph"><p><em>METHOD 1</em>: After uploading dives from a dive computer, the dive profiles of
the uploaded dives are shown in the <strong>Dive profile</strong> tab, as well as a few
items of information in the <strong>Notes</strong> tab (e.g. water temperature) and in the
<strong>Equipment</strong> tab (e.g. gas pressures and gas composition). However the other
fields remain empty.  It may be useful to simultaneously edit some of the
fields in the <strong>Notes</strong> and <strong>Equipment</strong> tabs.  For instance, it is possible
that a diver performed several dives during a single day, using identical
equipment while diving at the same dive site or with the same dive master
and/or buddy or tags. Instead of completing the information for each of
these dives separately, one can select all the dives for that day in the
<strong>Dive List</strong> and insert the same information in the <strong>Notes</strong> and <strong>Equipment</strong>
fields that need identical information. This is achieved by editing the dive
notes or the equipment for any one of the selected dives.</p></div>
<div class="paragraph"><p>The simultaneous editing only works with fields that do not already contain
information.  This means that, if some fields have been edited for a
particular dive among the selected dives, these are not changed while
editing the dives simultaneously. Technically, the rule for editing several
dives simultaneously is: if the data field being edited contains <em>exactly
the same information</em> for all the dives that have been selected, the new,
edited information is substituted for all the selected dives, otherwise only
the edited dive is changed, even though several dives have been selected in
the <strong>Dive List</strong>. This greatly speeds up the completion of the dive log after
several similar dives.</p></div>
<div class="paragraph" id="S_CopyComponents"><p><em>METHOD 2</em>:There is a different way of achieving the same goal. Select a
dive with all the appropriate information typed into the <strong>Notes</strong> and
<strong>Equipment</strong> tabs. Then, from the main menu, select <em>Log &#8594; Copy dive
components</em>.  A box is presented with a selection of check boxes for most of
the fields in the <strong>Notes</strong> and <strong>Equipment</strong> tabs.  Select the fields to be
copied from the currently selected dive, then select <em>OK</em>. Now, in the <strong>Dive
List</strong>, select the dives into which this information is to be pasted. Then,
from the main menu, select <em>Log &#8594; Paste dive components</em>.  All the selected

<div class="paragraph" id="S_ImportingAlienDiveLogs"><p>If a user has been diving for some time, it is possible that several dives
were logged using other dive log software. This information does not need
retyping because these dive logs can probably be imported into
<em>Subsurface</em>. <em>Subsurface</em> will import dive logs from a range of other dive
log software. While some software is supported natively, for others the user
has to export the logbook(s) to an intermediate format so that they can then
be imported by <em>Subsurface</em>.  Currently, <em>Subsurface</em> supports importing CSV
log files from several sources.  APD LogViewer, XP5, Sensus and Seabear
files are preconfigured, but because the import is flexible, users can
configure their own imports.  Manually kept log files (e.g. in spreadsheet)
can also be imported by configuring the CSV import.  <em>Subsurface</em> can also
import UDDF and UDCF files used by some divelog software and some dive
computers, like the Heinrichs &amp; Weikamp DR5. Finally, for some divelog
software like Mares Dive Organiser it is currently suggested to import the
logbooks first into a webservice like <em>divelogs.de</em> and then import them
from there with <em>Subsurface</em>, as divelogs.de supports a few additional
logbook formats that <em>Subsurface</em> currently cannot parse.</p></div>
<div class="paragraph"><p>If the format of other software is supported natively on Subsurface, it
should be sufficient to select either <em>Import &#8594; Import log files</em> or <em>File
&#8594; Open log file</em>. <em>Subsurface</em> supports the data formats of many dive
computers, including Suunto and Shearwater. When importing dives,
<em>Subsurface</em> tries to detect multiple records for the same dive and merges
the information as best as it can. If there are no time zone issues (or
other reasons that would cause the beginning time of the dives to be
significantly different) <em>Subsurface</em> will not create duplicate entries.</p></div>

organised into a single line that provides the headers (or <em>field names</em> or
<em>column headings</em>) of the data columns, followed by the data, one record per
line.</p></div>
<div class="paragraph"><p>There are two types of <em>CSV</em> dive logs that can be imported into
<em>Subsurface</em>:</p></div>
<div class="olist arabic"><ol class="arabic">
<li>
<p>
<em>CSV dive details</em>: This dive log format contains similar information to
   that of a typical written dive log, e.g. dive date and time, dive depth,
   dive duration, names of buddy and dive master and perhaps some information
   about cylinder pressures before and after the dive, as well as a comment or
   two about the dive. All the data for a single dive go on a single line of
   text, following the order of the column headings.
</p>
</li>
<li>
<p>
<em>CSV dive profile</em>: This dive log format includes much more information
   about a single dive. For instance there may be information at 30-second
   intervals, indicating depth, water temperature at that depth, and cylinder
   pressure at that moment in time. Each line contains the information for a
   single instant in time during the dive, 30 seconds after that of the
   previous instant. Many lines are required to complete the depth profile
   information for a single dive. This is a common export format used by
   closed-circuit rebreather (CCR) dive equipment and many software packages
   that handle dive computer data and/or dive logs.
</p>
</li>
</ol></div>
<div class="paragraph"><p>Before being able to import the <em>CSV</em> data to <em>Subsurface</em> <strong>one needs to
know a few things about the data being imported</strong>:</p></div>
<div class="olist loweralpha"><ol class="loweralpha">
<li>
<p>
Which character separates the different columns within a single line of
   data? This field separator should be either a comma (,) or a TAB character.
   This can be determined by opening the file with a text editor. If it is
   comma-delimited, then the comma characters between the values are clearly
   visible. If no commas are evident and the numbers are aligned in columns,
   the file is probably TAB-delimited (i.e. it uses a TAB as a field
   separator).
</p>
</li>
<li>
<p>
Which data columns need to be imported into <em>Subsurface</em>? Is it a <em>CSV dive
   details</em> file or a <em>CSV dive profile</em> file? Open the file using a text
   editor and note the titles of the columns to be imported and their column
   positions.
</p>
</li>
<li>
<p>
Is the numeric information (e.g. dive depth) in metric or in imperial unis?
</p>
</li>
</ol></div>
<div class="paragraph"><p>Armed with this information, importing the data into <em>Subsurface</em> is
straightforward. Select <em>Import &#8594; Import Log Files</em> from the main menu. In
the resulting file selection menu, select <em>CSV files</em> (towards the bottom
right). This shows all .CSV files in the selected directory. Select the file
that needs to be imported. A configuration panel appears as depicted below:</p></div>
<div class="imageblock" style="text-align:center;">
<div class="content">
<img src="images/csv_import1_f20.jpg" alt="FIGURE: CSV download dialogue 1" />
</div>
</div>
<div class="paragraph"><p>Notice that, at the top left, there is a dropdown list containing
pre-configured settings for some of the more common dive computers and
software packages encountered by divers. If the <em>CSV</em> file being imported
originated from any of these pre-configured items, then select it. Otherwise
use the <em>Manual Import</em> option. The configuration panel also has dropdown
lists for the specification of the appropriate field separator (Tab, comma
or semicolon), the date format used in the <em>CSV</em> file, the time units
(seconds, minutes or minutes:seconds), as well as the unit system (metric or
imperial). Selecting the appropriate options among these is critical for the
successful import of the data.</p></div>
<div class="paragraph"><p>The last remaining task is to ensure that all the data columns have the
appropriate column headings. The top line of the white part of the data
table contains the column headings found in the <em>CSV</em> data file. The blue
row of cells immediately above these contains the names understood by
<em>Subsurface</em>. The white area below the dropdown lists contains all the field
names that <em>Subsurface</em> recognises. These names are in blue balloons and can
be moved using a drag-and-drop action. For instance, <em>Subsurface</em> expects
the column heading for Dive number (" # ") to be "Dive # ". If the column
heading that <em>Subsurface</em> expects is not in the blue cells, then drag the
appropriate column heading from the upper area and drop it in the
appropriate blue cell at the top of the table. To indicate the correct
column for "Dive #", drag the ballooned item labeled "Dive # " and drop it
in the blue cell immediately above the white cell containing " # ". This is
depicted in the image below.</p></div>

<td class="content"><em>CSV</em> is an abbreviation for a data file format: <em>Comma-Separated
Values</em>. It is a file format allowing someone to view or edit the
information using a text editor such as Notepad (Windows), gedit (Linux) or
TextWrangler (OS/X). The two main advantages of the <em>CSV</em> format is that the
data are easily editable as text without any proprietary software and
ensuring all information is human-readable, not being obscured by any custom
or proprietary attributes that proprietary software insert into files.
Because of its simplicity the <em>CSV</em> format is used as an interchange format
between many software packages, e.g. between spreadsheet, statistical,
graphics, database and diving software. Within <em>Subsurface</em>, <em>CSV</em> files can
also be used to import information from other sources such as
spreadsheet-based dive logs and even from some dive computers.</td>

</div>
<div class="paragraph"><p><em>CSV</em> files can be created or edited with a normal text editor. The most
important attribute of a <em>CSV</em> file is the <em>field separator</em>, the character
used to separate fields within a single line. The field separator is
frequently a comma, a colon, a SPACE character or a TAB character. When
exporting data from spreadsheet software, the field separator needs to be
specified in order to create the <em>CSV</em> file. <em>CSV</em> files are normally
organised into a single line that provides the headers (or <em>field names</em>) of
the data columns, followed by the data, one record per line. Note that each
field name may comprise more than one word separated by spaces; for instance
<em>Dive site</em>, below. Here is an example of dive information for four dives

in the time range that fit not only the first dive, but one or more
subsequent dives as well).  A workaround for this situation to manually edit

<em>Background service</em>, being a very powerful tool, may fill the location list
  with many unnecessary locations not corresponding to the exact dive point
  but reflecting the boat&#8217;s route.  Currently these locations are difficult to
  delete from the server. In some situations it is therefore prudent to clean
  up the list on the Android device before sending the dive points to the web
  server by simply deleting the inappropriate locations. This might be
  necessary, for instance, if one wants to keep the location list clear to see
  dives in the web service map display (see above).
</p>
</li>
<li>
<p>
It may also make sense to give informative names to the locations sent to

<h3 id="S_LoadImage">5.5. Adding photographs to dives</h3>
<div class="paragraph"><p>Many (if not most) divers take a camera with them and take photographs
during a dive. One would like to associate each photograph with a specific
dive. <em>Subsurface</em> allows one to load photos into a dive. Photos are
superimposed on the dive profile, from where they can be viewed.</p></div>
<div class="sect3">
<h4 id="_loading_photos_and_getting_synchronisation_between_dive_computer_and_camera">5.5.1. Loading photos and getting synchronisation between dive computer and camera</h4>
<div class="paragraph"><p>Left-lick on a dive or on a group of dives on the dive list. Then
right-click on this dive or group of dives and choose the option <em>Load
Images</em>:</p></div>
<div class="imageblock" style="text-align:center;">

<div class="content">
<img src="images/LoadImage2_f20.jpg" alt="FIGURE: Load images option" />
</div>
</div>
<div class="paragraph"><p>This brings one to the time synchronisation dialog, shown below. The
critical problem is that the time synchronisation is not perfect between the
dive computer used during a dive, and the camera used during that same
dive. These two devices often differ by several minutes. If <em>Subsurface</em> can
achieve synchronisation, then the exact times of photographs can be used to
position photographs on the dive profile.</p></div>
<div class="paragraph"><p><em>Subsurface</em> achieves this synchronisation in two ways:</p></div>
<div class="ulist"><ul>
<li>
<p>
<strong>Manually</strong>: If the user wrote down the exact camera time at the start of a dive, the
  difference in time between the two devices can be determined. Actually, as long as the device
  settings for time has not been changed in either device, one could write down the times of
  both devices after the dive or even at the end of the day. One can then manually set the time
  difference in the <em>Time shift</em> dialog. Towards the top of the dialog is a time setting tool
  immediately under the heading <em>Shift times of image(s) by</em>, evident in figure <strong>A</strong> below.
  If the camera time is 7 minutes later than that of the dive computer, set the time setting
  tool to a value of 00:07.  Select either the <em>earlier</em> or <em>later</em> radio button.
  In the above example, the <em>earlier</em> option is appropriate, since the photos need to be shifted
  7 minutes earlier (camera is 7 minutes ahead of dive computer). Ignore any "AM" or "PM" suffix
  in that tool. Click the <em>OK</em> button and synchronisation is achieved.
</p>
</li>
</ul></div>
<div class="imageblock" style="text-align:center;">
<div class="content">
<img src="images/LoadImage3b_f20.jpg" alt="FIGURE: Synchronisation dialog" />
</div>
</div>
<div class="ulist"><ul>
<li>
<p>
<strong>By photograph</strong>: There is a very slick way of achieving synchronisation. If one takes a
  photograph of the face of the dive computer showing the time, then <em>Subsurface</em> can obtain
  the exact time the photograph was taken, using the metadata that the camera stores within
  each photo. In order to do this, use the bottom half of the Time shift_ dialog. If one uses
  the bottom part, the top part of the dialog is ignored. Click on
  the horizontal bar entitled "<em>Select image of divecomputer showing time</em>. This brings up
  a file browser with which one can select the photograph of the dive computer. Select the
  photograph using the file browser and click on <em>OK</em>. This photograph of the dive computer
  appears in the bottom panel of the <em>Shift times</em> dialog. Now <em>Subsurface</em> knows exactly
  when the photograph has been taken. Now set the date-time dialog to the left of the photo
  so that this tool reflects the date and time of the dive computer in the photo. When the
  date-time tool has been set, <em>Subsurface</em> knows exactly what the time difference between
  camera and dive computer is, and synchronisation is achieved. There is a
  photograph with the face of the dive computer and with the date-time tool set to the
  date-time on image <strong>B</strong> above.
</p>
</li>
</ul></div>
<div class="paragraph"><p>If the timestamp of a photograph is long before or after the dive, it is not
placed on the dive profile. If the timestamp of the photo is within 30
minutes of the dive, it is shown.</p></div>

<div class="paragraph"><p>Photographs associated with a dive are shown as thumbnails in the <em>Photos</em>
tab of the <em>Notes</em> panel. Photos taken in rapid succession during a dive
(therefore sometimes with large overlap on the dive profile) can easily be
accessed in the <em>Photos</em> tab. This tab serves as a tool for individually
accessing the photos of a dive, while the stubs on the dive profile give an
indication of when during a dive a photo was taken. By single-clicking on a
thumbnail in the <em>Photos</em> panel, a photo is selected. By double-clicking a
thumbnail, the full-sized image is shown, overlaying the <em>Subsurface</em>
window. A photo can be deleted from the <em>Photos</em> panel by selecting it
(single-click) and then by pressing the <em>Del</em> key on the keyboard. This
removes the photo both from the <em>Photos</em> tab as well as the dive profile.</p></div>

<div class="sect3">
<h4 id="_photos_on_an_external_hard_disk">5.5.4. Photos on an external hard disk</h4>
<div class="paragraph"><p>Most underwater photographers store their photos on an external drive. If
such a drive can be mapped (almost always the case) the photos can be
directly accessed by <em>Subsurface</em>. This facilitates the interaction between
<em>Subsurface</em> and an external repository of photos. When associating a dive
profile with photos from an external drive, the normal procedure of
selection and synchronisation (see text above) is used.  However, after the
external drive has been disconnected, <em>Subsurface</em> cannot access these
photos any more.  If the display of photos is activated (using the toolbox
to the left of the <em>Dive Profile</em>), the program only shows a small white dot
where each photo should be on the dive profile.  In addition the <em>Photos</em>
tab only shows the file names of the photos. This is normal behaviour.  If,
later, the external drive with the photos is connected again, the photos can
be seen in the normal way.</p></div>

<div class="sect3">
<h4 id="S_FindMovedImages">5.5.5. Moving photographs among directories, hard disks or computers</h4>
<div class="paragraph"><p>After a photograph has been loaded into <em>Subsurface</em> and associated with a specific dive, the directory
 where the photo lies is stored, allowing <em>Subsurface</em> to find the photograph when the dive is
 opened again. If the photo or the whole photo collection is moved to another drive or to a different
 machine, it is unlikely that the directory structure will remain identical to that of the original uploaded
 photo. When this happens, <em>Subsurface</em> looks for the photos at their original location before they were moved,
 cannot find them and therefore cannot display them. Because, after moving photos, large numbers of photos
 may need to be deleted and re-imported from the new location, <em>Subsurface</em> has a mechanism that eases the
 process of updating the directory information for each photo: automatic updates using fingerprints.</p></div>
<div class="paragraph"><p>When a photo is loaded into <em>Subsurface</em>, a fingerprint for the image is calculated and stored with the
 other reference information for that photo. After moving a photo collection (that has already been loaded
 into <em>Subsurface</em>) to a different directory, disk or computer, <em>Subsurface</em> can  perform the
 following steps:</p></div>
<div class="ulist"><ul>
<li>
<p>
look through a particular directory (and all its subdirectories recursively)
  where photos have been moved
 to,
</p>
</li>
<li>
<p>
calculate fingerprints for all photos in this directory, and
</p>
</li>
<li>
<p>
if there is a match between a calculated fingerprint and the one originally
  calculated when a photo was
 loaded into <em>Subsurface</em> (even if the original file name has changed), to
 automatically update the directory information so that <em>Subsurface</em> can find
 the photo in the new moved directory.
</p>
</li>
</ul></div>
<div class="paragraph"><p>This is achieved by selecting from the Main Menu: <em>File &#8594;      Find moved images</em>. This brings up a window within
 which the NEW directory of the photos needs to be specified. Select the appropriate directory and click
 the <em>Scan</em> button towards the bottom right of the panel. The process may require several minutes to

<h4 id="S_MulticylinderDives">5.6.1. Multicylinder dives</h4>
<div class="paragraph"><p><em>Subsurface</em> easily handles dives involving more than one
cylinder. Multicylinder diving usually happens (a) if a diver does not have
enough gas for the complete dive in a single cylinder; (b) if the diver
needs more than one gas mixture because of the depth or the decompression
needs of the dive. For this reason multicylinder dives are often used by
technical divers who dive deep or long. As far as <em>Subsurface</em> is concerned,
there are only two types of information that need to be provided:</p></div>
<div class="ulist"><ul>
<li>
<p>
<strong>Describe the cylinders used during the dive</strong> This is performed in the <strong>Equipment tab</strong> of
  the <strong>Info</strong> panel, as <a href="#cylinder_definitions">described above</a>. Enter the cylinders one by one,
  specifying the characteristics of the cylinder and the gas composition within each cylinder.
</p>
</li>
<li>
<p>
<strong>Record the times at which switches from one cylinder to another was done:</strong> This is information
  provided by some dive computers (provided the diver indicated these changes to the dive computer
  by pressing specific buttons). If the dive computer does not provide the information, the diver has to
  record these changes using a different method, e.g. writing it on a slate.
</p>
</li>
<li>
<p>
<strong>Record the cylinder changes on the dive profile</strong>: If the latter option
  was followed, the diver needs to indicate the gas change event by right-clicking at the appropriate point
  in time on the <strong>Dive Profile</strong> panel and indicating the cylinder to which the change was made. After
  right-clicking, follow the context menu to "Add gas change" and select the appropriate cylinder from
  those defined during the first step, above (see image below). If the
  <strong>tank bar</strong> button in the toolbar has been activated, the cylinder switches are also indicated in the
  tank bar.
</p>
</li>
</ul></div>
<div class="paragraph"><p>Having performed these tasks, <em>Subsurface</em> indicates the appropriate use of

<h4 id="_sidemount_dives">5.6.2. Sidemount dives</h4>
<div class="paragraph"><p>Sidemount diving is just another form of multicylinder diving, often with
both or all cylinders having the same gas mixture. Although it is a popular
configuration for cave divers, sidemount diving can be performed by
recreational divers who have completed the appropriate training. Sidemount
dive logging involves, exactly as with multicylinder dives, above, three
steps:</p></div>
<div class="ulist"><ul>
<li>
<p>
<strong>During the dive, record cylinder switch events</strong>. Since sidemount diving normally involves two
  cylinders with air or with the same gas mixture, <em>Subsurface</em> distinguishes among these different
  cylinders. In contrast, most dive computers that allow gas switching only distinguish among different
  <em>gases</em> used, not among different <em>cylinders</em> used. This means that when sidemount dives are downloaded
  from these dive computers, the events of switching between cylinders with the same gas are not downloaded. This may mean
  that one may have to keep a written log of cylinder switch times using a slate, or (if the dive computer
  has this facility) marking each cylinder switch with a bookmark that can be retrieved later. Returning
  from a dive with the information about cylinder changes is the only tricky part of logging sidemount dives.
</p>
</li>
<li>
<p>
<strong>Within <em>Subsurface</em> describe the cylinders used during the dive</strong>. The diver needs to provide the
  specifications of the different cylinders, using the <strong>Equipment</strong> tab of the <strong>Info Panel</strong> (see
  image below where two 12 litre cylinder were used).
</p>
</li>
<li>
<p>
<strong>Indicate cylinder change events on the <em>Subsurface</em> dive profile</strong>. Once the dive log has been imported
  from a dive computer into <em>Subsurface</em>, the cylinder switch events need to be indicated on the dive profile.
  Cylinder changes are recorded by right-clicking at the appropriate point on the dive profile and then
  selecting <em>Add gas change</em>. A list of the appropriate cylinders is shown with the
  currently used cylinder greyed out. In the image below Tank 1 is greyed out, leaving only Tank 2
  to be selected. Select the appropriate cylinder. The cylinder change is then indicated on the dive
  profile with a cylinder symbol. If the <strong>Tank Bar</strong> is activated using the toolbar to the left of the
  profile, then the cylinder change is also indicated on the Tank Bar (see image below). After all
  the cylinder change events have been recorded on the dive profile, the correct cylinder pressures
  for both cylinders are shown on the dive profile, as in the image below.

<td class="content">Passive semi-closed rebreathers (pSCR) comprise a technical advance in
diving equipment that recirculates the breathing gas that a diver breathes,
while removing carbon dioxide from the exhaled gas. While a small amount
(typically a tenth) of the exhaled breathing gas is released into the water,
a small amount of fresh gas is released from the back gas cylinder
(typically containing nitrox).  A diver, using a single cylinder of
breathing gas can therefore dive for much longer periods than using a
recreational open-circuit configuration. With pSCR equipment, a very small
amount of breathing gas is released every time the breather inhales. With
active SCR (aSCR) equipment, in contrast, a small amount of breathing gas is
released continuously from the back cylinder.</td>

<div class="paragraph"><p>The profile can also include the dive computer reported <strong>ceiling</strong> (more
precisely, the deepest deco stop that the dive computer calculated for each
particular moment in time) as a red overlay on the dive profile. Ascent
ceilings arise when a direct ascent to the surface increases the risk of a
diver suffering from decompression sickness (DCS) and it is necessary to
either ascend slower or to perform decompression stop(s) before ascending to
the surface. Not all dive computers record this information and make it
available for download; for example all of the Suunto dive computers fail to
make this very useful data available to divelog software. <em>Subsurface</em> also
calculates ceilings independently, shown as a green overlay on the dive
profile.  Because of the differences in algorithms used and amount of data
available (and other factors taken into consideration at the time of the
calculation) it is unlikely that ceilings from dive computers and from
<em>Subsurface</em> are the same, even if the same algorithm and <em>gradient factors</em>
(see below) are used.  It is also quite common that <em>Subsurface</em> calculates
a ceiling for non-decompression dives when the dive computer stayed in
non-deco mode during the whole dive (represented by the <span class="green">dark green</span>
section in the profile at the beginning of this section). This is caused by
the fact that <em>Subsurface’s</em> calculations describe the deco obligation at
each moment during a dive, while dive computers usually take the upcoming
ascent into account. During the ascent some excess nitrogen (and possibly
helium) are already breathed off so even though the diver technically
encountered a ceiling at depth, the dive still does not require an explicit
deco stop. This feature allows dive computers to offer longer non-stop
bottom times.</p></div>

The light green area indicates the total gas, with the top margin of the
  light green area indicating the total gas pressure inhaled by the diver and

  area. This pressure has a <em>relative</em> value in the graph and does not
  indicate absolute pressure.
</p>
</li>
<li>
<p>
The horizontal black line underneath the light green margin indicates the
  equilibrium pressure of the inert gases inhaled by the diver, usually
  nitrogen. In the case of trimix, it is the pressures of nitrogen and helium
  combined. In this example, the user is diving with EAN32, so the inert gas
  pressure is 68% of the distance from the bottom of the graph to the total
  gas pressure value.
</p>
</li>

The dark green area at the bottom of the graph represents the pressures of

</p>
</li>
<li>
<p>
The top black horizontal line indicates the gradient factor that applies to

<div class="paragraph"><p>These five values are indicated on the left in the graph above. The way the
Gas Pressure Bar Graph changes during a dive is indicated on the right hand
side of the above figure for a diver using EAN32.</p></div>
<div class="ulist"><ul>
<li>
<p>
Graph <strong>A</strong> indicates the situation at the start of a dive with diver at the
  surface. The pressures in all the tissue compartments are still at the
  equilibrium pressure because no diving has taken place.
</p>
</li>
<li>
<p>
Graph <strong>B</strong> indicates the situation after a descent to 30 meters. Few of the
  tissue compartments have had time to respond to the descent, their gas
  pressures being far below the equilibrium gas pressure.
</p>
</li>
<li>
<p>
Graph <strong>C</strong> represents the pressures after 30 minutes at 30 m. The fast
  compartments have attained equilibrium (i.e. they have reached the hight of
  the black line indicating the equilibrium pressure). The slower compartments
  (towards the right) have not reached equilibrium and are in the process of
  slowly increasing in pressure.
</p>
</li>
<li>
<p>
Graph <strong>D</strong> shows the pressures after ascent to a depth of 4.5 meters. Since,
  during ascent, the total inhaled gas pressure has decreased strongly from 4
  bar to 1.45 bar, the pressures in the different tissue compartments now
  exceed that of the total gas pressure and approaches the gradient factor
  value (i.e.  the top black horizontal line). Further ascent will result in
  exceeding the gradient factor value (GFHigh), endangering the diver.
</p>
</li>
<li>
<p>
Graph <strong>E</strong> indicates the situation after remaining at 4.5 meters for 10
  minutes. The fast compartments have decreased in pressure. As expected, the
  pressures in the slow compartments have not changed much.  The pressures in
  the fast compartments do not approach the GFHigh value any more and the
  diver is safer than in the situation indicated in graph <strong>D</strong>.

<div class="paragraph"><p>Sometimes a dive is briefly interrupted, e.g. if a diver returns to the
surface for a few minutes, resulting in two or more dives being recorded by
the dive computer and appearing as different dives in the <strong>Dive List</strong>
panel. Users can merge these dives onto a single dive by selecting the
appropriate dives, right-clicking them to bring up the context menu and then
selecting <strong>Merge selected dives</strong>. It may be necessary to edit the dive
information in the <strong>Notes</strong> panel to reflect events or conditions that apply
to the merged dive. The figure below shows the depth profile of two such
dives that were merged:</p></div>

<h3 id="S_Filter">7.5. Filtering the dive list</h3>
<div class="paragraph"><p>The dives in the <strong>Dive List</strong> panel can be filtered, that is, one can select
only some of the dives based on their attributes, e.g. dive tags, dive site,
dive master, buddy or protective clothing. For instance, filtering allows
one to list the deep dives at a particular dive site, or otherwise the cave
dives with a particular buddy.</p></div>
<div class="paragraph"><p>To open the filter, select <em>Log &#8594; Filter divelist</em> from the main menu. This
opens the <em>Filter Panel</em> at the top of the <em>Subsurface</em> window. Three icons
are located at the top right hand of the filter panel. The <em>Filter Panel</em>
can be reset (i.e. all current filters cleared) by selecting the <strong>yellow
angled arrow</strong>. The <em>Filter Panel</em> may also be minimised by selecting the
<strong>green up-arrow". When minimised, only these three icons are shown.  The
panel can be maximised by clicking the icon that minimised the panel. The
filter may also be reset and closed by selecting the *red button</strong> with the
white cross.  An example of the <em>Filter Panel</em> is shown in the figure below.</p></div>
<div class="imageblock" style="text-align:center;">
<div class="content">
<img src="images/Filterpanel.jpg" alt="Figure: Filter panel" />
</div>
</div>
<div class="paragraph"><p>Four filter criteria may be used to filter the dive list: dive tags, person
(buddy / dive master), dive site and dive suit, each of which is represented
by a check list with check boxes. Above each check list is a second-level
filter tool, allowing the listing of only some of the attributes within that
check list. For instance, typing "<em>ca</em>" in the filter textbox above the tags
check list results in the tags check list being reduced to "<em>cave</em>" and
"<em>cavern</em>". Filtering of the check list enables the rapid finding of search
terms for filtering the dive list.</p></div>
<div class="paragraph"><p>To activate filtering of the dive list, check at least tone check box in one
of the four check lists. The dive list is then shortened to include only the
dives that pertain to the criteria specified in the check lists.  The four
check lists work as a filter with <em>AND</em> operators, Subsurface filters
therefore for <em>cave</em> as a tag AND <em>Joe Smith</em> as a buddy; but the filters
within a category are inclusive - filtering for <em>cave</em> and <em>boat</em> shows
those dives that have either one OR both of these tags.</p></div>

<li>
<p>
<em>Subsurface XML</em> format. This is the native format used by <em>Subsurface</em>.
</p>
</li>
<li>
<p>
Universal Dive Data Format (<em>UDDF</em>). Refer to <em>http://uddf.org</em> for more
  information.  UDDF is a generic format that enables communication among many
  dive computers and computer programs.
</p>
</li>
<li>
<p>
<em>Divelogs.de</em>, an Internet-based dive log repository. In order to upload to
  <em>Divelogs.de</em>, one needs a user-ID as well as a password for
  <em>Divelogs.de</em>. Log into <em>http://en.divelogs.de</em> and subscribe to this
  service in order to upload dive log data from <em>Subsurface</em>.
</p>
</li>
<li>
<p>
<em>DiveShare</em> is also a dive log repository on the Internet focusing on the
  recreational dives. In order to upload dives one has to provide a used ID,
  so registration with <em>http://scubadiveshare.com</em> is required.
</p>
</li>
<li>
<p>
<em>CSV dive details</em>, that includes the most critical information of the dive
  profile. Included information of a dive is: dive number, date, time, buddy,
  duration, depth, temperature and pressure: in short, most of the information
  that recreational divers enter into handwritten log books.
</p>
</li>
<li>
<p>
<em>CSV dive profile</em>, that includes a large amount of detail for each dive,
  including the depth profile, temperature and pressure information of each
  dive.
</p>
</li>
<li>
<p>
<em>HTML</em> format, in which the dive(s) are stored in HTML files, readable with
  an Internet browser. Most modern web browsers are supported, but JavaScript
  must be enabled. This HTML file is not intended to be edited by the users.
  The HTML dive log contains most of the information and also contains a
  search option to search the dive log. HTML export is specified on the second
  tab of the Export dialog (image <strong>B</strong> above). A typical use of this option is
  to export all one&#8217;s dives to a smartphone or a tablet where it would serve
  as a very portable record of dives useful for dive companies that wish to
  verify the dive history of a diver.  This does away with the need to carry
  one&#8217;s original logbook with one when doing dives with dive companies.
</p>
</li>
<li>
<p>
<em>Worldmap</em> format, an HTML file with a world map upon which each dive and
  some information about it are indicated. This map is not editable. However,
  if one selects any of the dive sites on the map, a summary of the dive is
  available in text, as shown in the image below.

<h2 id="S_Cloud_access">9. Keeping a <em>Subsurface</em> dive log in the Cloud</h2>
<div class="sectionbody">
<div class="paragraph"><p>For each diver, dive log information is highly important. Not only is it a
record of diving activities for one&#8217;s own pleasure, but it is important
information required for admission to further training courses or
(sometimes) even diving sites. The security of the dive log is therefore
critical. In order to have a dive log that is resistant to failure of a home
computer hard drive, loss or theft of equipment, the Cloud is an obvious
solution. This also has the added benefit that one can access one&#8217;s dive log
from anywhere in the world without having to carry it with oneself. For this
reason, facilities such as <em>divelogs.de</em> and <em>Diving Log</em> offer to store
dive log information on the Internet.</p></div>
<div class="paragraph"><p><em>Subsurface</em> includes access to a transparently integrated cloud storage
backend that is available to all Subsurface users. In order to use the
<em>Subsurface cloud storage</em> the users need to follow these steps</p></div>
<div class="ulist"><ul>
<li>
<p>
Create a cloud storage account:
</p>
<div class="ulist"><ul>
<li>
<p>
Open the <em>Preferences</em>
</p>
</li>
<li>
<p>
Under <em>Defaults</em>, in the <em>Subsurface cloud storage</em> section, enter
their email address and a password
</p>
</li>
<li>
<p>
Click <em>Apply</em> or <em>Done</em> to send email address and password to the
server
</p>
</li>
<li>
<p>
The server will respond with an email to the given address that
contains a verification PIN
</p>
</li>
<li>
<p>
Enter the PIN in the corresponding field in the <em>Preferences</em> dialog
(this field is only visible while the backend server is waiting for email
address confirmation)
</p>
</li>
<li>
<p>
Click <em>Apply</em> or <em>Done</em> again, the <em>Subsurface cloud storage</em> account
will be marked as verified and the <em>Subsurface cloud storage</em> service can
be used
</p>
</li>
</ul></div>
</li>
<li>
<p>
Use <em>Subsurface cloud storage</em>
</p>
<div class="ulist"><ul>
<li>
<p>
From the <em>File</em> menu users can load and save data to the <em>Subsurface
cloud storage</em> server
</p>
</li>
<li>
<p>
In the <em>Preferences</em>, users can select to use the <em>Subsurface cloud
storage</em> data as their default data file which means that the data from
the <em>Subsurface cloud storage</em> will be displayed when <em>Subsurface</em> starts.
</p>
</li>
</ul></div>
</li>
</ul></div>
<div class="paragraph"><p><em>Subsurface</em> keeps a local copy of the data and <em>Subsurface</em> stays fully
functional if used while offline. <em>Subsurface</em> will simply synchronize the
data with the backend serer the next time it is used while the computer is
online.</p></div>
<div class="paragraph"><p>Although <em>Subsurface</em> offers integrated Cloud storage of dive logs, it is
also simple to achieve this using several of the existing facilities on the
Internet.</p></div>
<div class="paragraph"><p>For instance <a href="http://www.dropbox.com/"><em>Dropbox</em></a> offers a free application
that allows files on the Dropbox servers to be seen as a local folder on
one&#8217;s desktop computer.</p></div>
<div class="imageblock" style="text-align:center;">
<div class="content">
<img src="images/Cloud.jpg" alt="FIGURE: Dropbox folder" />
</div>
</div>
<div class="paragraph"><p>The <em>Dropbox</em> program creates a copy of the <em>Dropbox</em> Internet Cloud content
on one&#8217;s desktop computer. When the computer is connected to the Internet,
the Internet content is automatically updated. Therefore both the <em>Open</em> and
<em>Save</em> of dive logs are done using the local copy of the dive log in the
local <em>Dropbox</em> folder, so there&#8217;s no need for a direct internet
connection. If the local copy is modified, e.g. by adding a dive, the remote
copy in the <em>Dropbox</em> server in the Cloud will be automatically updated
whenever Internet access is available.</p></div>
<div class="paragraph"><p>In this way a dive log in one&#8217;s <em>Dropbox</em> folder can be accessed seamlessly
from the Internet and can be accessed from any place with Internet
access. Currently there are no costs involved for this service. Dropbox
(Windows, Mac and Linux) can be installed by accessing the
<a href="http://www.dropbox.com/install"><em>Install Page on the Dropbox website</em></a>
Alternatively one can use <em>Dropbox</em> as a mechanism to backup one&#8217;s dive
log. To Store a dive log in the Cloud, select <em>File &#8594; Save as</em> from the
<em>Subsurface</em> main menu, navigate to the <em>Dropbox</em> folder and select the
<em>Save</em> button. To access the dive log in the Cloud, select <em>File &#8594; Open
Logbook</em> from the <em>Subsurface</em> main menu and navigate to the dive log file
in the <em>Dropbox</em> folder and select the <em>Open</em> button.</p></div>
<div class="paragraph"><p>Several paid services exist on the Internet (e.g. Google, Amazon) where the
same process could be used for the Cloud-based storage of dive logs.</p></div>

Gradient Factors:* Here users can set the <em>gradient factors</em> used while diving. GF_Low is
   the gradient factor at depth and GF_High is used just below the surface.
   At intermediate depths gradient factors between GF_Low and GF_High are used.
   Gradient factors add conservatism to the nitrogen exposure during a dive, in a
   similar way that many dive computers have a conservatism setting. The lower
   the value of a gradient factor, the more conservative the calculations are with
   respect to nitrogen loading and the deeper the ascent ceilings are. Gradient
   factors of 20/60 are considered conservative and values of 60/90 are considered
   harsh. Checking <strong>GFLow at max depth</strong> box causes GF_Low to be used at the
   deepest depth of a dive. If this box is not checked, GF_Low is applied at
   all depths deeper than the first deco stop. For more information see:

  assuming a sea-level atmospheric pressure of 1.013 bar.
</p>
</li>
<li>
<p>
In the table labeled <em>Available Gases</em>, add the information of the cylinders
  to be used as well as the gas composition within that cylinder. This is done
  in a similar way as for <a href="#S_CylinderData">providing cylinder data for dive   logs</a>. Choose the cylinder type by double clicking the cylinder type and
  using the dropdown list, then specify the work pressure of this cylinder. By
  leaving the oxygen concentration (O2%) filed empty, the cylinder is assumed

  the boxes provided in this dialogue. Add additional cylinders by using the
  "+" icon to the top righthand of the dialogue.

<p>
The profile of the planned dive can be created in two ways:
</p>
<div class="ulist"><ul>
<li>
<p>
Drag the waypoints (the small white circles) on the existing dive profile in
    a way to represent the dive. Additional waypoints can be created by
    double-clicking the existing dive profile. Waypoints can be deleted by
    right-clicking a particular waypoint and selecting the <em>delete</em> item from
    the resulting context menu.
</p>
</li>
<li>
<p>
The most efficient way to create a dive profile is to enter the appropriate
    values into the table marked <em>Dive planner points</em>. The first line of the
    table represents the duration and the final depth of the descent from the
    surface. Subsequent segments describe the bottom phase of the dive.  The <em>CC
    set point</em> column is only relevant for closed circuit divers.  The ascent is
    usually not specified because this is what the planner is supposed to
    calculate.  Add additional segments to the profile by selecting the "+" icon
    at the top right hand of the table. Segments entered into the <em>Dive planner
    points</em> table automatically appear in the <strong>Dive Profile</strong> diagram.
</p>

</li>
</ul></div>
<div class="sect3">
<h4 id="_recreational_dives">13.2.1. Recreational dives</h4>
<div class="paragraph"><p>The <em>Subsurface</em> dive planner allows a sophisticated way of planning
recreational dives, i.e. dives that remain within no-decompression limits.
The dive planner automatically takes into account the nitrogen load incurred
in previous dives. But conventional dive tables are also used in a way that
can take into account previous dives. Why use a dive planner for
recreational dives? Using recreational dive tables, the maximum depth of a
dive is taken into acount. However, few dives are undertaken at a constant
depth corresponding to the maximum depth (i.e. a "square" dive
profile). This means that dive tables overestimate the nitrogen load
incurred during previous dives. The <em>Subsurface</em> dive planner calculates
nitrogen load according to the real dive profiles of all uploaded previous
dives, in a similar way as dive computers calculate nitrogen load during a
dive. This mean that the diver gets <em>credit</em> in terms of nitrogen loading
for not remaining at maximum depth during previous dives, enabling planning
a longer subsequent dive. For the planner to work it is therefore crucial to
upload all previous dives onto <em>Subsurface</em> before performing dive planning.</p></div>
<div class="paragraph"><p>To plan a dive, the appropriate settings need to be defined.</p></div>
<div class="paragraph"><p>Ensure that the date and time is set to that of the intended dive. This
allows calculation of the nitrogen load incurred during previous dives.</p></div>
<div class="ulist"><ul>
<li>
<p>
Immediately under the heading <em>Planning</em> are two checkboxes <em>Recreational</em>
  and <em>Safety Stop</em>.  Check these two boxes.
</p>
</li>
<li>
<p>
Then define the cylinder size, the gas mixture (air or % oxygen) and the
  starting cylinder pressure in the top left-hand section of the planner under
  <em>Available gases</em>.
</p>
</li>
<li>
<p>
The planner calculates whether the specified cylinder contains enough
  air/gas to complete the planned dive. In order for this to be realistic,
  under <em>Gas options</em>, specify an appropriate surface air consumption (SAC)
  rate for <em>Bottom SAC</em>. Suitable values are between 15 l/min and 30 l/min,
  with novice divers or difficult dives requiring SAC rates closer to 30l/min.
</p>
</li>
<li>
<p>
Define the amount of gas that the cylinder must have at the end of the
  bottom section of the dive just before ascent. A value of 50 bar is often
  used.
</p>
</li>
<li>
<p>
Define the depth of the dive by dragging the waypoints (white dots) on the
  dive profile or (even better) defining the appropriate depths using the
  table under <em>Dive planner points</em> as desribed under the previous heading. If
  this is a multilevel dive, set the appropriate dive depths to represent the
  dive plan by adding waypoints to the dive profile or by adding appropriate
  dive planner points to the <em>Dive Planner Points</em> table.
</p>
</li>
<li>
<p>
The ascent speed can be changed. The default ascent speeds are those
  considered safe for recreational divers.
</p>
</li>
</ul></div>
<div class="paragraph"><p>The dive profile in the planner indicates the maximum dive time within
no-deco limits using the Bühlmann ZH-L16 algorithm and the gas and depth
settings specified as described above. The <em>Subsurface</em> planner allows rapid
assessment of dive duration as a function of dive depth, given the nitrogen
load incurred during previous dives. The dive plan includes estimates of the
amount of air/gas used, depending on the cylinder settings specified under
<em>Available gases</em>. If the initial cylinder pressure is set to 0, the dive
duration shown is the true no-deco limit (NDL) without taking into account
gas used during the dive. If the surface above the dive profile is RED it
means that recreational dive limits are exceeded and either the dive
duration or the dive depth needs to be reduced.</p></div>
<div class="paragraph"><p>Below is an image of a dive plan for a recreational dive at 30
metres. Although the no-deco limit (NDL) is 23 minutes, the duration of the
dive is limited by the amount of air in the cylinder, reflected by the

<div class="paragraph"><p>Non-recreational dive planning involves exceeding the no-deco limits and/or
using multiple breathing gases.  Such dives are planned in three stages:</p></div>
<div class="paragraph"><p><strong>a) Nitrogen management</strong>: This is performed by specifying the rates for descent and ascent,
as well as the gradient factors (GFLow and GFHigh) under the headings <em>Rates</em> and <em>Planning</em>
to the bottom left of the planning screen. Initially, the GFHigh and GFLow values in the <em>Preferences</em>
panel of <em>Subsurface</em> is used. If these are changed within the planner (see <em>Gas Options</em> within
the planner), the new values are
used without changing the original values in the <em>Preferences</em>. Gradient Factor settings strongly affect the calculated ceilings and their depths.
A very low GFLow value brings about decompression stops early on during the dive.

</p>
</li>
</ul></div>
<div class="paragraph"><p>The ascent rate is critical for nitrogen off-gassing at the end of the dive
and is specified for several depth ranges, utilising the average (or mean)
depth as a yardstick. The mean depth of the dive plan is indicated by a
light grey line on the dive profile. Ascent rates at deeper levels are often
in the range of 8-12 m/min, while ascent rates near the surface are often in
the range of 4-9 m/min. The descent rate is also specified. If the option
<em>Drop to first depth</em> is activated, then the descent phase of the planned
dive will be at the maximal descent rate specified in the <em>Rates</em> section of
the dive setup.</p></div>
<div class="paragraph"><p><strong>b) Oxygen management</strong>: In the <strong>Gas Options</strong> part of the dive specification, the maximum partial
pressure for oxygen needs to be specified for the
bottom part of the dive (<em>bottom po2</em>) as well as for the decompression part of the dive (<em>deco po2</em>).
The most commonly
used values are 1.4 bar for the bottom part of the dive and 1.6 bar for any decompression
stages. Normally, a partial pressure of 1.6 bar is not exceeded. PO2 settings and the depth at which switching to a gas takes place can also be edited in the
<em>Available Gases</em> dialog. Normally the planner decides on switching to a new gas when, during
ascent, the partial pressure of the new gas has increased to 1.6 bar.</p></div>
<div class="paragraph"><p><strong>c) Gas management</strong>: With open-circuit dives this is a primary consideration. One needs to keep within the limits of the amount of gas within the dive
cylinder(s), allowing for an appropriate margin for a safe return to the surface, possibly
sharing with a buddy. Under the <em>Gas Options</em> heading, specify the best (but conservative) estimate
of your surface-equivalent air consumption (SAC, also termed RMV) in
litres/min (for the time being, only SI units are supported).  Specify the SAC during the
bottom part of the dive (<em>bottom SAC</em>) as well as during the decompression or safety stops of the
dive (<em>deco SAC</em>). Values of 15-30 l/min are common. For good gas management, a thumbsuck guess
is not sufficient and one needs to
monitor one&#8217;s gas consumption on a regular basis, dependent on different dive conditions and/or equipment.
The planner calculates the total volume of gas used during the dive and issues a warning
if one exceeds the total amount of gas available. Good practice demands that one does not dive to
the limit of the gas supply but that an appropriate reserve is kept for unforeseen circumstances.
For technical diving, this reserve can be up to 66% of the total available gas.</p></div>
<div class="paragraph"><p>Now (at last) one can start the detailed time-depth planning of the
dive. <em>Subsurface</em> offers a unique graphical interface for performing this
part of the planning. The mechanics of doing this is similar to
hand-entering a dive profile in the dive log part of <em>Subsurface</em>. Upon
activating the planner, a default dive of depth 15 m for 40 min is offered
in the bue design surface to the top right hand of the screen. The white
dots (waypoints) on the profile can be dragged with a mouse. Create more
waypoints by double-clicking on the profile line and ensuring that the
profile reflects the intended dive. Drag the waypoints to represent the
depth and duration of the dive. It is NOt necessary to specify the ascent
part of the dive since the planner calculates this, based on the settings
that have been specified.  If any of the management limits (for nitrogen,
oxygen or gas) is exceeded, the surface above the dive profile changes from
BLUE to RED.</p></div>
<div class="paragraph"><p>Each waypoint on the dive profile creates a <em>Dive Planner Point</em> in the
table on the left of the dive planner panel. Ensure that the <em>Used Gas</em>
value in each row of that table corresponds to one of the gas mixtures
specified in the <em>Available Gases</em> table.  Add new waypoints until the main
features of the dive have been completed, e.g. the bottom time segment and
deep stops (if these are implemented). Leave the remaining waypoints on the
ascent to <em>Subsurface</em>. In most cases <em>Subsurface</em> computes additional way
points in order to fulfill decompression requirements for that dive. A
waypoint can be moved by selecting that waypoint and by using the arrow
keys.  The waypoints listed in the <em>Dive Planner Points</em> dialogue can be
edited by hand in order to obtain a precise presentation of the dive
plan. In fact, one can create the whole dive profile by editing the <em>Dive
Planner Points</em> dialog.</p></div>
<div class="paragraph"><p>Indicate any changes in gas cylinder used by indicating gas changes as
explained in the section <a href="#S_CreateProfile">hand-creating a dive profile</a>. These changes should reflect the cylinders and gas compositions
defined in the table with <em>Available Gases</em>.  If two or more gases are used,
automatic gas switches will be suggested during the ascent to the
surface. However, these changes can be deleted by right-clicking the gas
change and by manually creating a gas change by right-clicking on the
appropriate waypoint.</p></div>
<div class="paragraph"><p>A non-zero value in the "CC set point" column of the table of dive planner
points indicates a valid setpoint for oxygen partial pressure and that the
segment is dived using a closed circuit rebreather (CCR). If the last
manually entered segment is a CCR segment, the decompression phase is
computed assuming the diver uses a CCR with the specified set-point. If the
last segment (however short) is on open circuit (OC, indicated by a zero
set-point) the decompression is computed in OC mode. The planner only

<h3 id="_planning_pscr_dives">13.3. Planning pSCR dives</h3>
<div class="paragraph"><p>To plan a dive using a passive semi-closed rebreather (pSCR), select <em>pSCR</em> rather than
<em>Open circuit</em> in the dropdown list.
The parameters of the pSCR diver can be set by selecting  <em>File &#8594;   Preferences &#8594;   Graph</em>
from the main menu, where the gas consumption calculation takes into account the pSCR dump
ratio (default 10:1) as well as the metabolism rate. The calculation also takes the oxygen drop
accross the mouthpiece of the rebreather into account. If the
pO<sub>2</sub> drops below what is considered a save value, a warning appears in the <em>Dive plan
details</em>. A typical pSCR configuration is with a single cylinder and one or more bail-out
cylinders. Therefore the setup of the <em>Available gases</em> and the <em>Dive planner points</em> tables
are very similar to that of a CCR dive plan, described above. However, no oxygen setpoints
are specified for pSCR dives. Below is a dive plan for a pSCR dive. The dive is comparable
to that of the CCR dive above, but note the longer ascent duration due to the lower oxygen
in the loop due to the oxygen drop across the mouthpiece of the pSCR equipment.</p></div>

<h3 id="_planning_ccr_dives">13.4. Planning CCR dives</h3>
<div class="paragraph"><p>To plan a dive using a closed circuit rebreather, select the <em>CCR</em> option in
the dropdown list, circled in blue in the image below.</p></div>
<div class="paragraph"><p><strong>Available gases</strong>: In the <em>Available gases</em> table, enter the cylinder information for the
diluent cylinder and for any bail-out cylinders. Do NOT enter the information for the oxygen
cylinder since it is implied when the <em>CCR</em> dropdown selection is made.</p></div>
<div class="paragraph"><p><strong>Entering setpoints</strong>: Specify a default setpoint in the Preferences tab, by selecting <em>File &#8594;  Preferences &#8594;  Graph</em> from the main menu. All user-entered segments in the <em>Dive planner points</em> table
use the default setpoint value. Then, different setpoints can be specified for dive segments
in the <em>Dive planner points</em> table. A zero setpoint
means the diver bails out to open circuit mode for that segment. The decompression is always calculated
using the setpoint of the last manually entered segment. So, to plan a bail out ascent for a
CCR dive, add a one-minute dive segment to the end with a setpoint value of 0. The decompression
algorithm does not switch deco-gases automatically while in CCR mode (i.e. when a positive setpoint is specified) but, of course, this is calculated for bail out ascents.</p></div>
<div class="paragraph"><p>The dive profile for a CCR dive may look something like the image below.</p></div>
<div class="imageblock" style="text-align:center;">
<div class="content">
<img src="images/Planner_CCR1_f20.jpg" alt="FIGURE: Planning a CCR dive: setup" />
</div>
</div>
<div class="paragraph"><p>Note that, in the <em>Dive plan details</em>, the gas consumption for a CCR segment
is not calculated, so gas consumptions of 0 litres are the norm.</p></div>
</div>
<div class="sect2">
<h3 id="S_Replan">13.5. Modifying an existing dive plan</h3>
<div class="paragraph"><p>Normally, when a dive plan has been saved, it is accessible from the <strong>Dive
List</strong>, like any other dive log. Within the <strong>Dive List</strong> there is not a way to
change a saved dive plan.  To perform changes to a dive plan, select it on
the <strong>Dive List</strong>. Then, in the main menu, select <em>Log &#8594; Re-plan dive</em>. This
will open the selected dive plan within the dive planner, allowing changes
to be made and saved as usual.</p></div>
<div class="paragraph"><p>In addition there is the option "Save new". This keeps the original planned
dive and adds a (possibly modified) copy to the dive list. If that copy is
saved with the same start time as the original, the two dives are considered
two versions of the same dive and do not influence other each during
decompression calculation (see next section).</p></div>
</div>
<div class="sect2">
<h3 id="_planning_for_repetitive_dives">13.6. Planning for repetitive dives</h3>
<div class="paragraph"><p>Repetitive dives can easily be planned if the dates and start times of the
repetitive dive set is specified appropriately in the top left-hand <em>Start
Time</em> field. <em>Subsurface</em> calculates the gas loading figures correctly and
the effect of the first dive is evaluated on later dives.</p></div>
<div class="paragraph"><p>If one has just completed a long/deep dive and is planning another dive,
then highlight, in the <strong>Dive List</strong>, the dive that has just been completed
and then activate the planner. Depending on the start time of the planned
dive, the planner takes into account the gas loading incurred during the
completed dive and allows planning within these limitations.</p></div>
<div class="paragraph"><p>If only a few standard configurations are used (e.g. in GUE), then a
template dive can be created conforming to one of the configurations. If one
now wishes to plan a dive using this configuration, just highlight the
template dive in the <strong>Dive List</strong> and activate the planner: the planner takes
into account the configuration in the highlighted dive.</p></div>
</div>
<div class="sect2">
<h3 id="_printing_the_dive_plan">13.7. Printing the dive plan</h3>
<div class="paragraph"><p>Selecting the <em>Print</em> button in the planner allows printing of the <em>Dive
Plan Details</em> for wet notes. Alternatively one can cut and paste the <em>Dive
Plan Details</em> for inclusion in a text file or word processing document.</p></div>
<div class="paragraph"><p>Dive plans have many characteristics in common with dive logs (dive profile,
dive notes, etc).  After a dive plan has been saved, the dive details and
gas calculations are saved in the <strong>Notes</strong> tab. While a dive plan is being
designed, it can be printed using the <em>Print</em> button in the dive
planner. This prints the dive details and gas calculations in the <em>Dive Plan
Details</em> panel of the dive planner. However, after the plan has been saved,
it is represented in a way very similar to a dive log and the gas
calculations cannot be accessed in the same way as during the planning
process. The only way to print the dive plan is to use the <em>File &#8594; Print</em>
facility on the main menu in the same way as for dive logs or by copy and
paste to a word processor.</p></div>

of the toolbar at the top of the screen.  Users have reported difficulties
with some Bluetooth controllers.  If you have an onboard controller, try
that first.  It is simplest if you remove any USB Bluetooth dongles.  If you
have a USB dongle that came with your dive computer, try that before any
others.</p></div>
<div class="paragraph"><p>Setting up a connection to download dives from your Bluetooth-enabled

<div class="paragraph"><p>Ensure the dive computer is in upload mode. On the <em>Shearwater Petrel</em> and

The display will read <em>Initializing</em>, then <em>Wait PC 3:00</em> and will
countdown.  Once the connection is established, the display reads <em>Wait CMD
&#8230;</em> and the countdown continues. When downloading the dive from Subsurface,
the display reads <em>Sending</em> then <em>Sent Dive</em>.</p></div>
<div class="paragraph"><p>To establish the connection, establish root access through <code>sudo</code> or <code>su</code>.
The correct permission is required to download the dives in the computer. On
most Linux systems this means becoming a member of the dialout group (This
is identical as for many dive computers using a Linux USB port, descibed in
the previous section). On the command terminal, enter:</p></div>

<td class="content"><em>Subsurface</em> downloads the information stored on the SDA (the built-in file
system of the Uemis) including information about dive spots and
equipment. Buddy information is not yet downloadable.  Things are very
similar to a normal USB-connected dive computer (the Uemis is one of those
that recharge when connected to the USB port).  The main difference is that
one does not enter a device name, but instead the location where the
UEMISSDA file system is mounted once connected to the dive computer. On
Windows this is a drive letter ( often <em>E:</em> or <em>F:</em>), on a Mac this is
<em>/Volumes/UEMISSDA</em> and on Linux systems this differs depending on the
distribution. On Fedora it usually is
<em>/var/run/media/&lt;your_username&gt;/UEMISSDA</em>. In all cases <em>Subsurface</em> should
suggest the correct location in the drop down list.</td>

</div>
<div class="paragraph"><p>After selecting the above device name, download the dives from the Uemis
Zurich. One technical issue with the Uemis Zurich download implementation
(this is a Uemis firmware limitation, not a <em>Subsurface</em> issue) is that one
cannot download more than about 40-50 dives without running out of memory on
the SDA. This will usually only happen the very first time one downloads
dives from the Uemis Zurich.  Normally when downloading at the end of a day
or even after a dive trip, the capacity is sufficient. If <em>Subsurface</em>
displays an error that the dive computer ran out of space the solution is
straight forward.  Disconnect the SDA, turn it off and on again, and
reconnect it. You can now retry (or start a new download session) and the
download will continue where it stopped previously. One may have to do this
more than once, depending on how many dives are stored on the dive computer.</p></div>

<h3 id="_subsurface_appears_to_miscalculate_gas_consumption_and_sac">20.1. Subsurface appears to miscalculate gas consumption and SAC</h3>
<div class="paragraph" id="SAC_CALCULATION"><p><em>Question</em>: I dived with a 12.2 l tank, starting with 220 bar and ending
with 100 bar, and I calculate a different SAC compared what <em>Subsurface</em>
calculates. Is <em>Subsurface</em> miscalculating?</p></div>
<div class="paragraph"><p><em>Answer</em>: Not really. What happens is that <em>Subsurface</em> actually calculates
gas consumption differently - and better - than you expect.  In particular,
it takes the incompressibility of the gas into account.  Traditionally, Gas
consumption and SAC should be: <code>consumption = tank size x (start pressure -
end pressure)</code></p></div>
<div class="paragraph"><p>and that&#8217;s true for an ideal gas, and it&#8217;s what you get taught in dive
theory.  But an "ideal gas" doesn&#8217;t actually exist, and real gases actually
don&#8217;t compress linearly with pressure. Also, you are missing the fact that
one atmosphere of pressure isn&#8217;t actually one bar.  So the <strong>real</strong>
calculation is:</p></div>
<div class="paragraph"><p><code>consumption = (amount_of_air_at_beginning - amount_of_air_at_end)</code></p></div>
<div class="paragraph"><p>where the amount of air is <strong>not</strong> just "tank size times pressure in bar".
It&#8217;s a combination of: "take compressibility into account" (which is a
fairly small issue under 220 bar - you&#8217;ll see more differences when you do
high-pressure tanks with 300bar) and "convert bar to atm" (which is the
majority of your discrepancy).  Remember: one ATM is ~1.013 bar, so without
the compressibility, your gas use is:</p></div>
<div class="paragraph"><p><code>12.2*((220-100)/1.013)</code></p></div>
<div class="paragraph"><p>which is about 1445, not 1464. So there was 19 l too much in your simple
calculation that ignored the difference between 1 bar and one ATM.  The
compressibility does show up above 200 bar, and takes that 1445 down about
eight litres more, so you really did use only about 1437 l of air at surface
pressure.</p></div>
<div class="paragraph"><p>So be happy: your SAC really is better than your calculations indicated.  Or
be sad: your cylinder contains less air than you thought it did.  And as
mentioned, the "contains less air than you thought it did" really starts
becoming much more noticeable at high pressure. A 400 bar really does not
contain twice as much air as a 200 bar one. At lower pressures, air acts
pretty much like an ideal gas.</p></div>

<h3 id="_some_dive_profiles_have_time_discrepancies_with_the_recorded_samples_from_my_dive_computer_8230">20.2. Some dive profiles have time discrepancies with the recorded samples from my dive computer&#8230;</h3>
<div class="paragraph"><p><em>Subsurface</em> ends up ignoring surface time for many things (average depth,
divetime, SAC, etc).  <em>Question</em>: Why do dive durations in my dive computer
differ from that given by <em>Subsurface</em>?</p></div>
<div class="paragraph"><p><em>Answer</em>: For example, if you end up doing a weight check (deep enough to
trigger the "dive started")  but then come back up and wait five minutes for
your buddies, your dive computer may say that your dive is 50 minutes long -
because you have fifty minutes worth of samples - but subsurface will say
it&#8217;s 45 minutes - because you were actually diving for 45 minutes.  It&#8217;s
even more noticeable if you do things like divemastering the initial OW
dives, when you may stay in the water for a long time, but spend most of it
at the surface. And then you don&#8217;t want that to count as some kind of long
dive”.</p></div>

<div class="sect2">
<h3 id="_some_dive_profiles_are_missing_from_the_download">20.3. Some dive profiles are missing from the download</h3>
<div class="paragraph" id="DC_HISTORY"><p><em>Question</em>: I cannot download all my dives, only the most recent ones even
though my dive computer&#8217;s manual states that it records history of e.g. 999
dives.</p></div>
<div class="paragraph"><p><em>Answer</em>: Dive history is different than the dive profiles on the log.  The
history only keeps track of the total number of dives and total amount of
time spent below surface. The logs, on the other hand, store the dive
profile, but they have limited amount of memory to do so. The exact amount
of dive profiles that can be stored on the device depend on sample interval
and duration of the dives. Once the memory is full the oldest dives get
overwritten with new dives. Thus we are only able to download the last 13,
30 or 199 dives.</p></div>
<div class="paragraph"><p>If you have downloaded your dives to different dive logging software before
they were overwritten, there is a high change that Subsurface can import
these. However, if the logs are only on your dive computer, they cannot be
salvaged after being over written by new dives.</p></div>
