-in the range of 8-12 m/min, while ascent rates near the surface are often in

-<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

-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’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

-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,

-features of the dive have been completed, e.g. the bottom time segment and

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’s true for an ideal gas, and it’s what you get taught in dive
-theory. But an "ideal gas" doesn’t actually exist, and real gases actually
-don’t compress linearly with pressure. Also, you are missing the fact that
-one atmosphere of pressure isn’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’s a combination of: "take compressibility into account" (which is a
-fairly small issue under 220 bar - you’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
