Rock Bottom Volume/Pressure Calculation Calculating Emergency Reserve Needed - Rock Bottom One of our primary concepts, and a UTD covenant, is Rock Bottom Gas Planning. Rock bottom is the absolute minimum volume or pressure of gas needed for two divers, while air-sharing, to ascend to the next available gas source while conducting all required decompression, deep stops or safe ascent profile stops.
