Ambient Pressure On The Surface
Sometimes changes in ambient pressure, while diver is on the surface, are drawn on a dive profile. The changes may be caused by flying, land travel involving changes in altitude, or atmospheric pressure changes due to weather. Ambient pressure changes before and after diving can be significant in decompression planning. Starting dives at altitude also has an impact on dive and decompression planning.

Famous quotes containing the words pressure and/or surface:
“This is a catastrophic universe, always; and subject to sudden reversals, upheavals, changes, cataclysms, with joy never anything but the song of substance under pressure forced into new forms and shapes.”
—Doris Lessing (b. 1919)
“When we are in love, the sentiment is too great to be contained whole within us; it radiates out to our beloved, finds in her a surface which stops it, forces it to return to its point of departure, and it is this rebound of our own tenderness which we call the other’s affection and which charms us more than when it first went out because we do not see that it comes from us.”
—Marcel Proust (1871–1922)
