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:
“He who is of a calm and happy nature will hardly feel the pressure of age, but to him who is of an opposite disposition youth and age are equally a burden.”
—Plato (c. 427–347 B.C.)
“A society which allows an abominable event to burgeon from its dungheap and grow on its surface is like a man who lets a fly crawl unheeded across his face or saliva dribble unstemmed from his mouth—either epileptic or dead.”
—Jean Baudrillard (b. 1929)
