A dive profile is a description of a diver's pressure exposure. It may be as simple as just a depth and time pair, as in: "sixty for twenty," (a stay of 20 minutes at a depth of 60 feet) or as complex as a second by second graphical representation of depth and time.
It is useful as an indication of the risks of decompression sickness and oxygen toxicity and also the volume of open-circuit breathing gas needed for a planned dive as these depend in part upon the depth and duration of the dive. A dive profile diagram is often drawn with time running from left to right and depth increasing down the page.

Famous quotes containing the words dive and/or profile:
“I have no time to read newspapers. If you chance to live and move and have your being in that thin stratum in which the events which make the news transpire—thinner than the paper on which it is printed—then these things will fill the world for you; but if you soar above or dive below that plane, you cannot remember nor be reminded of them.”
—Henry David Thoreau (1817–1862)
“Expecting rain, the profile of a day
Wears its soul like a hat....”
—John Ashbery (b. 1927)
