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.

Have a little whistle we give,

We dive down under the farm.”
