The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

Definition: | A conventional definition introduced into oceanography for purposes of brevity. It is the remainder of subtracting 1000 kg m-3 from the density of a sea water sample at atmospheric pressure. The density of water ranges from from 1000 kg m-3 to about 1028 kg m-3
for the densest ocean surface water, so sigma-t ranges from about 0.00 to 28.00, with the units usually omitted. |
