Ocean

Oceanic variables include sea surface temperature, salinity, currents, air-sea heat fluxes, ocean heat content, and much more. Overview pages summarize and compare selected datasets of a given variable.

To find a specific dataset or variable, jump to the search box below or click your desired variable from among the blue sub-category buttons.

To see only the datasets with expert-written commentaries, select the "Datasets with guidance" button when using the search box.
