A New 20-year Ocean Climatology

Salinity misfits to Gouretski and Koltermann (2004) at 105m (top) and 2084m (bottom).

[29-Oct-2018] A new 20-year ocean climatology has been created for ocean circulation and climate studies based on the recent ECCO Version 4 release 3 ocean state estimate. In comparison to conventional climatologies based on observations alone, the new ECCO climatology accounts for the very great inhomogeneity with which the ocean has been observed.

The new climatology includes all conventional variables of a general circulation model over the entire water column and is consistent with the diversity of data available from the global observation system. All basic convservation rules for ocean circulation, including enthalpy and energy, are obeyed to machine precision in the model equations.
