Argo is an array of over 3600 profiling floats distributed almost uniformly across the global oceans. First deployed in 2000, Argo floats provide temperature and salinity profiles from the surface to a depth of 2000m. The array has approximately 1 float for every 3 degrees of latitude and...

GODAS is a real-time ocean analysis and a reanalysis. It is used for monitoring, retrospective analysis as well as for providing oceanic initial conditions for the CFS. Both temperature and synthetic salinity profiles are assimilated in a 3DVAR scheme. Beginning with March 2007, altimetry sea level...

ECMWF's current ocean reanalysis uses a sophisticated data assimilation methodology which includes a model bias correction. The ocean model used is forced by atmospheric daily surface fluxes, relaxed to SST and bias corrected.
The Balmaseda et al (QJRMS 2013) reference provides excellent peer...

The Southern Ocean State Estimate (SOSE) is a model-generated best fit to Southern Ocean observations. As such, it provides a quantitatively useful climatology of the mean-state of the Southern Ocean. Technically, SOSE is a solution to the MITgcm. SOSE is a gridded dataset at 1/6...
