Science - Ocean-Atmosphere Interaction: People: Victor Zlotnicki

Southern Ocean Circulation using Ocean Bottom Pressure, Sea Surface Height, and Wind data
Investigations of southern ocean circulation, by applying a combination of ocean bottom pressure (measured indirectly using time-variable gravity from the GRACE mission), sea surface height (measured by radar altimetry from TOPEX, Jason and other satellites), and surface winds (from Quikscat scatterometry). Interest and ability to assimilate ocean bottom pressure into an existing numerical model / data assimilation system using an existing Kalman filter approach is a plus. Need not have expertise in the data types.

ECCO2
ECCO2 is an ECCO-follow-on project that aims to produce increasingly accurate syntheses of all available global-scale ocean and sea-ice data at resolutions that start to resolve ocean eddies.

GRACE-Tellus
Produces and delivers high-quality, easy-to use data products derived from the GRACE mission.
