Reconstruction of the circulation in the Eastern Bering Sea during 2007-2010
Goals:
(1) Reconstruct the circulation; (2) Estimates of the transports;
(3) Estimates of the eddy transport accors the slope;
(4) Define the factors that control circulation in the Eastern Bering Sea shelf;
Data: (1) Climatological temperature/salinity data;
(2) 6 moorings in the Aleutian Passes, moorings in the Bering Strait;
(3) SSH altimetry data
(4) Meteorological data
