Reconstruction of the circulation in the Gulf of Alaska 2007

Goals: (1) Reconstruct the circulation during 2007 in the Gulf of Alaska; (2) Develope prototype of the data assimilation system for the region; (3) Estimate local tansports

Data: (1) Hydrophysicals section during July 2007 (2) Argo CTD and velocities (3) Drifters (4) Meteorological data
