Reconstruction of the circulation during 1990-1991

Attention: all temperature, salinity, velocity and SSH fields are availabed upon request. Please send your requests to gleb@iarc.uaf.edu

Goals: (1) Reconstruct the circulation; (2) Estimates of the ice-ocean heat/salt fluxes; (3) Estimates of the transport

Data: (1) Hydrophysicals surveys during September and October 1990 and October 1991 (2) 11 moorings with CTD and current meters (3) Meteorological data

Figure 1. Blue dots - CTD surveys during September and October 1990 and October 1991. Red dots - 11 moorings. Yellow line - model domain for the future study. Green line - model domain for the pilot study.

Pilot study: Reconstruction of the circulation during October-November 1990.

Assimilation of the 9-days low-passed velocity and CTD data.
