Copyright © The Oceanographic Society of Japan. Mass, Heat and Salt Balances in the Eastern Barents Sea Obtained by Inversion of Hydrographic Section Data
Standard hydrological section data, collected in the eastern Barents Sea in Septem-ber 1997, have been analyzed using a variational data assimilation technique. This method allows us to obtain temperature, salinity and velocity fields that are consist-ent with observations and dynamically balanced w...
