Abstract
Observations based on mooring stations as well as hydrographic survey have shown that Circumpolar Deep Water (CDW) intrusion and behaviors in the Amundsen Sea Embayment show year-to-year variations. In this study, we analyzed model data (2001-2016) of a high-resolution MITgcm ocean model that allows ocean-ice shelf interaction, by comparing with observational data including a recent Araon expedition. We find that distinct patterns in hydrographic profiles observed in 2012 and 2014 attribute to wind stress curl and its relevant up- and downwelling processes in the oceanic interior.
