Baroclinic ocean response to climate forcing regulates decadal variability of ice-shelf melting in the Amundsen Sea
This dataset provides model output for the 1979-2019 ice-ocean simulations in the Amundsen Sea, Antarctica. The simulation is performed with the MITgcm model at 1/10 degree resolution, including components for the ocean, sea ice, and ice shelf thermodynamics. Atmospheric forcing is provided by ECMWF...
