| Popis: | Here we present initial results from a coupled configuration of the BISICLES ice sheet and NEMO ocean models for the Amundsen Sea Embayment. We use NEMO 4.2 with ice shelf cavity circulation enabled on a 0.25 degree horizontal grid with 75 vertical levels. Our initial focus is on producing a credible simulation of recent changes in the oceanography of the area before comparing the patterns of ice shelf melt predicted by NEMO with those required by BISICLES to generate patterns of ice thinning and grounding line retreat similar to observations. Forcing for these experiments comes from the UKESM CMIP6 simulations, currently for the historical period but with the intention of producing projections to 2100 of ice loss from the area.
