[MIS15-P16] Modeling the evolution of the Antarctic ice sheet driven by basal melting using the three-dimensional ice sheet model SICOPOLIS
Keywords:Antarctic ice sheet, ice shelf, basal melting, ice sheet model
In this study, we use the three-dimensional ice sheet model SICOPOLIS to investigate steady states of the Antarctic ice sheet with various basal melting rates beneath ice shelves, starting from the present-day ice sheet as initial condition. We analyze the response of the whole Antarctic ice sheet as well as that of specific areas, namely the Siple Coast, Wilkes, Aurora and Recovery subglacial basins. Siple Coast is located in West Antarctica, at the east side of the Ross Ice Shelf, while the other basins are located in East Antarctica. All areas have large ice shelves, so that they are highly sensitive to the basal melting beneath ice shelves. We also investigate steady states of the Antarctic ice sheet at various sea levels relative to the present to take into account the influence of glacial-interglacial cycles.
