Description
Summary:The huge ice shelves in West Antarctica -the Ross and Filchner/Ronne Ice Shelves- habe probably extended out on th continental shelf during the late Wisconsin (Stuiver et al., 1981). Previous discussions, which have focused on the Ross Sea, have suggested (1) that the ice extended across the whole continental shelf (Denton et al., 1975; Kellog et al., 1979, doi:10.1130/0091-7613(1979)7<249:LQEOTW>2.0.CO;2) or (2) that there was only a minor ecpansion (Drewry, 1979). Here we present sedimentological data from the Weddel Sea which suggests that a late Wisconsin grounded ice sheet extended to the shelfe edge. The evidence includes a recent thicker ice in Ellsworth Mountains at the head of the Filchner/Ronne Ice Shelf (Rutford et al., 1980). This thickening would lead to an expansion of the inland ice sheet over the continental shelf, filling up the Weddell Sea embayment.
