摘要: The huge ice shelves in West Antarctica—the Ross and Filch-ner/Ronne Ice Shelves—have probably extended out on the continental shelf during late Wisconsin1. Previous discussions, which have focused Sea, suggested (1) that across whole shelf2,3 or (2) there was only a minor expansion4. Here we present sedimentological data from Weddell Sea (Fig. 1) suggest Wisconsin grounded sheet to edge. evidence includes recent thicker Ellsworth Mountains at head of Filchner/Ronne Shelf5. This thickening would lead an expansion inland over shelf, filling up embayment
