Abstract
The chronology of post-last Glacial Maximum dceglaciation in the northern Antarctic Peninsula region is discussed. It is concluded that, contrary to what was earlier believed, the deglaciation process here was largely out-of-phase with that in the Northern Hemisphere. Although, for global eustatic reasons, the marine-based glaciers may have retreated simultaneously with ice-melting in the Northern Hemisphere, the land-based glaciers retreated only slowly during the first half of the Hulocene, about 9000-5000 BP. This may have been due either to increased precipitation counterweighing ablation or to delayed warming: A distinct but rather brief glacial readvance took place. around 5000 BP, probably caused by a period of renewed cooling It...
