Late-Holocene advance of the Collins Ice Cap, King George Island, South Shetland Islands

Department of Earth Sciences and Climate Change Institute, University of Maine, Orono ME 04469, USA, BrendaH{at}maine.edu

Radiocarbon dates of incorporated moss indicate advance of the Collins Ice Cap on Fildes Peninsula (King George Island) after ~650 cal. yr BP (~AD 1300), broadly contemporaneous with the `Little Ice Age', as defined in Europe. During that time, the glacier extended less than 400—500 m beyond its present-day margin. Moreover, radiocarbon data indicate that this was the most extensive advance of the last 3500 cal. years. Prior to ~650 cal. yr BP, the ice must have been at or behind its present position. Furthermore, the data indicate that climate conditions prior to the late-Holocene advance may have been similar to (or possibly warmer than) today.

Key Words: South Shetland Islands • Fildes Peninsula • late-Holocene ice extent • moraines • `Little Ice Age'.
