Small cirque glaciers retreat on Keller Peninsula, Admiralty Bay, King George Island, Antarctica

Variations in the total area covered by four small corrie glaciers in the eastern slopes of Keller Peninsula, Admiralty Bay, King George Island (KGI) are investigated using a topographical survey, carried out in the austral summers of 1992/93 and 1993/94. For this survey, aerial photographs, satelli...

Description
Summary:Variations in the total area covered by four small corrie glaciers in the eastern slopes of Keller Peninsula, Admiralty Bay, King George Island (KGI) are investigated using a topographical survey, carried out in the austral summers of 1992/93 and 1993/94. For this survey, aerial photographs, satellite images and mapping surveys (from the 1950s onwards) were compared. All four glaciers have lost between 44 to 83% of their areas from 1979 to 2000. At least two glaciers already have some stagnant parts and may disappear if the present climatic warming trend in the region persists.
