George VI Ice Shelf is the largest ice shelf on the west coast of the Antarctic Peninsula, covering a total area of 25 000 km2. The northern ice front of George VI Ice Shelf presently marks the southernmost occurrence of recent ice-shelf retreat on the Antarctic Peninsula and according to some predictions the ice shelf is close to its thermal limit of stability. If these predictions are accurate and we are witnessing the first stages of retreat then it is critical that we take the opportunity… Expand
The Holocene history of George VI Ice Shelf, Antarctic Peninsula
Meteorological records have shown that the Antarctic Peninsula region has warmed at a rate of 3.7 ± 1.6 С during the last century. One of the most publicised aspects of this warming has been theExpand
Changes of Wilkins Ice Shelf over the past 15 years and inferences on its stability
Abstract. The Wilkins Ice Shelf is situated on the Antarctic Peninsula, a region where seven ice shelves disintegrated or retreated between 1995 and 2002. This study combines various remote sensingExpand
Structure and sedimentology of George VI Ice Shelf, Antarctic Peninsula: implications for ice-sheet dynamics and landform development
Collapse of Antarctic ice shelves in response to a warming climate is well documented, but its legacy in terms of depositional landforms is little known. This paper uses remote-sensing, structuralExpand
Oceanic and atmospheric forcing of early Holocene ice shelf retreat, George VI Ice Shelf, Antarctica Peninsula
We use lake sediment records from an epishelf lake on Alexander Island to provide a detailed picture of the Holocene history of George VI Ice Shelf (GVI-IS). Core analyses included; micropaleontologyExpand
Speedup and fracturing of George VI Ice Shelf, Antarctic Peninsula
George VI Ice Shelf (GVIIS) is located on the Antarctic Peninsula, a region where several ice shelves have undergone rapid breakup in response to atmospheric and oceanic warming. We use a combinationExpand

Abstract. George VI Ice Shelf (GVIIS) is located on the Antarctic Peninsula, a region where several ice shelves have undergone rapid breakup in response to atmospheric and oceanic warming. We use aExpand
Changes in Supraglacial Lakes on George VI Ice Shelf, Antarctic Peninsula: 1973–2020
Abstract. High densities of supraglacial lakes have been associated with ice shelf instability and collapse. 2020 was a record melt year on George VI ice shelf with ~12 % of its northernmost portionExpand
Rapid deglaciation of Marguerite Bay, western Antarctic Peninsula in the Early Holocene
Glacial geological evidence of rapid ice stream retreat is important for the potential insight it can bring to understanding of contemporary rapid ice sheet change. Here, we report new chronologicalExpand
Antarctic Peninsula Ice Sheet evolution during the Cenozoic Era
The Antarctic Peninsula region is currently undergoing rapid environmental change, resulting in the thinning, acceleration and recession of glaciers and the sequential collapse of ice shelves. It isExpand
Surface structure and stability of the Larsen C ice shelf, Antarctic Peninsula
A structural glaciological description and analysis of surface morphological features of the Larsen C ice shelf, Antarctic Peninsula, is derived from satellite images spanning the period 1963-2007.Expand
