The continued retreat of ice shelves on the Antarctic Peninsula has been widely attributed to recent atmospheric warming, but there is little published work describing changes in glacier margin positions. We present trends in 244 marine glacier fronts on the peninsula and associated islands over the past 61 years. Of these glaciers, 87% have retreated and a clear boundary between mean advance and retreat has migrated progressively southward. The pattern is broadly compatible with retreat driven… 

Ice Scour Disturbance in Antarctic Waters

It is shown that the annual intensity of ice scouring is negatively correlated with the duration of the winter fast ice season, and it is likely that marine benthic communities are set for even more scouring in the near future.

Collins Glacier Retreat Process and Regional Climatic Variations, King George Island, Antarctica

Abstract This paper investigates the recent climatic variability and changes in snow line and ice front position in Collins Glacier, King George Island, South Shetland Islands, Antarctic Peninsula.

Reduced ice extent on the western Antarctic Peninsula at 700–970 cal. yr B.P.

Rapid warming and consequent ice-shelf collapse have focused attention on the glacial record of the Antarctic Peninsula. Here, we present the first record of terrestrial organic material exposed by

Synchronous terminus change of East Antarctic outlet glaciers linked to climatic forcing

In recent years there has been a growing trend of acceleration, thinning and retreat of ocean-terminating outlet glaciers in both the Greenland and West Antarctic Ice Sheets, resulting in an

Ocean forcing of glacier retreat in the western Antarctic Peninsula

It is concluded that changes in ocean-induced melting are the primary cause of retreat for glaciers in this region and a mid-ocean warming since the 1990s in the south is coincident with widespread acceleration of glacier retreat.

Rapid, climate-driven changes in outlet glaciers on the Pacific coast of East Antarctica

It is found that glacier change along the Pacific coast is consistent with a rapid and coherent response to air temperature and sea-ice trends, linked through the dominant mode of atmospheric variability (the Southern Annular Mode), and that parts of the world’s largest ice sheet may be more vulnerable to external forcing than recognized previously.

Fluctuation of Glacial Retreat Rates in the Eastern Part of Warszawa Icefield, King George Island, Antarctica, 1979-2018

Assessment of changes in glacier margin positions between 1979 and 2018 in the Antarctic Specially Protected Area 128 (ASPA-128) on King George Island, South Shetland Islands, Antarctica suggests that glacier retreat rates were fastest between 1989–2001 and 2007–2011, with reduced retreat rates between 2001 and 2007.

The Cryosphere Overview of areal changes of the ice shelves on the Antarctic Peninsula over the past 50 years

In recent decades, seven out of twelve ice shelves around the Antarctic Peninsula (AP) have either retreated significantly or have been almost entirely lost. At least some of these retreats have been

Pan–ice-sheet glacier terminus change in East Antarctica reveals sensitivity of Wilkes Land to sea-ice changes

An approximately decadal record of outlet-glacier terminus position change around the entire East Antarctic Ice Sheet (EAIS) marine margin finds that most outlet glaciers retreated during the period 1974–1990, before switching to advance during the two most recent periods, 1990–2000 and 2000–2012.

Recent atmospheric warming and retreat of ice shelves on the Antarctic Peninsula

IN 1978 Mercer1 discussed the probable effects of climate warming on the Antarctic Ice Sheet, predicting that one sign of a warming trend in this region would be the retreat of ice shelves on the

Larsen Ice Shelf Has Progressively Thinned

Satellite radar altimeter measurements show that between 1992 and 2001 the Larsen Ice Shelf lowered by up to 0.27 ± 0.11 meters per year, suggesting enhanced ocean-driven melting may provide a simple link between regional climate warming and the successive disintegration of sections of the Larsan Ice She shelf.

First survey of Antarctic sub–ice shelf sediments reveals mid-Holocene ice shelf retreat

The retreat of five small Antarctic Peninsula ice shelves in the late 20th century has been related to regional (possibly anthropogenic) climate warming. We use the record of ice- rafted debris (IRD)

In January 1995, 4200 square kilometers of the northern Larsen Ice Shelf, Antarctic Peninsula, broke away. Radar images from the ERS-1 satellite, complemented by field observations, showed that the

Glacier Surge After Ice Shelf Collapse

Evidence is presented here showing drastic dynamic perturbations on former tributary glaciers that fed sections of the Larsen Ice Shelf on the Antarctic Peninsula before its collapse in 1995, prompting reconsideration of former hypotheses about the stabilizing role of ice shelves.
