Interferometric synthetic‐aperture radar data collected by ERS‐1/2 and Radarsat‐1 satellites show that Antarctic Peninsula glaciers sped up significantly following the collapse of Larsen B ice shelf in 2002. Hektoria, Green and Evans glaciers accelerated eightfold between 2000 and 2003 and decelerated moderately in 2003. Jorum and Crane glaciers accelerated twofold in early 2003 and threefold by the end of 2003. In contrast, Flask and Leppard glaciers, further south, did not accelerate as they…

Time series of satellite radar image data of Envisat ASAR were used to study the retreat of ice shelves and glaciers at northern Larsen Ice Shelf,Antarctic Peninsula, up to March 2007. After the
Evolution of surface velocities and ice discharge of Larsen B outlet glaciers from 1995 to 2013
We use repeat-pass SAR data to produce detailed maps of surface motion covering the glaciers draining into the former Larsen B Ice Shelf, Antarctic Peninsula, for different epochs between 1995 and

Satellite radar interferometry data from 1995 to 2004, and airborne ice thickness data from 2002, reveal that the glaciers flowing into former Wordie Ice Shelf, West Antarctic Peninsula, discharge
Antarctic ice-shelf advance driven by anomalous atmospheric and sea-ice circulation
The disintegration of the eastern Antarctic Peninsula’s Larsen A and B ice shelves has been attributed to atmosphere and ocean warming, and increased mass losses from the glaciers once restrained by
Detailed ice loss pattern in the northern Antarctic Peninsula: widespread decline driven by ice front retreats
The northern Antarctic Peninsula (nAP, < 66 S) is one of the most rapidly changing glaciated regions on earth, yet the spatial patterns of its ice mass loss at the glacier basin scale have to date

The concept that the Antarctic ice sheet changes with eternal slowness has been challenged by recent observations from satellites, and sectors grounded well below sea level, such as Cook Ice Shelf, Ninnis/Mertz, Frost and Totten glaciers, are thinning and losing mass.
Recent ice-surface-elevation changes of Fleming Glacier in response to the removal of the Wordie Ice Shelf, Antarctic Peninsula
Abstract Regional climate warming has caused several ice shelves on the Antarctic Peninsula to retreat and ultimately collapse during recent decades. Glaciers flowing into these retreating ice
The imbalance of glaciers after disintegration of Larsen-B ice shelf, Antarctic Peninsula
Abstract. The outlet glaciers to the embayment of the Larsen-B Ice Shelf started to accelerate soon after the ice shelf disintegrated in March 2002. We analyse high resolution radar images of the
Oceanic and atmospheric forcing of Larsen C Ice-Shelf thinning
Abstract. The catastrophic collapses of Larsen A and B ice shelves on the eastern Antarctic Peninsula have caused their tributary glaciers to accelerate, contributing to sea-level rise and freshening


Northern Larsen Ice Shelf, Antarctica: further retreat after collapse
Abstract Changes of Larsen Ice Shelf, Antarctica, and the surrounding glaciers after its collapse in 1995 were investigated using satellite radar imagery, with emphasis on changes in the glaciers
Improved estimation of the mass balance of glaciers draining into the Amundsen Sea sector of West Antarctica from the CECS/NASA 2002 campaign
Abstract In November–December 2002, a joint airborne experiment by Centro de Estudios Cientifícos and NASA flew over the Antarctic ice sheet to collect laser altimetry and radio-echo sounding data
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.
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.
Force-perturbation analysis of Pine Island Glacier, Antarctica, suggests cause for recent acceleration
Abstract Pine Island Glacier, flowing into the Amundsen Sea from West Antarctica, thinned substantially during the 1990s, its grounding line receded by several km, and its velocity increased by >10%
Dynamic Behavior and Disintegration of the Northern Larsen Ice Shelf, Antarctic Peninsula
The dynamic behavior and retreat of the northern Larsen Ice Shelf, Antarctic Peninsula, and its relation to climatic parameters areinvestigated. The analysis concentrates on the period after 1986 and
The link between climate warming and break-up of ice shelves in the Antarctic Peninsula
Abstract A review of in situ and remote-sensing data covering the ice shelves of the Antarctic Peninsula provides a series of characteristics closely associated with rapid shelf retreat: deeply
West Antarctic Ice Streams
Solar heat is the acknowledged driving force for climatic change. However, ice sheets are also capable of causing climatic change. This property of ice sheets derives from the facts that ice and rock

New calculations were performed to investigate the combined response of the Greenland and Antarctic ice sheets to a range of climatic warming scenarios over the next millennium. Use was made of fully
