Pattern of retreat and disintegration of the Larsen B ice shelf, Antarctic Peninsula
The retreat of the Larsen B ice shelf, Antarctic Peninsula, and the collapse of its northern section are analyzed using satellite images acquired between January 1995 and May 2003. Over 1week during March 2002, after a period of steady retreat since 1995, 2300 km of the ice shelf broke up into many small icebergs. This rapid collapse occurred at the end of an exceptionally warm summer, and afte...
متن کاملThe imbalance of glaciers after disintegration of Larsen-B ice shelf, Antarctic Peninsula
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 TerraSAR-X satellite, launched in June 2007, to map the motion of outlet glaciers in detail. The frontal velocities are used to estimate the calving fluxes for 2008/2009. As reference for pre-collapse conditions...
متن کاملPresent stability of the Larsen C ice shelf, Antarctic Peninsula
We modelled the flow of the Larsen C and northernmost Larsen D ice shelves, Antarctic Peninsula, using a model of continuum mechanics of ice flow, and applied a fracture criterion to the simulated velocities to investigate the ice shelf’s present-day stability. Constraints come from satellite data and geophysical measurements from the 2008/09 austral summer. Ice-shelf thickness was derived from...
متن کاملAccelerated ice discharge from the Antarctic Peninsula following the collapse of Larsen B ice shelf
[1] 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 threefo...
متن کاملCommunity dynamics of nematodes after Larsen ice‐shelf collapse in the eastern Antarctic Peninsula
Free-living marine nematode communities of the Larsen B embayment at the eastern Antarctic Peninsula were investigated to provide insights on their response and colonization rate after large-scale ice-shelf collapse. This study compares published data on the post-collapse situation from 2007 with new material from 2011, focusing on two locations in the embayment that showed highly divergent com...
