TL;DR: In this article, 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 embayed ice fronts, calving of myriad small elongate bergs in punctuated events, increasing flow speed, and the presence of melt ponds on the ice-shelf surface in the vicinity of the breakups.

TL;DR: Remote sensing data is used to measure the velocity of Jakobshavn Isbræ to indicate that fast-flowing glaciers can significantly alter ice discharge at sub-decadal timescales, with at least a potential to respond rapidly to a changing climate.

TL;DR: In this article, the authors presented digital image mosaics of surface morphology and optical snow grain size for the Antarctic continent and surrounding islands, assembled from 260 Moderate-resolution Imaging Spectroradiometer (MODIS) images.

TL;DR: Boreholes drilled to the bottom of ice stream B in the West Antarctic Ice Sheet reveal that the base of the ice stream is at the melting point and the basal water pressure is within about 1.6 bars of theIce overburden pressure, allowing the rapid ice streaming motion to occur by basal sliding or by shear deformation of unconsolidated sediments.

TL;DR: In this paper, the authors used time-lapse imagery, seismic and audio recordings, iceberg and glacier velocities, ocean wave measurements, and simple theoretical considerations to investigate the interactions between Jakobshavn Isbrae and its proglacial ice melange.
