TL;DR: Bedmap2 as discussed by the authors is a suite of gridded products describing surface elevation, ice-thickness and the seafloor and subglacial bed elevation of the Antarctic south of 60° S. In particular, the Bedmap2 ice thickness grid is made from 25 million measurements, over two orders of magnitude more than were used in Bedmap1.
Journal ArticleDOI
Deformation of till beneath ice stream B, West Antarctica
TL;DR: In this paper, the authors propose that deformation within the till is the primary mechanism by which the ice stream moves, and discuss implications of this hypothesis, and assume that this thin layer occurs well inland beneath an active ice sheet and rests on a surface showing flutes characteristic of glacial erosion.
Journal ArticleDOI
Deep glacial troughs and stabilizing ridges unveiled beneath the margins of the Antarctic ice sheet

TL;DR: In this paper, a high-resolution and physically based description of Antarctica bed topography using mass conservation is presented, revealing previously unknown basal features with major implications for glacier response to climate change.
Journal ArticleDOI
Seismic measurements reveal a saturated porous layer beneath an active Antarctic ice stream
TL;DR: In this article, the authors show that the material in the layer is highly porous and is saturated with water at high pore pressure, and they conclude that the layer deforms and that the ice stream probably moves principally by such deformation.
Journal ArticleDOI
Till beneath ice stream B: 3. Till deformation: Evidence and implications
TL;DR: Most of the velocity of ice stream B near the Upstream B camp (UpB), West Antarctica, appears to arise from deformation of a seismically detected, subglacial till layer that averages 6 m thick as discussed by the authors.
