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.

TL;DR: There is good agreement between different satellite methods—especially in Greenland and West Antarctica—and that combining satellite data sets leads to greater certainty, and the mass balance of Earth’s polar ice sheets is estimated by combining the results of existing independent techniques.

Antarctic ice-sheet loss driven by basal melting of ice shelves
Hamish D. Pritchard,Stefan R. M. Ligtenberg,Helen A. Fricker,David G. Vaughan,M. R. van den Broeke,Laurie Padman +5 more
TL;DR: Satellite laser altimetry and modelling of the surface firn layer are used to reveal the circum-Antarctic pattern of ice-shelf thinning through increased basal melt, which implies that climate forcing through changing winds influences Antarctic ice-sheet mass balance, and hence global sea level, on annual to decadal timescales.
Journal ArticleDOI
Extensive dynamic thinning on the margins of the Greenland and Antarctic ice sheets
TL;DR: In this paper, a high-resolution ICESat (Ice, Cloud and land Elevation Satellite) laser altimetry is used to map changes along these ocean margins; the results show that dynamic thinning is more important and extensive than previously thought.
