Journal ArticleDOI
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
Volume loss from Antarctic ice shelves is accelerating
TL;DR: Satellite data is presented showing that ice shelves in many regions around the edge of Antarctica are losing mass, which increases concern about how fast sea level might rise as climate continues to warm.
Journal ArticleDOI
The Ice, Cloud, and land Elevation Satellite-2 (ICESat-2): Science requirements, concept, and implementation
Thorsten Markus,Thomas Neumann,Anthony J. Martino,Waleed Abdalati,Kelly M. Brunt,Beata Csatho,Sinead L. Farrell,Helen A. Fricker,Alex S. Gardner,David J. Harding,Michael F. Jasinski,Ron Kwok,Lori A.

Schutz,Benjamin Smith,Yuekui Yang,Yuekui Yang,Jay Zwally +25 more
TL;DR: The ICESat-2 mission is a follow-on to the ICES-1 mission with three pairs of beams, each pair separated by about 3 km cross-track with a pair spacing of 90 m as discussed by the authors.
Journal ArticleDOI
An Active Subglacial Water System in West Antarctica Mapped from Space
TL;DR: Satellite laser altimeter elevation profiles from 2003 to 2006 collected over the lower parts of Whillans and Mercer ice streams reveal 14 regions of temporally varying elevation, which are interpreted as the surface expression of subglacial water movement.
Journal ArticleDOI
The ICESat-2 Laser Altimetry Mission

TL;DR: NASA's Ice, Cloud and Land Elevation Satellite-2 (ICESat-2), currently planned for launch in 2015, is specifically intended to quantify the amount of change in ice sheets and sea ice and provide key insights into their behavior through the use of precise laser measurements of surface elevation.
