Elevation changes of ice caps in the Canadian Arctic Archipelago
[1] Precise repeat airborne laser surveys were conducted over the major ice caps in the Canadian Arctic Archipelago in the spring of 1995 and 2000 in order to measure elevation changes in the region.Expand

Force-perturbation analysis of recent thinning and acceleration of Jakobshavn Isbræ, Greenland
Abstract Observations between 1997 and 2001, of a 30% velocity increase and up to 60 m thinning of downstream parts of Jakobshavn Isbræ, Greenland, immediately following calving of about 4 km of itsExpand

Aircraft laser altimetry measurement of elevation changes of the greenland ice sheet: technique and accuracy assessment
Abstract Airborne laser altimetry has been used during the past decade to measure the surface elevation of the Greenland ice sheet. These measurements have been made using a scanning laser on a NASAExpand

Progressive increase in ice loss from Greenland
[1] Laser altimeter measurements over Greenland show increasing thickening rates above 2000 m, reflecting increasing snowfall in a warming climate. But near-coastal thinning rates have increasedExpand

Investigation of surface melting and dynamic thinning on Jakobshavn Isbrae, Greenland
Jakobshavn Isbrae is the most active glacier in Greenland, with an annual discharge of about 30 km 3 of ice, and it is one of the few recently surveyed glaciers to thicken between 1993 and 1998,Expand

Slope‐induced errors in radar altimetry over continental ice sheets
Ranges obtained by radar altimetry from a satellite to a sloping surface on the earth are not measurements of the surface elevation at the subsatellite point. Instead, the reflecting point isExpand

A model for Holocene retreat of the West Antarctic Ice Sheet
Abstract Marine ice sheets are grounded on land which was below sea level before it became depressed under the ice-sheet load. They are inherently unstable and, because of bedrock topography afterExpand
