Ice-Shelf Melting Around Antarctica
Major Meltdown The ice shelves and floating ice tongues that surround Antarctica cover more than 1.5 million square kilometers—approximately the size of the entire Greenland Ice Sheet. ConventionalExpand

Bedmap2: improved ice bed, surface and thickness datasets for Antarctica
We present Bedmap2, a new suite of gridded products describing surface elevation, ice-thickness and the seafloor and subglacial bed elevation of the Antarctic south of 60° S. We derived theseExpand

Ice Flow of the Antarctic Ice Sheet
A high-resolution map of ice motion in Antarctica shows the details of ice movement in a warming climate. We present a reference, comprehensive, high-resolution, digital mosaic of ice motion inExpand

A Reconciled Estimate of Ice-Sheet Mass Balance
Warming and Melting Mass loss from the ice sheets of Greenland and Antarctica account for a large fraction of global sea-level rise. Part of this loss is because of the effects of warmer airExpand

A new bed elevation dataset for Greenland
Abstract. We present a new bed elevation dataset for Greenland derived from a combination of multiple airborne ice thickness surveys undertaken between the 1970s and 2012. Around 420 000 lineExpand

Antarctic grounding line mapping from differential satellite radar interferometry
[1] The delineation of an ice sheet grounding line, i.e., the transition boundary where ice detaches from the bed and becomes afloat in the ocean, is critical to ice sheet mass budget calculations,Expand

Widespread, rapid grounding line retreat of Pine Island, Thwaites, Smith, and Kohler glaciers, West Antarctica, from 1992 to 2011
We measure the grounding line retreat of glaciers draining the Amundsen Sea sector of West Antarctica using Earth Remote Sensing (ERS-1/2) satellite radar interferometry from 1992 to 2011. PineExpand

Ice flow in Greenland for the International Polar Year 2008-2009
A digital representation of ice surface velocity is essential for a variety of glaciological, geologic and geophysical analyses and modeling. Here, we present a new, reference, comprehensive,Expand

Deeply incised submarine glacial valleys beneath the Greenland ice sheet
The bed topography beneath the Greenland ice sheet controls the flow of ice and its discharge into the ocean. A combination of sparse radar soundings of ice thickness and high-resolution ice motionExpand

Four decades of Antarctic Ice Sheet mass balance from 1979–2017
Significance Statement We evaluate the state of the mass balance of the Antarctic Ice Sheet over the last four decades using a comprehensive, precise satellite record and output products from aExpand
