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
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
Continental scale, high order, high spatial resolution, ice sheet modeling using the Ice Sheet System Model (ISSM)
Ice flow models used to project the mass balance of ice sheets in Greenland and Antarctica usually rely on the Shallow Ice Approximation (SIA) and the Shallow-Shelf Approximation (SSA), sometimesExpand
A mass conservation approach for mapping glacier ice thickness
The traditional method for interpolating ice thickness data from airborne radar sounding surveys onto regular grids is to employ geostatistical techniques such as kriging. While this approachExpand
BedMachine v3: Complete Bed Topography and Ocean Bathymetry Mapping of Greenland From Multibeam Echo Sounding Combined With Mass Conservation
Abstract Greenland's bed topography is a primary control on ice flow, grounding line migration, calving dynamics, and subglacial drainage. Moreover, fjord bathymetry regulates the penetration of warmExpand
Ice-sheet model sensitivities to environmental forcing and their use in projecting future sea level (the SeaRISE project)
Abstract Ten ice-sheet models are used to study sensitivity of the Greenland and Antarctic ice sheets to prescribed changes of surface mass balance, sub-ice-shelf melting and basal sliding. ResultsExpand
Ice Sheet Model Intercomparison Project (ISMIP6) contribution to CMIP6.
The Ice Sheet Model Intercomparison Project for CMIP6 (ISMIP6) is the primary activity within the Coupled Model Inter Combination Project - phase 6 focusing on the Greenland and Antarctic Ice Sheets. Expand
Spatial patterns of basal drag inferred using control methods from a full-Stokes and simpler models for Pine Island Glacier,
[1] Basal drag is a fundamental control on ice stream dynamics that remains poorly understood or constrained by observations. Here, we apply control methods on ice surfacevelocities ofPineExpand
A synthesis of the basal thermal state of the Greenland Ice Sheet.
The basal thermal state of an ice sheet (frozen or thawed) is an important control upon its evolution, dynamics and response to external forcings. However, this state can only be observed directlyExpand
