متن کاملHolocene evolution of the western Greenland Ice Sheet: Assessing geophysical ice-sheet models with geological reconstructions of ice-margin change
Geophysical ice-sheet models are used to predict future ice-sheet dimensions and, in turn, these projections help estimate the magnitude of eustatic sea-level rise. Before models can confidently predict icesheet behavior, they must be validated by being able to duplicate the geological record of ice-sheet change. Here, we review geological records of Greenland Ice Sheet (GrIS) change, with emph...
متن کاملA new ice thickness and bedrock dataset for the Greenland ice sheet
Ice thickness data collected between 1993 and 1999 using a coherent ice penetrating radar system developed at the University of Kansas have been combined with data collected by the Technical University of Denmark in the 1970s to produce a new ice thickness grid for Greenland. Cross-over analysis was used to assess the relative accuracy of the two datasets and they were weighted accordingly and ...
متن کاملMicrobial abundance in surface ice on the Greenland Ice Sheet
Measuring microbial abundance in glacier ice and identifying its controls is essential for a better understanding and quantification of biogeochemical processes in glacial ecosystems. However, cell enumeration of glacier ice samples is challenging due to typically low cell numbers and the presence of interfering mineral particles. We quantified for the first time the abundance of microbial cell...
متن کاملRadar Measurements of Ice Sheet Thickness of Outlet Glaciers in Greenland
We have conducted airborne measurements over the Greenland ice sheet from the NASA P-3B aircraft using a 150MHz coherent radar depth sounder to obtain extensive ice sheet thickness measurements. Simultaneous measurements of ice sheet elevation were also made using a laser altimeter. In outlet glacier areas along the ice sheet margin, the ice surface is characterized by a very rough, crevassed s...
