Collaborative Research: High-Resolution Studies Of Glacier Dynamics At Two Major Outlet Glaciers In East Greenland, Gordon S. Hamilton Oct 2012

Collaborative Research: High-Resolution Studies Of Glacier Dynamics At Two Major Outlet Glaciers In East Greenland, Gordon S. Hamilton

University of Maine Office of Research Administration: Grant Reports

The Principal Investigators request support for an interdisciplinary, high-resolution study involving remote sensing and field investigations at two of Greenland's largest outlet glaciers. The study of the Helheim and Kangerdlugssuaq Glaciers will integrate seismological, glaciological, and geodetic observations to build an understanding of flow dynamics at major outlet glaciers, which represent a critical junction between the atmosphere, cryosphere, and hydrosphere. The project would be the first long-term occupation of an outlet glacier by a GPS receiver network, and would address questions of flow variation on earthquake to interannual time scales. Recent discoveries have made it clear that our understanding of …


Ice Dynamics And Surface Glaciology Along Us Itase Traverse Routes In East Antarctica, Gordon Hamilton Jun 2012

Ice Dynamics And Surface Glaciology Along Us Itase Traverse Routes In East Antarctica, Gordon Hamilton

University of Maine Office of Research Administration: Grant Reports

This award supports a series of field measurements that will improve our understanding of the East Antarctic ice sheet. The objectives of this project are to take advantage of the overland traverse logistics framework provided by US ITASE and to collaborate with other US ITASE investigators to calculate rates of ice sheet thickness change (mass balance) on domes, along elevation contours and along flow lines in East Antarctica using precise global positioning system methods. In addition, the variability (both spatial and temporal) in snow accumulation rates will be assessed using shallow ice cores and ground-penetrating radar profiling, and will provide …
