Collaborative Research: Norwegian-United States IPY Scientific Traverse: Climate Variability and Glaciology in East Antarctica
Entry ID:
liston_0537532
Summary
Abstract:
This award supports a project of scientific investigations along two overland traverses in East Antarctica: one going from the Norwegian Troll Station (72deg. S, 2deg. E) to the United States South Pole Station (90deg. S, 0deg. E) in 2007-2008; and a return traverse starting at South Pole Station and ending at Troll Station by a different route in 2008-2009. This dataset includes surface roughness measurements made along the traverse route.
Purpose: The project will investigate climate change in East Antarctica, with the goals of understanding climate variability in Dronning Maud Land of East Antarctica on time scales of years to centuries and determining the surface and net mass balance of the ice sheet in this sector to understand its impact on sea level. The project will also investigate the impact of atmospheric and oceanic variability and human activities on the chemical composition of firn and ice in the region, and will revisit areas and sites first explored by traverses in the 1960's, for detection of possible changes and to establish benchmark datasets for future research efforts.

Quality
The accuracy and precision of the DEM is not adequate for the detection of real ice surface elevation changes over time, and thus the DEM should not be used for such purposes. Additional processing would be necessary before the DEM could be used as part of a scheme for elevation change detection.
Access Constraints
This data set is available for non-profit, research-oriented purposes only. Prospective users of the product are required to complete a Research Agreement stating that the image and elevation data will be only be used under the specified terms and conditions.
