Norwegian-U.S. Scientific Traverse of East Antarctica
Project DescriptionA massive, largely unexplored region, the East Antarctic ice sheet looms large in the global climate system, yet relatively little is known about its climate variability or the contribution it makes to sea level changes. The field expedition for this international partnership involves scientific investigations along two overland traverses in East Antarctica: one going from the Norwegian Troll Station to the United States South Pole Station in 2007-2008; and a return traverse by a different route in 2008-2009. This project will investigate climate change in East Antarctica, with the following goals:
* Investigate climate variability in Dronning Maud Land of East Antarctica on time scales of years to a million years.
* Establish spatial and temporal variability in snow accumulation over this area of Antarctica to understand its impact on sea level.
* Investigate the impact of atmospheric and oceanic variability on the chemical composition of firn and ice in the region.
* Revisit areas and sites first explored by traverses in the 1960’s, for detection of possible changes and to establish benchmark data sets for future research efforts.
