Collaborative Research: Norwegian-United States IPY Scientific Traverse: Climate Variability and Glaciology in East Antarctica

这个奖项支持一个沿着东南极洲两条陆路横贯的科学调查项目：一条从挪威巨魔站（72度）出发。年代,2度。E)到美国南极站（90度）。年代,0度。E) 2007-2008年；2008年至2009年，从南极站开始，以不同的路线在巨魔站结束。该项目将调查东南极洲的气候变化，目标是在数年至数世纪的时间尺度上了解东南极洲的干旱莫德地的气候变化，并确定该地区冰盖的表面和净质量平衡，以了解其对海平面的影响。该项目还将调查大气和海洋变化以及人类活动对该区域冰和冰的化学成分的影响，并将重新考察1960年代首次穿越者探索的地区和地点，以探测可能的变化，并为今后的研究工作建立基准数据集。就更广泛的影响而言，这项研究的结果将有助于了解东南极洲的气候变率及其对全球海平面变化的影响。该项目包括参与机构之间的研究生国际交流，以及通过在斯瓦尔巴群岛UNIS的PI教授的课程对本科生进行国际教育。它包括通过报刊、电视、科学博物馆、儿童文学和网站向斯堪的纳维亚和北美的公众广泛宣传。来自挪威和美国的南极冰川学先驱与参与该项目的国际科学家和学生之间积极的知识共享和合作，为探索半个世纪以来东南极洲气候代用物、科学工具、科学文化和科学人员的变化提供了独特的机会。该项目与国际极地年（IPY）有关，因为它是国家之间的真正合作：参与的科学家具有互补的专业知识，所涉及的后勤依赖于每个国家独特的资产。这确实是一项任何国家都无法单独完成的努力。该项目是跨南极科学穿越考察项目（TASTE-IDEA）的一部分，该项目也是IPY的一部分。

0538495AlbertThis 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. 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. In terms of broader impacts, the results of this study will add to understanding of climate variability in East Antarctica and its contribution to global sea level change. The project includes international exchange of graduate students between the institutions involved and international education of undergraduate students through classes taught by the PI's at UNIS in Svalbard. It involves extensive outreach to the general public both in Scandinavia and North America through the press, television, science museums, children's literature, and web sites. Active knowledge sharing and collaboration between pioneers in Antarctic glaciology from Norway and the US, with the international group of scientists and students involved in this project, provide a unique opportunity to explore the changes that half a century have made in climate proxies from East Antarctica, scientific tools, and the culture and people of science. The project is relevant to the International Polar Year (IPY) since it is a genuine collaboration between nations: the scientists involved have complementary expertise, and the logistics involved relies on assets unique to each nation. It is truly an endeavor that neither nation could accomplish alone. This project is a part of the Trans- Antarctic Scientific Traverse Expeditions Ice Divide of East Antarctica (TASTE-IDEA) which is also part of IPY.
