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.

0538495阿尔伯特该奖项支持科学调查项目沿沿着两个陆上横贯南极洲东部：一个从挪威巨魔站（72度。S，2度。美国南极站（90度）S，0度。2008 - 2009年，从南极站开始，以另一条路线在巨魔站结束的回程。 该项目将调查东南极洲的气候变化，目的是了解东南极洲德龙宁毛德地在几年至几个世纪的时间尺度上的气候变化，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的变化以及人类活动对该地区的积雪和冰的化学成分的影响，并将重新访问1960年代首次进行穿越勘探的地区和地点，以检测可能的变化，并为未来的研究工作建立基准数据集。 就更广泛的影响而言，这项研究的结果将增加对南极洲东部气候变异及其对全球海平面变化的影响的了解。该项目包括有关机构之间的研究生国际交流，以及通过斯瓦尔巴特群岛联合国新闻处PI教授的课程对本科生进行国际教育。它涉及通过报刊、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进行广泛宣传。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的积极知识共享和合作，为探索半个世纪以来东南极洲气候代理，科学工具以及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有关，因为它是国家之间的真正合作：参与的科学家拥有互补的专业知识，所涉及的后勤工作依赖于每个国家特有的资产。这确实是任何一个国家都无法单独完成的奋进。 该项目是东南极洲冰分水岭跨南极科学考察（TASTE-IDEA）的一部分，该项目也是国际极地年的一部分。
