Collaborative Research: IPY: GAMBIT: Gamburtsev Aerogeophysical Mapping of Bedrock and Ice Targets

该奖项支持对甘布尔采夫冰下山脉(GSM)的航空地球物理研究，这是一个埋在东南极冰盖下的德克萨斯州大小的山脉。该项目将进行重力、磁学和雷达相结合的研究，以实现一系列目标，包括：促进我们对极地冰盖和冰下湖泊起源和演化的理解；确定东南极的地壳结构，这是地球历史上的一个关键问题；以及定位东南极最古老的冰，这最终可能有助于发现古代气候记录。GSM几乎没有被开发过，它代表了地球上最大的未被研究的地壳隆起区域。此外，该地区也是南极冰盖生长的起点。由于这些悬而未决的问题，全球定位系统已被国际南极科学界确定为国际极地年(2007-2009年)的研究重点。除了这项研究外，美国国家科学基金会还支持对全球移动通信系统进行的一项地震调查，获奖号为0537371。该项目的主要国际合作伙伴包括德国、中国、澳大利亚和英国。有关更多信息，请参见IPY.org上的IPY项目#67。在更广泛的影响方面，该项目还支持博士后和研究生研究，以及各种形式的宣传，包括重点关注地球科学中代表性不足的群体。

This award supports an aerogeophysical study of the Gamburtsev Subglacial Mountains (GSM), a Texas-sized mountain range buried beneath the ice sheets of East Antarctica. The project would perform a combined gravity, magnetics, and radar study to achieve a range of goals including: advancing our understanding of the origin and evolution of the polar ice sheets and subglacial lakes; defining the crustal architecture of East Antarctica, a key question in the earth's history; and locating the oldest ice in East Antarctica, which may ultimately help find ancient climate records. Virtually unexplored, the GSM represents the largest unstudied area of crustal uplift on earth. As well, the region is the starting point for growth of the Antarctic ice sheets. Because of these outstanding questions, the GSM has been identified by the international Antarctic science community as a research focus for the International Polar Year (2007-2009). In addition to this study, NSF is also supporting a seismological survey of the GSM under award number 0537371. Major international partners in the project include Germany, China, Australia, and the United Kingdom. For more information see IPY Project #67 at IPY.org. In terms of broader impacts, this project also supports postdoctoral and graduate student research, and various forms of outreach including a focus on groups underrepresented in the earth sciences.
