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.

该奖项支持对埋葬在南极洲东部冰盖下方的得克萨斯州大小的山脉Gamburtsev亚冰山山（GSM）的航空地球物理研究。该项目将执行重力，磁性和雷达研究，以实现一系列目标，包括：促进我们对极地冰片和冰山下湖泊的起源和进化的理解；定义东南极洲东部的地壳建筑，这是地球历史上的关键问题；并找到南极洲东部最古老的冰，最终可能有助于找到古老的气候记录。 GSM几乎没有探索，代表了地球上地壳升高的最大未研究区域。同样，该地区也是南极冰盖生长的起点。由于这些杰出的问题，国际南极科学界已经确定了GSM是国际极性年（2007-2009）的研究重点。除这项研究外，NSF还支持对GSM的地震学调查，该奖项根据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，以及各种形式的外展活动，包括关注地球科学中代表性不足的群体。
