IPY Research: Investigating the Cryospheric Evolution of the Central Antarctic Plate (ICECAP)

该项目是一项航空地球物理调查，旨在探索南极洲东部的未知地形，以回答气候变化和地球科学问题。这些方法包括穿冰雷达、重力和磁测量。这个项目吗?科考小组的主要目标是调查引导南极东部冰盖流动的冰的稳定性和迁移。最大的。该项目还绘制了最后一次间冰期的冰积累图，确定了冰下湖泊，并描绘了包括威尔克斯和奥罗拉在内的最大冰川盆地的集水区。这些结果有助于建立与了解全球变暖情况下海平面上升相关的冰盖模型。这项工作还将有助于了解该地区的地质情况。东南极洲被埋在数英里厚的冰层之下，几乎没有任何特征，但被认为是构造重建和其他地质问题的基石。该地区还拥有冰下湖泊，其地质历史尚不清楚。更广泛的影响是广泛的，包括了解海平面上升的社会意义，各种形式的推广，以及从K12到博士后水平的教育。该项目为国际极地年（2007-2009）做出了贡献，解决了极地年关于极地探索前沿和气候变化的关键主题。它还包括与英国、澳大利亚、法国和其他国家的广泛国际合作；并为早期职业科学家提供了明确的机会。

This project is an aerogeophysical survey to explore unknown terrain in East Antarctica to answer questions of climate change and earth science. The methods include ice-penetrating radar, gravity, and magnetic measurements. The project?s main goal is to investigate the stability and migration of ice divides that guide flow of the East Antarctic ice sheet, the world?s largest. The project also maps ice accumulation over the last interglacial, identifies subglacial lakes, and characterizes the catchment basins of the very largest glacial basins, including Wilkes and Aurora. The outcomes contribute to ice sheet models relevant to understanding sea level rise in a warming world. The work will also help understand the regional geology. Buried beneath miles-thick ice, East Antarctica is virtually uncharacterized, but is considered a keystone for tectonic reconstructions and other geologic questions. The region also hosts subglacial lakes, whose geologic histories are unknown. The broader impacts are extensive, and include societal relevance for understanding sea level rise, outreach in various forms, and education at the K12 through postdoctoral levels. The project contributes to the International Polar Year (2007-2009) by addressing key IPY themes on frontiers in polar exploration and climate change. It also includes extensive international collaboration with the United Kingdom, Australia, France and other nations; and offers explicit opportunities for early career scientists.
