This project develops a system of airborne instruments to explore the polar ice sheets and their underlying environments. The instrument suite includes an ice-penetrating radar, laser altimeter, gravimeter and magnetometer. Airborne geophysical measurements are key to understanding the 99% of Antarctica and 85% of Greenland covered by ice, which have thus far been studied at the postage stamp level. Projects linking ice sheet behavior to underlying geology will immediately benefit from this system, but even more exciting are the system's potential uses for work at the frontiers of polar science, such as: 1) exploring subglacial lakes, recently discovered and potentially the most unique sites on Earth for understanding life in extreme environments; 2) locating the deepest, oldest ice, which would offer million year and older samples of the atmosphere; and 3) interpreting Antarctica's subglacial geology, which contains unique and unstudied volcanoes, mountains, and tectonic provinces.In terms of broader impacts, this project constructs research infrastructure critical to society's understanding of sea level rise, and supports a project involving domestic, international, and private sector collaborations.

该项目开发了一套空中仪器系统，用于探测极地冰盖及其下面的环境。该仪器套件包括一台穿冰雷达、激光高度计、重力仪和磁强计。航空地球物理测量是了解南极洲99%和格陵兰85%被冰覆盖的关键，到目前为止，这些研究都是在邮资水平上进行的。将冰盖行为与底层地质联系起来的项目将立即从这个系统中受益，但更令人兴奋的是该系统在极地科学前沿的潜在工作用途，例如：1)探索冰下湖泊，这些湖泊是最近发现的，可能是地球上最独特的地点，用于了解极端环境中的生命；2)定位最深、最古老的冰，这将提供数百万年及更古老的大气样本；3)解释南极的冰下地质，其中包括独特的和未被研究的火山、山脉和构造省。从更广泛的影响来看，该项目构建了对社会理解海平面上升至关重要的研究基础设施，并支持一个涉及国内、国际和私营部门合作的项目。
