Intellectual Merit: The ice dynamics and tectonic history of Ice-covered regions are poorly understood. Scientific investigations of these regions are hindered by extreme weather and complex logistical support. The PIs propose development of a new, rapid deployment, dense footprint, seismic observatory for ice-covered regions, the Geophysical Earth Observatory for Ice-Covered Environments (GEOICE). This seismic array will provide increased observational capabilities and logistical efficiencies needed to seismically image the structures and dynamic behavior of both the solid Earth and overlying ice in remote ice-covered regions. Instruments developed for GEOICE will be designed to withstand icy and/or wet environments and require minimal logistics. Research enabled by GEOICE includes: ice mass and sea level changes, solid earth structure, tectonics and ice sheet stability, and deep Earth structure and processes.Broader impacts: GEOICE will provide a community tool for achieving a better understanding of the Earth's rapidly changing polar and ice-covered regions. The Intergovernmental Panel on Climate Change's 2007 report concluded that poor understanding of glacial dynamics prohibits robust estimates of future sea-level. GEOICE will enable research that helps address this societally relevant issue. Simplified logistics enabled by GEOICE could lower the technical and logistical barriers that hinder young investigators in the polar regions.

知识分子的优点：冰覆盖地区的冰动态和构造历史知之甚少。极端天气和复杂的后勤支持阻碍了对这些地区的科学研究。 PI提出了开发一种新的快速部署，密集的占地面积，冰盖区域的地震天文台，冰覆盖环境的地球物理地球天文台（Geoice）。这种地震阵列将提供提高的观察能力和后勤效率，以在远程冰覆盖的区域中地震图像固体地球和上覆盖冰的结构和动态行为所需。为Geoice开发的仪器将被设计为承受冰冷和/或潮湿的环境，并且需要最少的物流。 Geoice启用的研究包括：冰质量和海平面变化，固体地球结构，构造和冰盖稳定以及深层的结构和过程。BROADER的影响：Geoice将提供一个社区工具，以更好地了解地球快速变化的极性和冰覆盖的地区。政府间气候变化2007年的报告的结论得出结论，对冰川动力学的理解不佳禁止对未来海平面的强大估计。 Geoice将实现有助于解决这个与社会相关问题的研究。地球上支持的简化物流可以降低阻碍极地地区年轻研究人员的技术和后勤障碍。
