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. The GEOICE's components 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.

智力优势：人们对冰覆盖地区的冰动力学和构造历史知之甚少。对这些地区的科学调查受到极端天气和复杂后勤支持的阻碍。该计划建议为冰盖地区建立一个新的、快速部署、密集覆盖区的地震观测站，即冰盖环境地球物理观测站。这个地震阵列将提供更高的观测能力和后勤效率，以便对固体地球和偏远冰盖地区覆冰的结构和动态行为进行地震成像。GEOICE的组件将被设计为能够承受冰冷和/或潮湿的环境，并需要最少的物流。GEOICE支持的研究包括：冰量和海平面变化，固体地球结构，构造和冰盖稳定性，以及地球深部结构和过程。更广泛的影响：GEOICE将提供一个社区工具，用于更好地了解地球快速变化的极地和冰盖地区。政府间气候变化专门委员会2007年的报告得出结论，对冰川动态的理解不足，阻碍了对未来海平面的可靠估计。GEOICE将开展有助于解决这一社会相关问题的研究。GEOICE简化的物流可以降低阻碍极地地区年轻研究人员的技术和物流障碍。
