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.

知识价值：对冰雪覆盖地区的冰动力学和构造历史了解甚少。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。pi建议开发一种新的、快速部署的、密集足迹的、覆盖冰盖地区的地震观测站，即覆盖冰盖环境的地球物理观测站（GEOICE）。该地震阵列将提供更高的观测能力和后勤效率，以便在遥远的冰雪覆盖地区对固体地球和上覆冰的结构和动态行为进行地震成像。为GEOICE开发的仪器将设计成能够承受冰冷和/或潮湿的环境，并且需要最少的物流。GEOICE支持的研究包括：冰块和海平面变化，固体地球结构，构造和冰盖稳定性，以及深层地球结构和过程。更广泛的影响：GEOICE将为更好地了解地球快速变化的极地和冰雪覆盖地区提供一个社区工具。政府间气候变化专门委员会2007年的报告得出的结论是，对冰川动态的不了解妨碍了对未来海平面的可靠估计。GEOICE将使有助于解决这一社会相关问题的研究成为可能。GEOICE简化了后勤工作，可以降低阻碍极地地区青年调查人员的技术和后勤障碍。
