MRI-Consortium: Development of a Greenland Ice Sheet Monitoring Network

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。在这个由主要研究仪器（MRI）计划资助的项目中，PI？我们将为格陵兰岛开发一个新的国际（8个国家）宽带地震能力——格陵兰冰盖监测网络（GLISN）——一个由25个站点组成的实时传感器阵列，它增强和升级了格陵兰岛现有稀缺的地震基础设施的性能，用于探测、定位和表征冰川地震和其他低温地震现象，并有助于我们对冰盖动力学的理解。与卫星、大地测量学和其他来源的数据相辅相成，GLISN为观察变化提供了一个强大的工具，并将在冰川系统、影响格陵兰冰盖的潜在地质和地球物理过程、海洋、气候和冰冻圈之间的相互作用以及其他与地球科学和气候动力学相关的多学科领域推进新的研究前沿。遥测基础设施的发展将这些站点连接在一起，形成一个连贯的框架，为快速科学反应创造了时间解析能力和潜力。GLISN是针对一个具有全球重要性的问题开展的国际合作。参与国包括美国、丹麦、加拿大、德国、挪威、瑞士、意大利和日本。GLISN创建了一个新的大型、免费和公开的实时数据集，以加强现有的监测工作，促进新的跨学科科学研究和教育，同时为促进格陵兰冰川系统的区域化研究建立一个基础参考框架。GLISN数据将从具有重要社会意义的区域推进对固体地球和低温震源机制的理解。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). In this project funded by the Major Research Instrumentation (MRI) Program, the PI?s will develop a new, international (8-nation), broadband seismic capability for Greenland - the GreenLand Ice Sheet monitoring Network (GLISN) - a real-time sensor array of 25 stations which enhances and upgrades the performance of the scarce existing Greenland seismic infrastructure for detecting, locating, and characterizing glacial earthquakes and other cryo-seismic phenomena, and contributing to our understanding of Ice Sheet dynamics. Complementing data from satellites, geodesy, and other sources, in concert with these technologies GLISN provides a powerful tool for seeing change, and will advance new frontiers of research in the glacial systems, the underlying geological and geophysical processes affecting the Greenland Ice Sheet, interactions between oceans, climate, and the cryosphere, and other multidisciplinary areas of interest to geoscience and climate dynamics. The development of the telemetry infrastructure linking the sites together into a coherent framework creates the temporal resolving capability and potential for rapid scientific response.GLISN is an international collaboration on a problem of global importance. Participating countries include the USA, Denmark, Canada, Germany, Norway, Switzerland, Italy, and Japan. GLISN creates a new large, freely and openly available, real-time data set to enhance existing monitoring efforts and catalyze new interdisciplinary scientific research and education while establishing a fiducial reference framework for facilitating regionalized studies of Greenland glacial systems. GLISN data will advance understanding of the solid Earth and cryo-seismic source mechanisms from a region of important societal relevance.
