MRI: Acquisition of Broadband Seismic Stations for Polar Regions

该项目获得了一组35台地震仪器，设计用于在极冷（零下55摄氏度）的深层油田工作。这些地震仪将用于在南极和北极的各种野外实验中进行冬季测量。就智力价值而言，这些设备所做的观察将帮助我们理解和模拟冰盖对全球变暖的反应，并改善我们从地壳到地核对地球的看法。就更广泛的影响而言，这个项目代表了新的、前所未有的研究基础设施。这些仪器将由大学地震学联合会IRIS获得和管理，并将提供给一般科学界用于极地工作。这些仪器将在国际极地年（2007-2009）期间立即用于美国的旗舰项目。

This project acquires a pool of thirty-five seismic instruments designed to operate in the deep field in extreme cold, down to minus 55 degrees centigrade. These seismometers will be used to make winter measurements in various field experiments in the Antarctic and Arctic. In terms of intellectual merit, observations made by these devices will help us understand and model ice sheet behavior in response to global warming and improve our view of the earth from crust to core. In terms of broader impacts, this project represents new, never before available research infrastructure. The instruments will be acquired and managed by IRIS, the university consortium for seismology, and will be made available to the general scientific community for polar work. The instruments will see immediate use for US flagship projects during the International Polar Year (2007-2009).
