This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This award provides funds to build 20 new seafloor magneto telluric (MT) instruments using fluxgate magnetometer technology. The instruments will be designed and built for deployment offshore Cascadia as part of the proposed onshore-offshore seismic effort. Land-based MT data already exist through the Earthscope program, and PI Evans is funded to collect a more detailed MT profile in Washington State, coincident with a large seismic experiment. The instruments will reside at WHOI but their use will eventually be open to the community.Broader Impacts:This project will involve persons with disabilities by collaborating with CapeAbilities, a non-profit organization on Cape Cod, to have its clients assist in the manufacture of the sensor electrodes. Additionally, the research enabled by these instruments will have direct societal relevance in that the seismogenic zone of Cascadia represents a significant geologic hazard in a highly populated region of North America. The proponents also express a strong desire to entrain new students into the MT field, which has been criticized as lagging behind other countries.

该奖项根据 2009 年美国复苏和再投资法案（公法 111-5）提供资金。该奖项提供资金用于使用磁通门磁力计技术建造 20 台新型海底大地磁 (MT) 仪器。 这些仪器将设计和制造用于部署在卡斯卡迪亚海上，作为拟议的陆上-海上地震工作的一部分。通过 Earthscope 计划，陆基大地电磁数据已经存在，PI Evans 获得资助，在华盛顿州收集更详细的大地电磁剖面图，与大型地震实验同时进行。这些工具将驻留在 WHOI，但它们的使用最终将向社区开放。 更广泛的影响：该项目将通过与科德角非营利组织 CapeAbilities 合作让残疾人参与，让其客户协助制造传感器电极。 此外，这些仪器进行的研究将具有直接的社会意义，因为卡斯卡迪亚的地震带代表了北美人口稠密地区的重大地质灾害。 支持者还表达了吸引新学生进入机器翻译领域的强烈愿望，该领域被批评为落后于其他国家。
