RAPID: Development and Deployment of a Prototype Full Ocean Depth OBS

这一快速提案寻求资金，以便于2013年1月在马里亚纳海沟开发、建造和部署一台原型全海底地震仪(OBS)。目前的OBS仅限于5000-6000米的部署深度，在这些深度或附近部署的少数几个实验的仪器和数据返回率较低。随着最近发生的大海啸俯冲带地震，以及人们对全面覆盖全球地震监测以了解地球深处过程的广泛兴趣，对全海洋深度仪器的科学需求日益得到承认。为詹姆斯·卡梅伦最近在马里亚纳海沟的挑战者深度进行的载人潜水而开发的全海洋深度技术，为私营部门提供了机会。此外，2013年1月还有一次机会巡航，该仪器将部署在大约8600米的地方，并收集大约一周的海底地震数据。广泛的影响：这一开发项目具有使用全海洋深度OBSS监测和预测大型破坏性海底地震风险区域的长期潜力。仅在过去十年中，大型海底地震就在全球夺走了数十万人的生命，造成了数千亿美元的损失，并导致了灾难性的环境破坏，如福岛核电站灾难。

This RAPID proposal seeks funding to develop, build and deploy a proto-type full ocean depth Ocean Bottom Seismograph (OBS) in the Mariana Trench in January 2013. Current OBSs are limited to deployment depths of 5000-6000m, and the few experiments that have deployed at or near those depths have had poorer instrument and data return rates. The scientific need for full ocean depth instruments is increasingly being recognized with recent large tsunamigenic subduction zone earthquakes, as well as broader interest in full global coverage of seismic monitoring for understanding deep earth processes.The PIs have been offered the opportunity to utilize full-ocean depth technology developed for the recent manned dive by James Cameron to Challenger Deep in the Mariana Trench. In addition, a cruise of opportunity exists in January 2013, in which the instrument will be deployed at about 8600 m and collect approximately a week of seismic data at depth.Broader Impacts:This development project has the long term potential for using full ocean depth OBSs to monitor and perhaps forecast areas at risk for large destructive submarine earthquakes. Large submarine earthquakes in the last decade alone have taken hundreds of thousands of lives globally, cost hundreds of billions of dollars and resulted in catastrophic environmental damage such as the Fukushima nuclear power plant disaster.
