MRI: Development of an Autonomously Deployed Deep-Ocean Seismic System

PI申请资金用于开发一个自主的、可部署的深海地震系统，从遥远的海上站点提供长期和近实时的地震观测。基于两项成熟的技术，自主波浪动力水面船和海底地震仪，如果成功，新一代仪器将提供一种手段，不仅可以增加地震观测的全球覆盖范围，还可以以一种经济、实用和可持续的方式增加各种海底观测的覆盖范围。来自海洋地区台站的实时数据将大大提高地震位置和矩等参数的准确性。这样的全球地震数据对于国家和国际机构监测和描述地震、海啸和核爆炸是至关重要的。这对海啸预警系统尤其重要。这种新一代仪器将提供一种手段，不仅可以增加对地震数据的访问，还可以增加对全球海洋上各种其他海底观测数据的访问。更广泛的影响：这种新的能力将使考虑在海洋的任何偏远地区部署海底观测站成为现实。除了解决地球结构和构造的基本问题外，提供海洋地区台站的实时数据将大大提高地震参数（如位置和力矩）的准确性。这样的全球地震数据对于国家和国际机构监测和描述地震、海啸和核爆炸是至关重要的。这对海啸预警系统尤其重要。

The PI's request funding to develop an autonomously, deployable, deep-ocean seismic system to provide long-term and near-real-time seismographic observations from sites far offshore. Building upon two proven technologies, autonomous wave-powered surface boats and ocean bottom seismometers, the proposed new generation instrument will, if successful, provide a means of increasing global coverage not only of seismic observations, but also of a variety of ocean bottom observables in an affordable, practical, and sustainable way. Real-time data from stations in oceanic areas will significantly increase the accuracy of earthquake parameters such as location and moment. Such global seismographic data are critical for both national and international agencies in monitoring and characterizing earthquakes, tsunamis, and nuclear explosions. This is particularly critical for tsunami warning systems. This new generation instrument will provide a means of increasing access to not only seismic data, but also to a variety of other ocean bottom observables over the global oceans.Broader Impacts: This new capability would make it realistic to consider the deployment of seafloor observatories in any remote areas of the oceans. In addition to addressing fundamental questions of Earth structure and tectonics, providing real-time data from stations in oceanic areas will significantly increase the accuracy of earthquake parameters such as location and moment. Such global seismographic data are critical for both national and international agencies in monitoring and characterizing earthquakes, tsunamis, and nuclear explosions. This is particularly critical for tsunami warning systems.
