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.

PI要求资助开发一个自主的、可部署的深海地震系统，以便从远离海岸的地点提供长期和近实时的地震观测。基于两种成熟的技术，自主波动力水面船和海底地震仪，拟议的新一代仪器如果成功，将提供一种手段，不仅增加地震观测的全球覆盖范围，而且以负担得起的，实用的和可持续的方式增加各种海底观测。来自海洋地区台站的实时数据将大大提高地震参数的准确性，如位置和时刻。这些全球地震数据对于国家和国际机构监测和确定地震、海啸和核爆炸的特征至关重要。这对海啸预警系统来说尤其重要。这一新一代仪器将提供一种手段，不仅增加获取地震数据的机会，而且增加获取全球海洋上各种其他海底观测数据的机会。除了解决地球结构和构造的基本问题外，从海洋地区的台站提供实时数据将大大提高地震参数的准确性，如位置和时刻。这些全球地震数据对于国家和国际机构监测和确定地震、海啸和核爆炸的特征至关重要。这对海啸预警系统来说尤其重要。
