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

国际和平研究所要求提供资金，以开发一个自主的、可部署的深海地震系统，以便从遥远的近海地点提供长期和近实时的地震观测。拟议中的新一代仪器建立在两项经过验证的技术--自主波浪动力水面船和海底地震仪--的基础上，如果成功，将提供一种手段，不仅可以扩大地震观测的全球覆盖范围，而且可以以负担得起、实用和可持续的方式扩大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显著提高位置和力矩等地震参数的精度。这种全球地震学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都至关重要。这对海啸预警系统尤其重要。这一新一代仪器将不仅提供获取地震数据的途径，而且还提供获取全球海洋上各种其他海底观测资料的途径。广泛影响：这一新能力将使考虑在海洋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，提供海洋地区地震台站的实时数据还将显著提高地震参数(如位置和力矩)的准确性。这种全球地震学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都至关重要。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.
