Renewal of the Ocean Bottom Seismic Instrument Center at Woods Hole Oceanographic Institution

该项目支持伍兹霍尔海洋研究所海底地震计仪器中心(OBSIC)的运作。该设施为NSF资助的研究人员提供仪器和人员，以获取世界各地的地震仪数据。地震学是科学家用来研究地球结构和动态过程的主要工具，如地震和火山活动。大约70%的地球表面被水覆盖，许多与大洋中脊、热点、俯冲带和大陆边缘的性质有关的问题只能通过海底地震仪获取的数据来解决。该奖项支持OBSIC在伍兹霍尔海洋研究所的继续运作，并建立在该设施最初5年的成就基础上。OBSIC将继续提供最先进的海底地震仪，以满足用户对各种仪器的需求，这些仪器能够在从长周期表面波到短周期气枪产生的体波的频谱上实现高保真记录。OBSIC数据度量中心将提供对数据质量的量化和易于理解的评估，以及地震仪定向、合规性和倾斜改正等数据产品，这将加快所有用户的数据分析。OBSIC的关键组成部分包括仪器的标准化、加强部件跟踪、将仪器维持在高度待命状态，以及维持来自其他机构的非OBSIC技术人员的增援能力，如联合国内罗毕办事处海洋技术库，以便在必要时增加海上OBSIC人员。该设施维护着一个网站，提供有关海底地震仪能力、OBS时间表和可用性的详细信息，正在进行的、未来的和已完成的实验的摘要，与地球望远镜数据管理中心使用OBSIC仪器获取的数据的链接，以及由OBSIC服务实现的论文书目。更多的外展和信息将通过公开会议提供，例如在美国地球物理联盟的年度秋季会议上。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This project supports the operation of the Ocean Bottom Seismometer Instrument Center (OBSIC) at the Woods Hole Oceanographic Institution. This facility provides instrumentation and personnel to acquire seismometer data throughout the world’s oceans to NSF-funded investigators. Seismology is the primary tool that scientists use to investigate Earth's structure and dynamic processes, such as earthquakes and volcanism. About 70% of Earth's surface is covered by water, and many questions related to the nature of mid-ocean ridges, hot-spots, subduction zones, and continental margins can only be addressed by data acquired with ocean-bottom seismometers. This award supports the continued operation of OBSIC at the Woods Hole Oceanographic Institution and builds upon the accomplishments of the facility’s initial 5 years. OBSIC will continue to provide state-of-the-art ocean-bottom seismometers that meet the needs of users for a mix of instruments that enable high-fidelity recording across the frequency spectrum extending from that of long-period surface waves to short-period airgun-generated body waves. The OBSIC Data Metrics Hub will provide quantitative and readily comprehended assessments of data quality, as well as data products such as seismometer orientations, compliance, and tilt corrections, that will speed up data analysis for all users. Key components of OBSIC include standardization of instrumentation, enhanced component tracking, the maintenance of instrumentation at a high readiness state, and sustaining a surge capacity of non-OBSIC technicians from other institutions such as the UNOLS Marine Tech Pool to augment OBSIC personnel at sea where necessary. The facility maintains a website that provides details on ocean-bottom seismometer capabilities, OBS scheduling and availability, summaries of on-going, future, and completed experiments, links to data acquired with OBSIC instrumentation at the Earthscope Data Management Center, and a bibliography of papers enabled by OBSIC services. Additional outreach and information will be provided through open meetings such as at the American Geophysical Union Annual Fall Meeting.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
