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.

该项目支持伍兹霍尔海洋研究所海底地震仪仪器中心 (OBSIC) 的运营，该设施为 NSF 资助的研究人员提供获取世界各地海洋地震仪数据的仪器和人员，地震学是科学家使用的主要工具。研究地球的结构和动态过程，例如地震和火山活动，大约 70% 的地球表面被水覆盖，以及许多与洋中脊性质相关的问题，热点、俯冲带和大陆边缘只能通过海底地震仪获取的数据来解决。该奖项支持伍兹霍尔海洋研究所 OBSIC 的持续运行，并以该设施最初 5 年的成就为基础。将继续提供最先进的海底地震仪，满足用户对多种仪器的需求，这些仪器能够在从OBSIC 数据指标中心将提供定量且易于理解的数据质量评估，以及地震仪方向、合规性和倾斜校正等数据产品，从而加快速度。 OBSIC 的关键组成部分包括仪器标准化、增强的组件跟踪、仪器处于​​高度准备状态的维护以及维持来自其他机构（例如美国国家实验室）的非 OBSIC 技术人员的激增能力。 UNOLS 海洋技术库可在必要时增强 OBSIC 人员的海上能力。该设施维护一个网站，提供有关海底地震仪功能、OBS 调度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以及通过该平台获取的数据的链接。 Earthscope 数据管理中心的 OBSIC 仪器以及 OBSIC 服务支持的论文书目将通过美国地球物理联盟秋季年会等公开会议提供。该奖项反映了 NSF 的贡献。法定使命，并通过使用基金会的智力优点和更广泛的影响审查标准进行评估，被认为值得支持。
