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 while data from land seismographs can tell us much about large-scale structure and seismicity under the oceans, 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 (OBS). The construction, operation and maintenance of OBS requires specialized facilities and technical expertise that are beyond the ability of most individual investigators to maintain. The Ocean Bottom Seismometer Instrument Center (OBSIC) at the Woods Hole Oceanographic Institution (WHOI) will provide instrumentation and the skilled personnel to operate these instruments to all NSF-funded investigators whose research would benefit from seafloor seismic observations. WHOI has over 40 years of experience developing and operating ocean-bottom seismic instrumentation.The Ocean Bottom Seismometer Instrument Center (OBSIC) will provide state-of-the-art OBS instrumentation to the community while also evolving OBS operations toward an optimal, stable and strategic state. The state of the facility is optimal when data quality and the quantity of data that the facility can deliver are maximized for the available funding; it is stable when it is immune to perturbations (such as personnel changes or fluctuations in user demand), and it is strategic when new technologies and procedures are anticipated and seamlessly incorporated and standards of excellence are continuously rising. Key components of OBSIC include standardization of instrumentation, enhanced component tracking and the maintenance of instrumentation at a high readiness state, economical maximization of operational capacity through a combination of permanent OBSIC personnel and trained technicians from the UNOLS Marine Tech Pool and the USGS, and following a staffing and hiring plan that promotes continuous transfer of expertise, reducing risk to the health of the facility. Expansion of seismic capabilities to the marine environment has and will be necessary for national and international needs such as Earth hazards mitigation, environmental monitoring and marine resource exploitation. OBSIC will provide training in OBS science and instrumentation for a postdoctoral researcher, as well as for several engineering undergraduates. Outreach and information will be provided through an OBSIC website and through open meetings 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.

地震学是科学家用来研究地球结构和动态过程（例如地震和火山活动）的主要工具。 地球表面约 70% 被水覆盖，虽然陆地地震仪的数据可以告诉我们很多有关海底大尺度结构和地震活动的信息，但许多问题都与洋中脊、热点、俯冲带的性质有关，大陆边缘只能通过海底地震仪（OBS）获取的数据来解决。 OBS 的建设、运行和维护需要专门的设施和技术专长，这超出了大多数个体调查员的维护能力。 伍兹霍尔海洋研究所 (WHOI) 的海底地震仪仪器中心 (OBSIC) 将为所有 NSF 资助的研究人员提供仪器和操作这些仪器的技术人员，他们的研究将受益于海底地震观测。 WHOI 拥有 40 多年开发和运营海底地震仪器的经验。海底地震仪仪器中心 (OBSIC) 将为社区提供最先进的 OBS 仪器，同时也将 OBS 运营朝着优化、稳定和可靠的方向发展。战略状态。当设施可以提供的数据质量和数据量在可用资金下最大化时，设施的状态是最佳的；当它不受干扰（例如人员变动或用户需求波动）影响时，它是稳定的；当新技术和程序被预期并无缝整合以及卓越标准不断提高时，它是战略性的。 OBSIC 的关键组成部分包括仪器标准化、增强的组件跟踪和仪器处于高度准备状态的维护、通过永久 OBSIC 人员以及来自 UNOLS 海洋技术库和 USGS 的训练有素的技术人员的结合，以经济的方式最大化操作能力，以及以下人员配置和招聘计划，促进专业知识的持续转移，降低设施健康的风险。将地震能力扩展到海洋环境对于缓解地球灾害、环境监测和海洋资源开发等国家和国际需求来说是必要的。 OBSIC 将为一名博士后研究员以及几名工程本科生提供 OBS 科学和仪器方面的培训。外展和信息将通过 OBSIC 网站以及美国地球物理联盟年度秋季会议的公开会议提供。该奖项反映了 NSF 的法定使命，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。
