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的主要工具，例如地震和火山主义。 大约70％的地球表面被水覆盖，尽管土地地震仪的数据可以告诉我们有关海洋下的大规模结构和地震性的信息，但许多与中海山脊，热点，俯冲区和大陆边缘的性质有关的问题只能通过bottom seismistom的数据来解决。 OBS的构建，运营和维护需要专门的设施和技术专长，这些设施和技术专长超出了大多数个人调查人员的维护能力。 伍兹孔海洋学机构（WHOI）的海洋底部地震计仪器中心（观察）将为所有NSF资助的研究人员提供仪器和熟练的人员，他们的研究将受益于海底地震观察。 Whoi拥有40多年的开发和运营海底地震仪器的经验。海洋底部地震仪仪器中心（观察）将为社区提供最新的观察仪器，同时也将观察行动发展为最佳，稳定和战略状态。当数据质量和设施可以提供的数据数量最大化以获得可用资金时，该设施的状态是最佳的；当它免疫扰动时（例如人员变化或用户需求的波动），它是稳定的，当预期新技术和程序时，它是战略性的，并且无缝地融合了并且卓越标准持续上升。 观察的关键组成部分包括仪器的标准化，增强的组件跟踪以及在高昂的准备状态下维护仪器，通过结合永久性观察人员和UNOL海洋技术池和USG的培训技术人员的经济最大化运营能力，以及在促进持续转移的机构转移的人数和雇用计划之后。扩大对海洋环境的地震能力的扩展对于国家和国际需求（例如缓解地球危害，环境监测和海洋资源开发）是必不可少的。观察将为博士后研究人员以及几位工程本科生提供OBS科学和仪器的培训。宣传和信息将通过观察网站以及在美国地球物理联盟年度秋季会议上的公开会议提供。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的审查标准通过评估来获得支持的。
