This proposal requests support for development of improved ocean bottom seismometers at Scripps Institution of Oceanography. The proposed effort will increase the number of instruments available for shared-use research utilization by US academic researchers by 70, including ten new broadband instruments for long, normally passive deployments of a year or more, and sixty new instruments for active source projects, which normally require shorter deployments of a month or less. The proposal will also retrofit existing instruments with new seismometers and new dataloggers, and provide other upgrades to increase capabilities at the two instrument centers.Broader Impacts The OBSIP facilities provide an important shared-use capability for marine seismic researchers, enabling researchers without institutional seismometer resources to undertake cutting-edge research in marine seismology and geophysics. The upgrade and expansion of capabilities supported here will improve that capability, offering researchers and their students access to the tools needed to record earthquake signatures, to obtain structural data from active source experiments, and to undertake tomographic studies to expand our understanding of the earth's structure at a wide range of scales.

该提案要求支持斯克里普斯海洋学研究所开发改进的海底地震仪。 这项计划将使美国学术研究人员可用于共享研究的仪器数量增加70台，其中包括10台用于长期、通常被动部署一年或更长时间的新宽带仪器，以及60台用于主动源项目的新仪器，这些项目通常需要更短的部署时间，即一个月或更短。该计划还将用新的地震仪和新的数据记录器改造现有仪器，OBSIP设施为海洋地震研究人员提供了重要的共享使用能力，使没有机构地震仪资源的研究人员能够进行海洋地震学和海洋物理学的前沿研究。 这里支持的能力的升级和扩展将提高这种能力，为研究人员及其学生提供记录地震特征所需的工具，从活动源实验中获得结构数据，并进行层析成像研究，以扩大我们对地球结构的理解。
