Upgrading UNOLS Academic Research Fleet (ARF) Marine Gravimeters Oceanographic Instrumentation Program Proposal 2022

伍兹霍尔海洋研究所(WHOI)的势场池设备(PFPE)设施由其船上科学服务组(SSSG)运营，该设施认识到，提出和执行BGM3生命周期替换计划对美国海洋研究中海洋重力能力的未来至关重要。这项提案要求购买在学术研究船队(ARF)船上操作海洋重力仪的两个关键物品。PI讨论了为联合国全球海洋观测系统全球级船只提供一台动态重力系统海洋重力仪和为研究船N.B.Palmer号提供一台动态重力系统海洋重力仪的理由。1)ARF全球级船舶的DGS重力仪$382,500 2)R/V的DGS重力仪$382,500$765,000更广泛的影响本提案的主要影响是根据提案指南(NSF 19-602)的优点审查标准2。它为科学家提供基础设施支持，以使用该船及其共享仪器，以支持他们由NSF资助的海洋研究项目(这些项目单独接受NSF相关研究计划的单独审查)。共享仪器的获取、维护和操作允许美国国家科学基金会资助的任何美国大学或实验室的研究人员获得用于其研究的工作、校准的仪器，从而降低研究成本，并扩大潜在研究人员的基础。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。

The Woods Hole Oceanographic Institution’s (WHOI) Potential Fields Pool Equipment (PFPE) Facility, operated under its Shipboard Scientific Services Group (SSSG) recognizes that proposing and executing a BGM3 life cycle replacement plan is central to the future of marine gravity capability in US oceanographic research. This proposal requests the purchase of two critical items for operating marine gravimeters onboard academic research fleet (ARF) vessels. The PI discusses the rationale to fund one Dynamic Gravity Systems (DGS) marine gravimeter for a UNOLS Global Class vessel, and one DGS marine gravimeter for the research vessel N.B. Palmer. 1) DGS gravimeter for a ARF Global Class vessel $382,500 2) DGS gravimeter for R/V N. B. Palmer $382,500 $765,000 Broader ImpactsThe principal impact of the present proposal is under Merit Review Criterion 2 of the Proposal Guidelines (NSF 19-602). It provides infrastructure support for scientists to use the vessel and its shared-use instrumentation in support of their NSF-funded oceanographic research projects (which individually undergo separate review by the relevant research program of NSF). The acquisition, maintenance and operation of shared-use instrumentation allows NSF-funded researchers from any US university or lab access to working, calibrated instruments for their research, reducing the cost of that research, and expanding the base of potential researchers.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.
