Woods Hole Oceanographic Institution/UNOLS Fleet: The future of marine gravimetry for geophysical research by the UNOLS academic research vessel fleet

由伍德霍尔海洋研究所(WHOI)运营的潜在野外池设备(PFPE)向美国海洋学界，特别是学术研究船队提供海洋重力仪专业知识、仪器和支助。他们提议购买一台新的DGS高分辨率先进技术(AT)海洋重力仪，并将这一新的重力采集系统整合到目前使用的BGM-3海洋重力仪机队中。PFPE由美国国家科学基金会(NSF)资助，几十年来一直在支持考察船上的学术势场测量。目前在ARF中使用的BGM-3重力仪系统已有30-40年的历史。虽然这些重力仪产生了出色的数据，但它们包含的机电传感器在搬运/运输过程中需要广泛的维护和护理，而且它们被归类为ITAR(国际武器贩运法规)。随着时间的推移，新一代重力仪将在操作和维护方面提供显著优势，并且不受ITAR控制。这里建议一米：DGS AT重力仪$348,146更广泛的影响本建议的主要影响是根据建议指南(NSF 19-602)的功绩审查标准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 Potential Field Pool Equipment (PFPE) operated out of Wood Hole Oceanographic Institution (WHOI) provides marine gravimeter expertise, instrumentation and support to the United States oceanographic community, specifically the Academic Research Fleet (ARF). They propose to acquire a new DgS high-resolution advance technology (AT) marine gravimeter and integrate this new gravity acquisition system into the fleet of BGM-3 marine gravimeters currently in use. PFPE is funded by the US National Science Foundation (NSF) and has been operating for several decades in support of academic potential fields measurements on research ships. Current BGM-3 gravimeter systems used in the ARF are between 30-40 years old. While these gravimeters produce excellent data, they contain electromechanical sensors that require extensive maintenance and care in handling/shipping, and they are ITAR (International Traffic in Arms Regulations) classified. New-generation gravimeters will provide significant advantage in operations and maintenance over time and are not subject to ITAR controls. One meter is proposed here:DgS AT gravimeter $348,146 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.
