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.

伍德霍尔海洋研究所 (WHOI) 运营的势场池设备 (PFP​​E) 为美国海洋学界，特别是学术研究舰队 (ARF) 提供海洋重力仪专业知识、仪器和支持。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，并将这种新的重力采集系统集成到目前使用的 BGM-3 海洋重力仪中。 PFPE 由美国国家科学基金会 (NSF) 资助，几十年来一直致力于支持研究船上的学术势场测量。 ARF 目前使用的 BGM-3 重力仪系统已有 30-40 年的历史。虽然这些重力计可产生出色的数据，但它们包含机电传感器，在处理/运输时需要大量维护和保养，并且属于 ITAR（国际武器贸易条例）分类。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着优势，并且不受 ITAR 控制。这里建议使用一米：DgS AT 重力计 $348,146 更广泛的影响 当前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。它为科学家使用该船及其共享仪器提供基础设施支持，以支持其 NSF 资助的海洋学研究项目（这些项目单独接受 NSF 相关研究计划的单独审查）。 共享仪器的采购、维护和操作使美国任何大学或实验室的 NSF 资助的研究人员都可以使用经过校准的工作仪器进行研究，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，NSF 的法定使命被认为值得支持。
