德克萨斯农工大学（TAMU）的地球化学环境研究小组（GERG）需要ROV兼容仪器框架的仪器和材料。这些仪器建议作为舰队共用仪器。他们的国家科学基金会资助项目OCE #1851378 （TAMU）和1851365 （FSU）的第一次研究巡航，题为“合作研究：抵制溶解：解开北太平洋深海硬核珊瑚礁在不饱和水域的谜团”，原定于2020年9月进行，但由于供应商因COVID-19关闭而延迟交付深海珊瑚着陆器的关键仪器，因此推迟了（目前计划于2021年8月）。此外，联卢观察团安全审查小组注意到它们的仪器缺乏冗余，为了解决这一问题，建议提出关于部署第二套仪器的海洋仪器建议。仪器着陆器由SAMI-pH、SAMI-CO2和Aanderaa声学多普勒电流分析器（ADCP）组成，带有CTD、氧气传感器和数据记录器。拟议的海洋仪器包括：1)SAMI-pH $24,0362) SAMI-CO2 $28,7963) Aanderaa ADCP $36,7264) ROV兼容框架$9,969 $99,527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使用的仪器来支持他们的国家科学基金会资助的海洋学研究项目（这些项目单独接受国家科学基金会相关研究计划的单独审查）。共享使用仪器的获取、维护和操作允许来自任何美国大学或实验室的nsf资助的研究人员为他们的研究访问工作、校准仪器，降低研究成本，并扩大潜在研究人员的基础。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识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 Geochemical Environmental Research Group (GERG) at Texas A&M University (TAMU) requests instrumentation as well as materials for ROV compatible instrument frames. These instruments are proposed as shared-use instruments for the fleet. The first research cruise for their NSF funded project, OCE #1851378 (TAMU) and 1851365 (FSU), titled “Collaborative Research: Defying Dissolution: Unraveling the Enigma of North Pacific Deep-Sea Scleractinian Reefs in Undersaturated Water” was originally scheduled for September 2020 and was postponed (currently scheduled for August 2021) because delivery of critical instrumentation for the deep-sea coral lander was delayed due to COVID-19 closures by suppliers. In addition, the lack of redundancy in their instruments was noted by the UNOLS safety review panel and to remedy this concern were advised to submit this Oceanographic Instrumentation proposal for a second set of instruments to deploy. The instrument lander consists of a SAMI-pH, SAMI-CO2, and Aanderaa Acoustic Doppler Current Profiler (ADCP) with CTD, oxygen sensor, and data logger. The proposed Oceanographic Instrumentation includes:1) SAMI-pH $24,0362) SAMI-CO2 $28,7963) Aanderaa ADCP $36,7264) ROV compatible frame $9,969 $99,527Broader Impacts The 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.
