Texas A&M proposes to acquire a 5-channel nutrient autoanalyzer for use at sea for the measurement of nitrate, nitrite, phosphate, silicate and ammonia during research cruises carried out by personnel from the Department of Oceanography at Texas A&M University and the Departments of Marine Biology and Marine Science at Texas A&M University, Galveston. Such measurements are currently made using samples collected at sea and frozen, then analyzed on an old Astoria-Pacific instrument at the laboratory at the Geochemical and Environmental Research Group (GERG). Having an instrument that can go to sea would mean more timely and accurate results for their programs. Texas A&M Provided technical descriptions and rationale for the acquisition of the following Oceanographic Instrumentation: 1) SEAL AA500 autoanalyzer $100,590 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.

德克萨斯农工大学提议购置一台5通道营养素自动分析仪，用于在德克萨斯农工大学海洋学系和位于加尔维斯顿的德克萨斯农工大学海洋生物学系和海洋科学系的人员进行研究航行期间在海上测量硝酸盐、亚硝酸盐、磷酸盐、硅酸盐和氨。目前，这种测量是使用在海上收集并冷冻的样本进行的，然后在地球化学和环境研究小组（GERG）实验室的旧阿斯托里亚-太平洋仪器上进行分析。拥有一台可以出海的仪器将意味着他们的项目将得到更及时、更准确的结果。德克萨斯A M公司提供了购买下列海洋仪器的技术说明和理由：1）SEAL AA 500自动分析仪100，590美元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Merit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）。 共享使用仪器的获取、维护和操作允许来自美国任何大学或实验室的NSF资助的研究人员使用工作、校准的仪器进行研究，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。
