RAPID: Oceanographic Instrumentation: R/V OCEANUS 2010 RAPID Response

这份提案要求为R/V Ocean提供各种物品，以帮助满足OCE-0926699的范围更改，特雷西·维拉雷亚尔博士，PI。最初的计划是研究墨西哥湾的重氮营养群落，但漏油事件严重影响了这些群落。研究的范围现在将集中在漏油对浮游生物群落的影响上。这些研究将包括碳氢化合物的荧光和分析措施，微生物和后生动物群落的功能和分类变化，以及泄漏的溶解部分和颗粒部分的同位素特征。为了满足范围的变化，本提案中要求的工具是必要的。更广泛的影响：本提案的主要影响是在标准2下，为科学家使用该船及其共享使用的仪器提供基础设施支持，以支持他们由NSF资助的海洋研究项目(这些项目分别由NSF的相关研究计划单独审查)。共享仪器的获取、维护和操作使任何美国大学或实验室的NSF资助的研究人员都可以获得用于其研究的工作、校准的仪器，从而降低了研究成本，并扩大了潜在研究人员的基础。

This proposal requests a variety of items for R/V Oceanus to help fulfill the change of scope for OCE-0926699, Dr. Tracy Villareal, PI. The original plan was to study he diazotrophic communities in the Gulf of Mexico, but the oil spill has seriously affected these communities. The scope of the study will now concentrate on the impact of the spill on the planktonic communities. The studies will include fluorimetric and analytic measures of hydrocarbons, functional and taxonomic changes in microbial and metazoan communities, and isotopic signatures of both the dissolved and particulate fractions of the spill. The instrumentation requested in this proposal is necessary to fulfill the change in scope. Broader Impacts: The principal impact of the present proposal is under criterion two, providing 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.
