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

本提案要求为R/V Oceanus提供各种项目，以帮助完成OCE-0926699范围变更，Tracy Villareal博士，PI。最初的计划是研究墨西哥湾的重氮营养群落，但石油泄漏严重影响了这些群落。研究的范围现在将集中在泄漏对南极洲社区的影响。这些研究将包括碳氢化合物的荧光和分析测量、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和颗粒部分的同位素特征。本建议书中要求的仪器是完成范围变更所必需的。更广泛的影响：本提案的主要影响是在标准二下，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任何美国大学或实验室的NSF资助的研究人员使用工作、校准仪器进行研究，降低研究成本，并扩大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.
