RAPID: Oceanographic Instrumentation: R/V CAPE HATTERAS 2010 Rapid Response

该提案要求为哈特拉斯角R/V提供各种物品，以帮助实现OCE-0926699， PI Tracy Villareal博士的范围变更。最初的计划是研究墨西哥湾的重氮营养化群落，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测量和分析测量，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。本提案中所要求的仪器是满足范围变更所必需的。更广泛的影响：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使用工作、校准的仪器，降低研究成本，扩大潜在研究人员的基础。

This proposal requests a variety of items for R/V Cape Hatteras 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 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.
