MRI RAPID: Deepwater Horizon Oil Spill: Acquisition of cavity ring-down spectroscopy systems to quantify concentration and stable isotopic composition of multiple carbon species.

PI要求核磁共振快速资金购买三个腔衰荡光谱(CRDS)系统，以量化海水样本中甲烷、溶解无机碳和溶解有机碳的同位素组成和浓度。这些仪器将被用来表征在深水地平线漏油附近采集的海水和沉积物样本中碳物种的浓度和同位素特征。这些仪器将提高追踪深水地平线漏油产生的石油和天然气的能力，因为这些石油和天然气经过处理并转化为溶解的无机碳、溶解的有机碳和微生物生物量。鉴于最近发生的墨西哥湾漏油事件，MRI快速投资是及时和关键的。更广泛的影响：这些工具将大大提高PI分析当前和未来通过当前墨西哥湾漏油快速资金收集的样本的能力。这项研究有可能促进我们对墨西哥湾生态系统中石油和天然气来源的碳流的理解，并有可能改进全球海洋碳循环模型。

The PI requests MRI RAPID funding to purchase three cavity ring-down spectroscopy (CRDS) systems to quantify the isotopic composition and concentration of methane, dissolved inorganic carbon, and dissolved organic carbon in seawater samples. These instruments will be used to characterize the concentration and isotopic signatures of carbon species in the seawater and sediment samples collected in the vicinity of the Deepwater Horizon Oil Spill. These instruments will improve the ability to trace oil and gas derived from the Deepwater Horizon Oil Spill as it is processed and transformed into dissolved inorganic carbon and dissolved organic carbon and microbial biomass. The MRI RAPID investment is timely and critical in light of the recent Gulf of Mexico oil spill. Broader Impacts: These instruments will substantially improve the PI's ability to analyze the current and future samples collected with current Gulf oil spill RAPID funding. This research has the potential to advance our understanding of oil and gas derived carbon flow in the Gulf of Mexico ecosystem and potentially improving global models of the oceanic carbon cycle.
