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MRI RAPID资助购买三个空腔衰荡光谱（CRDS）系统，以量化海水样品中甲烷、溶解无机碳和溶解有机碳的同位素组成和浓度。这些仪器将用于表征深水地平线漏油事件附近收集的海水和沉积物样品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石油泄漏产生的石油和天然气的能力，因为石油和天然气被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。鉴于最近的墨西哥湾石油泄漏事件，MRI RAPID的投资是及时和关键的。更广泛的影响：这些仪器将大大提高PI分析当前和未来墨西哥湾漏油快速救援基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衍生碳流的理解，并有可能改进海洋碳循环的全球模型。

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.
