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.

PI要求MRI快速资金购买三个空腔戒指光谱（CRDS）系统，以量化甲烷的同位素组成和浓度，溶解的无机碳和在海水样品中溶解的有机碳。这些仪器将用于表征海水中碳物种的浓度和同位素特征，以及在深水地平线溢油附近收集的沉积物样品。这些仪器将在处理并转化为溶解的无机碳和溶解的有机碳和微生物生物量时，提高从深水地平线漏油中衍生的石油和气体的能力。鉴于最近墨西哥石油漏油事件，MRI快速投资是及时且至关重要的。 更广泛的影响：这些仪器将大大提高PI分析当前海湾石油漏油快速资金收集的当前和未来样品的能力。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的碳流量的理解，并有可能改善海洋碳循环的全球模型。
