RAPID: MRI - Acquisition of an Accelerated Solvent Extractor (ASE) to Rapidly Extract Petroleum Hydrocarbons from Atmospheric Samples in the Field During the 2010 Hurricane Season

PI要求MRI RAPID提供资金，以购买加速溶剂提取器（ASE），以便更快速有效地从与深水地平线石油泄漏相关的环境样本中提取碳氢化合物。这一建议补充了最近由NSF化学海洋学计划资助的海湾漏油RAPID，以量化2010年飓风季节通过深水地平线表面浮油的飓风通过大气沉积的碳氢化合物从海洋到陆地的转移。这将是有史以来第一次研究通过降雨将石油产品从海洋转移到陆地。自最初的RAPID提案提交以来，飓风亚历克斯引起的风暴潮扩大了许多墨西哥湾沿岸州的海岸暴露范围。这就需要在更广泛的地理采样网格中进行采样，将总样本数量从24个增加到144个，包括空气、雨水和湖水的采样！因此，更多的样本将需要采用更快的提取过程，以确保在整个2010年飓风季节及时分析。更广泛的影响从这项研究的结果可能会提供一个指标的生态系统健康受2010年飓风影响的高地地区是严重损害的深水地平线衍生碳氢化合物的湿和干沉积。这将是首次此类测量。

The PI requests MRI RAPID funding to acquire an Accelerated Solvent Extractor (ASE) to more rapidly and efficiently conduct hydrocarbon extractions from environmental samples related to the Deepwater Horizon oil spill. This proposal complements a Gulf oil spill RAPID recently funded by the NSF Chemical Oceanography program to quantify marine-to-land transfer of hydrocarbons via atmospheric deposition from hurricanes that pass through the Deepwater Horizon surface slick during the 2010 hurricane season. This will be the first study ever to address marine-to-land transfer of petroleum products via rainfall. Since submission of the original RAPID proposal storm surge from Hurricane Alex has expanded the coastal exposure of many of the Gulf Coast States. This necessitates sampling across a broader geographical sampling grid increasing the total sample count from 24 to 144 and includes sampling air, rainwater, and lake water! As a result a greater number of samples will necessitate adopting a faster extraction process to ensure timely analyses throughout the 2010 hurricane season.Broader Impacts The results from this study may provide an indication of ecosystem health in upland areas affected by 2010 hurricanes is severely compromised by wet and dry deposition of Deepwater Horizon-derived hydrocarbons. These will be the first such measurements.
