Previous studies have suggested that tropical storms may introduce marine organic matter onto land via precipitation. In the context of the Deepwater Horizon oil spill that occurred in the northern Gulf of Mexico in April, 2010, it is natural to focus attention on the potential for storms in this region to transport and deposit some portion of the pollutant oil inland. As of June 10, 2010, a conservative estimate of the surface slick in the Gulf is 45,000 square kilometers. While attention is currently focused overwhelmingly on impacts in the open marine and coastal environments, little -- if any -- attention has been given to examining the potential for tropical storms and hurricanes to move oil spill contaminants far inland.With funding through this Grant for Rapid Response Research (RAPID) researchers at East Carolina University will take a first look at the conveyance of components of the Deepwater Horizon to short-range and longer-range inland sites via the sea storm - rainfall route. Post-storm rainfall samples will be collected at one coastal site (Lake Pontchartrain) and at one or more inland sites for analysis for aliphatic hydrocarbon (finger-printed to the material from the oil spill) and carbon isotopic composition. This will be the first study of its kind.Broader Impacts: Besides the obvious relevance to advancing our understanding of the near- and far-field environmental and human health impacts of the Deepwater Horizon spill, this simple study will also inform scientists, environmental managers, and policy makers working dealing with similar environmental catastrophes in the future and at other places. A first-year female graduate student will also participate in this project.

以前的研究表明，热带风暴可能会通过降水将海洋有机物带到陆地上。 在2010年4月墨西哥湾北方发生的深水地平线石油泄漏事件的背景下，自然会将注意力集中在该地区风暴将部分污染物石油输送和存款到内陆的可能性上。 截至2010年6月10日，保守估计墨西哥湾的表面浮油面积为45，000平方公里。 虽然目前的注意力主要集中在开阔海洋和沿海环境的影响上，很少有人关注热带风暴和飓风将石油泄漏污染物转移到内陆的可能性。东卡罗莱纳大学的研究人员将首先研究深水地平线的组成部分通过海上风暴向短程和远程内陆地点的运输-降雨路线 将在一个沿海地点（庞恰特雷恩湖）和一个或多个内陆地点收集风暴后降雨样本，用于分析脂肪烃（对漏油物质进行指纹分析）和碳同位素组成。 更广泛的影响：这项简单的研究除了有助于我们进一步了解深水地平线泄漏对近场和远场环境和人类健康的影响外，还将为科学家、环境管理者和政策制定者提供信息，帮助他们在未来和其他地方处理类似的环境灾难。 一名一年级女研究生也将参加该项目。
