项目摘要

This is a RAPID award to respond to the Deep Horizon oil spill in the Gulf of Mexico. The work involves the time series collection of samples to examine the changes, from baseline conditions to maximum exposure, to the oil leaking out of the deepwater well head to a variety of coastal sites along the Northern Gulf of Mexico. Sampling sites include the intertidal zone at Belle Fontaine Point in eastern Mississippi and the New Harbor Islands in Louisiana. Samples and analytical work will determine hydrocarbon transformations and changes due to biogeochemical processes, changes in bioturbation rates, and changes in the assemblages of benthic macro- and meiofauna over time. Implications of these variables for physical and sedimentary processes and for macrofauna will be assessed. Broader impacts of the work will have immediate implications for understanding the impacts of the oil spill on coastal ecosystems and provide data to examine the time scale of ecosystem crash and recovery. The work will have potential for mitigating the long term effects of the oil spill on coastal systems. The work will also train students and provide public outreach activities that will be carried out in collaboration with the Northern Gulf Institution and with NOAA.

这是针对墨西哥湾“深地平线”石油泄漏事件的快速响应奖。这项工作包括收集样本的时间序列，以检查从基线条件到最大暴露量的变化，以及石油从深水井口泄漏到墨西哥湾北部各种沿海地点的变化。采样地点包括密西西比州东部贝尔方丹角的潮间带和路易斯安那州的新港群岛。样品和分析工作将确定由于生物地球化学过程、生物扰动率的变化以及底栖大型和小型动物组合随时间的变化而引起的碳氢化合物转化和变化。将评估这些变量对物理和沉积过程以及大型动物群的影响。这项工作的广泛影响将对了解石油泄漏对沿海生态系统的影响产生直接影响，并为检查生态系统崩溃和恢复的时间尺度提供数据。这项工作将有可能减轻石油泄漏对沿海系统的长期影响。这项工作还将培训学生，并提供公共宣传活动，这些活动将与北湾研究所和NOAA合作开展。
