Funds are awarded to carry out a baseline assessment of the impacts on the ecology of the Gulf Coast marshes resulting from BP Deepwater Horizon Oil Spill. The associated coastal wetlands, estuaries and lagoon systems of the Gulf Coast are an irreplaceable national resource and comprise a unique suite of ecosystems of rich biodiversity and widely recognized ecological and economic value. Because of the toxicity of all weights of crude oil there is the potential for smothering, significant injury and mortality of the tidal wetlands. This RAPID project will address a number of critical scientific questions about the impact of this environmental disaster on the ecosystems of the Gulf including: quantifying the extent of the spill, ecological consequences, and environmental factors that contributed. The project will focus on the application of innovative and unique algorithms and computer programs to convert hyperspectral data from the Advanced Visible Infrared Imaging Spectrometer into measurements of coast marsh vegetation functional types and species; map species/functional type; estimate density of vegetation; evaluate evidence of vegetation stress by comparing contaminated vs. uncontaminated vegetation; and map the location of oil contamination in the wetlands. The research will be valuable to state and federal resource managers, policy makers, and citizens of the region. The data will establish a baseline to measure the longer term consequences to the oil spill.

获得资金用于对英国石油公司深水地平线漏油事件对墨西哥湾沿岸沼泽生态的影响进行基线评估。墨西哥湾沿岸相关的沿海湿地、河口和泻湖系统是不可替代的国家资源，包括一套独特的生态系统，具有丰富的生物多样性和广泛公认的生态和经济价值。由于所有重量的原油的毒性，有可能窒息，严重伤害和死亡的潮汐湿地。这个快速项目将解决一些关键的科学问题，这场环境灾难对海湾生态系统的影响，包括：量化泄漏的程度，生态后果和环境因素的贡献。 该项目将侧重于应用创新和独特的算法和计算机程序，将高级可见红外成像光谱仪的高光谱数据转换为海岸沼泽植被功能类型和物种的测量数据;绘制物种/功能类型图;估计植被密度;通过比较受污染植被与未受污染植被来评估植被压力的证据;绘制湿地中石油污染的位置图。这项研究对州和联邦资源管理者、政策制定者和该地区的公民都很有价值。这些数据将建立一个基准，以衡量石油泄漏的长期后果。
