Oil spill statistical assessment at MC-20 Taylor oil spill site from satellite imagery in 2004-2016

This dataset includes oil presence/absence data and delineated oil slick polygons (in the study include Landsat TM, Landsat ETM+, Landsat OLI and Sentinel-2A.shapefiles) from satellite imagery at the MC-20 Taylor oil spill site in 2004-2016. Oil slicks were identified from its spatial contrast with clear water and its unique spectral response comparing to oil look-alikes (like Sargassum or Trichodesmium mats). Identified oil slicks without large cloud blockage are then delineated manually in ArcMAP.

本数据集涵盖2004至2016年MC-20泰勒溢油站点（MC-20 Taylor oil spill site）的卫星影像油膜存在/缺失标注数据，以及以形状文件（shapefile）格式存储的人工划定油膜多边形数据，相关研究采用的卫星影像传感器包括Landsat TM、Landsat ETM+、Landsat OLI及Sentinel-2A。油膜的识别依据其与清洁水体的空间对比度，以及相较于油膜假象物（如马尾藻（Sargassum）藻垫或束毛藻（Trichodesmium）藻垫）的独特光谱响应特征。针对未受大面积云遮挡的已识别油膜，研究人员随后在ArcMAP中完成了油膜边界的人工划定。
