Evolution of oil slick patterns as observed by SAR off the coast of Wales

摘要: Imagery from three different Synthetic Aperture Radar (SAR) spaceborne sensors were obtained over the coast of Wales, UK. These observations indicated persistence slick features associated with grounding on February 15, 1996 Sea Empress anker at entrance Milford Haven estuary and resulting rnassive oil spill that followed. RADARSAT, ERS-1, ERS-2 SAR images revealed evolution these 22 to 26, 1996. The feature tracking Maximum Similarity Shape Matching method (MSSM) developed University Delaware College Marine Studies (CMS) was applied pair ERS images. MSSM calculated drift speeds about 10 cm/s. Observations pattern in imagery compared available reports ground conditions. Deformation also evident data throughout five-day period.
