Oil spills

Oil-spill monitoring detects surface oil, maps slick extent, screens look-alike features, and cues incident response or enforcement from SAR backscatter, optical context, and maritime evidence.^[1][2][3] Synthetic Aperture Radar is the main satellite sensor for oil spill detection because it can observe slick-related sea-surface roughness changes.^[1] Sentinel-1 imagery can detect oil-spill signatures and supports marine slick mapping.^[2] Satellite SAR is an operational tool for oil-spill monitoring and assessment, while multi-sensor data can support thickness classification.^[3]
