Oil spill monitoring

SAR image with coloured lines marking the location of oil slicks observed in a time series of SAR images. These mark the locations of thin oil slicks leaking from the fuel tanks of the Volgoneft, which broke up and sank the previous November. As the oil from the tank resurfaced, the oil spread in a downwind direction. Because the wind direction varied over the 2 month period, the lines marking the oil location in each image form a star centered on the location of the wreck.
