Oil Slicks
 Every year oceans, seas and coasts are polluted by mineral oil mainly due to:
- tanker rupture, due to accident, malfunction or difficult weather conditions
- illegal oil discharges by ships during "normal operations"
- natural oil seepage
The resulting oil slicks are difficult to control, as their evolution depends on weather, currents, tides, and many chemical and physical factors (like the presence of icebergs). It is important to get an overall view of the phenomenon to determine its extent and, if possible, to predict the way it will move.
 The Synthetic Aperture Radar (SAR) instrument, which can collect data independently of weather and light conditions, is an excellent tool to monitor and detect oil on water surfaces. This instrument offers the most effective means of monitoring oil pollution: oil slicks appear as dark patches on SAR images because of the damping effect of the oil on the backscattered signals from the radar instrument.
