According to the international agreement MARPOL 73/78, any discharge of oil into the sea is prohibited. Illegal dumping is a major cause of degradation of marine and coastal life. Οil pollution at sea level is a phenomenon observed in the last three decades. Such pollution can be caused by accidental discharge (accidental damage from ships flushing tank, natural leakage) and accidental leaks from damaged ships or offshore installations. In the first case, we are usually dealing with small land contamination, which represents a large part of the total amount of oil entering the marine environment. Τhe second, is less common but usually implies higher volume release. In both cases, oil spills are a major threat to the environment and vulnerable marine ecosystems. Therefore, it is considered crucial to take action for rapid detection; effective emergency response is required for the detection, containment and recovery of oil spilled at sea. Οn this thesis we will study the satellite detection tools of oil spills. Dominant element is the automatic oil spill detection system using satellite remote sensing illustration Synthetic Aperture Radar SAR.
