Accidental tanker oil spills (above 7 tonnes per spill), European seas

Despite the fact that the vast majority of spills are less than 7 tonnes, data on numbers and amounts are unreliable and such accidents are regarded to have a relatively small contribution to the overall quantity of oil spilled into the marine environment, as a result of tanker accidents.
Geographical coverage note: European Seas cover the north-east Atlantic, Baltic, Mediterranean and Black Sea
