Every oil spill is different, but the thread that unites some major ones is a growing scientific awareness of the persistent damage that spills can do / N Y Times

"Only 20 years ago, the conventional wisdom was that oil spills did almost all their damage in the first weeks, as fresh oil loaded with toxic substances hit wildlife and marsh grasses, washed onto beaches and killed fish and turtles in the deep sea.

But disasters like the Valdez in 1989, the Ixtoc 1 in Mexico in 1979, the Amoco Cadiz in France in 1978 and two Cape Cod spills, including the Bouchard 65 barge in 1974 — all studied over decades with the improved techniques of modern chemistry and biology — have allowed scientists to paint a more complex portrait of what happens after a spill."

Supertankern Exxon Valdez's  grundstötning i Alaska.  Det är miljömässigt värre med oljeutsläpp i Alaska än i den Mexicanska bukten beroende på skillnaden i vattentemperatur kan man generellt säga, men problemet vad gäller efterverkningar lång tid efter oljeutsläppet är mer komplicerat. Något mer törs jag som icke-expert inte påstå.
