The March 24 1989 oil spill by the Exxon Valdez in the Prince William
Sound (Alaska) released 260,000 barrels of oil and created a 6,700-km2
spill, of which 23% was removed. Total cleanup costs reached 1.2 billions,
around $400 per barrel spilled. Significant drops in fisheries (up to
40%) were observed in the following years.
