On March 24, 1989 the oil tanker Exxon Valdez ran aground on Bligh Reef in Prince William Sound, Alaska, spilling an estimated 11 million gallons of crude oil across 1,300 miles of coastline - a catastrophic event that lead to one of the most thorough examinations of the effects of oil on the environment. While the vast majority of the spill area now appears to have recovered, pockets of crude oil remain in some locations, and there is evidence that some damage is continuing.

The Exxon Valdez Oil Spill (EVOS) Trustee Council was established with funds from the legal settlement between the State of Alaska, the Federal Government and Exxon to develop research, restoration and habitat conservation plans for the spill area. The NMFS Alaska Regional Administrator represents NOAA on the Council and oversees the NMFS Office of Exxon Valdez Oil Spill Damage Assessment and Restoration. The EVOS office administers projects carried out by NMFS researchers and outside contractors, and facilitates research planning and coordination between EVOS projects and other programs.
