Release: Approximately 400,000 gallons of Alaska North Slope crude oil.

The oil affected 60 square miles of ocean and washed ashore along roughly 14 miles of beaches, affecting seabirds and resulting in the closure of heavily used recreational beaches for up to 5 weeks. Approximately 3,400 birds died, and as many as 9,500 chicks were not born as a result of the spill. The brown pelican (Pelecanus occidentalis)—a federally listed endangered species—was severely affected. An estimated 195 of these birds died.
