Prince William Sound

Prince William Sound is a sound of the Gulf of Alaska on the south coast of the U.S. state of Alaska. It is located on the east side of the Kenai Peninsula. Its largest port is Valdez, at the southern terminus of the Trans-Alaska Pipeline System.

In 1989, the oil tanker Exxon Valdez ran aground on Bligh Reef after leaving Valdez, causing a large oil spill, which resulted in massive damage to the environment, including the killing of around 250,000 seabirds, nearly 3,000 sea otters, 300 harbour seals, 250 bald eagles and up to 22 killer whales.[
