inlet of the Indian Ocean in Western Australia, between North West Cape and the mainland. It is 55 miles (90 km) long north to south and 30 miles across the mouth and has a maximum depth of 72 feet (22 m). Fishing, pearling, prawning, and tourism are the main local industries, and drilling for oil has taken place in the region. Nearby Cape Range National Park is important for the conservation of the rare yellow-footed rock wallaby. The west coast was charted by the Dutch navigator Abel Tasman in 1644. The gulf was named for Admiral Viscount Exmouth by Lieutenant Phillip Parker King, who surveyed the coast in 1818 in HMS Mermaid. The town of Exmouth was established in 1967 as a residential and service centre for a U.S. Naval communications station at North West Cape. Both the town and the station were severely damaged by a cyclone in 1999. All U.S. naval personnel left the station in 2002, and the facility subsequently became privately managed under the supervision of the Australian navy. Pop. (2001) urban centre, 3,031.
