This well-equipped 175-foot (53-meter) research vessel spends most of its time in the national marine sanctuaries off the West Coast, where it conducts oceanographic research, marine mammal population studies, and environmental assessments. Commissioned in 1966, the NOAA ship was named for U.S. Navy Lt. William P. McArthur, a pioneering 19th-century hydrographer.

During its three decades at sea the McArthur has undertaken a wide range of operations, including weather-balloon launches, acoustic surveys, and water-clarity observations. In addition to its three officers and 19 crew members, the ship can carry up to 13 scientists.

Shipboard researchers have access to two working laboratories and sophisticated data collection equipment, including an Acoustic Doppler Current Profiler that measures the current flowing below the vessel. Four cranes and three winches do the heavy lifting. The McArthur’s home port is the Pacific Marine Center on Lake Union in Seattle.
