Townsend Cromwell

Who was Townsend Cromwell?

Townsend Cromwell was an oceanographer who discovered the Cromwell current whilst researching drifting in the equatorial region of the Pacific Ocean. He died in 1958 when his plane crashed while he was en route to an oceanography expedition.

The prominent oceanographer of the equatorial Pacific, Townsend Cromwell, was killed in an airplane crash on 2 June 1958. The accident, also fatal to B. Shimada, occurred near Guadalajara as these men were en route to join the Scot Expedition at Acapulco. Cromwell was Senior Scientist with the Inter-American Tropical Tuna Commission and Research Associate at Scripps Institution of Oceanography, La Jolla, California. His field of work was the physical environment and its relation to fisheries. He became a weather officer in the Army Air Force during World War II.. After receiving a B.A. degree from University of California in 1947, he returned to La Jolla, his boyhood home, as a student at Scripps, receiving an M.S. degree in oceanography from the University of California in 1949. At Scripps he was strongly influenced by H. U. Sverdrup.

From 1949 to 1953 he was Oceanographer at Pacific Oceanic Fishery Investigations, Honolulu, O. E. Sette, then Director, and Cromwell initiated a far-sighted and intensive survey of the physical and biological characteristics of Pacific equatorial waters, which had been the subject of much speculation but little observation. For many months he participated in the field work from the HUGH M. SMITH, and for more and harder months he carried out the analysis of the observations. As a result of this pioneering work, the knowledge of the physical and biological structure of the equatorial Pacific Ocean has been vastly advanced. These achievements are the more remarkable when one notes that comparable surveys of the equatorial Atlantic and Indian oceans are still lacking.
