Cromwell Current
The Cromwell Current (also called Pacific Equatorial Undercurrent or just Equatorial Undercurrent) is an eastward-flowing subsurface current that extends the length of the equator in the Pacific Ocean.
The Cromwell Current was discovered in 1952〔Cromwell, Townsend (1953). "Circulation in a meridional plane in the central equatorial Pacific." ''Journal of Marine Research'' 12 196-213.〕〔Cromwell, T., Montgomery, R. B., and Stroup, E. D. (1954). ("Equatorial undercurrent in the Pacific Ocean revealed by new methods." ) ''Science'' 119 (3097) 648-649.〕 by Townsend Cromwell, a researcher with the Honolulu Laboratory. It is 250 miles (400 km) wide and flows to the east. It is hidden 300 feet (100 m) under the surface of the Pacific Ocean at the Equator and is relatively shallow compared to other ocean currents being only 100 feet from top to base. It has 1000 times the volume of Mississippi River and its length is 3500 miles (6000 km).
==Townsend Cromwell==
Townsend Cromwell, a keen surfer, swimmer and oceanographer, discovered the current that now bears his name whilst researching drifting in the equatorial region of the Pacific Ocean. He died in 1958 when his plane crashed en route to an oceanography expedition.
