Western Boundary Currents


This work is no longer being carried out at PMEL. Please see the pages titled Florida Current Transport from Voltage Measurements at the Atlantic Oceanographic and Meteorological Laboratory. These pages describe ongoing measurements of the Florida Current via submarine cables.


Transport variations in the Florida Current are being continually monitored by measuring the cross-stream voltages using an in-service cable between West Palm Beach, Florida, and Eight Mile Rock, Grand Bahama Island, and an abandoned cable between Key West, Florida, and Havana, Cuba. Fifteen years of these voltage-derived transport measurements from the cables have been collected. The data are being used in models of the circulation off the East Coast of the United States, and to evaluate numerical models being developed for climate studies. Voltage measurements are being made in several other locations by a number of different researchers in the Pacific and Atlantic oceans, and are in the planning stages for other cables.
