Abstract	Western Boundary Currents Transport variations in the Florida Current by cross-stream voltages are continuing to be monitored using an abandoned cable between Key West, Florida, and Havana, Cuba, and an in-service cable between West Palm Beach, Florida, and Eight Mile Rock, Grand Bahama Island. The accuracy of the in-service voltages was upgraded by installing voltage recorders and a reference electrode at Eight Mile Rock to improve the accuracy of the voltage measurements being made at West Palm Beach. The voltage-derived transports from these cables are being used by Dynalysis of Princeton as a southern boundary condition for modeling the shelf circulation off the East Coast of the United States. This model is being used for pollution studies. The transport values are also being used to evaluate numerical models being developed for climate studies. Voltage measurements are also continuing for the Newfoundland cables that extend into the Labrador Sea. It is too early to evaluate transport variations in that region because only several months of data have been collected. Numerical models that can compute voltages for any cable using a numerically generated North Atlantic circulation are being developed under the auspices of the Community Modeling Effort and using a realistic geophysical model of the ocean topography, sea floor sediments, and continental and crustal material. PMEL has developed, for the first time, a self-consistent model of the electromagnetic fields generated by a realistic circulation model containing bottom topography. This modeling effort shows that long cables in the North Atlantic can be used to monitor the net north-south transport between the ends of the cable.
