The purpose of this work was to understand electrical fluctuations forced by turbulent velocity fluctuations in the bottom boundary layer of the coastal ocean. For this purpose, the Woods Hole Oceanographic Institution WHOI deployed two tripods containing novel acoustic vorticity sensors in the Strait of Juan de Fuca, in Washington state, for a period of approximately eight months. In a companion project funded under a separate grant, the Scripps Institution of Oceanography, deployed a sensor designed to measure electrical fluctuations at the same site during the same period. The vorticity measurements were successful, but the electrical instrumentation developed problems and did not produce usable data. In a follow up study, essentially the same set of instrumentation was deployed for a one month period on the continental shelf off Eureka, California. The flow measurements were successful, but the electrical fluctuations were too weak to be detected accurately.
