Electromagnetic fluctuations and turbulent vorticity fluctuations were measured over a nine month period in
the strong tidal flows of the Strait of Juan De Fuca off the coast of the Olympic Peninsula of Washington. A
collaborative experiment was designed to test the hypothesis that electromagnetic fluctuations at the sea
floor are forced by turbulent vorticity fluctuations in the bottom boundary layer. This report describes the
measurement of turbulent vorticity fluctuations and the associated analysis which focuses on testing existing
theoretical predictions for the inertial subrange and on characterizing spectra at frequencies below the
inertial subrange.
