Current in the upper 60 m in the western Mediterranean displayed dominant inertial character strongly modulated by wind changes, which also altered the mean flow. Kinetic energy variations associated with the current at 60 m corresponded with gross changes in wind and sea state and were equivalent to observed kinetic energy changes associated with coastal tides. Current records from a slowly drifting buoy were similar to fixed buoy records. Kinetic energy spectra indicated a −5/3 power frequency dependence. Spectral coherence was high for both vertical and horizontal separation, with the vertical motions strongly out of phase and the horizontal strongly in phase.
