Note(s): Current and wind data collected during the summer of 1992 and the fall and winter of 1993–1994 are used to characterize near-bottom flow patterns at a study site in Hawk Channel southwest of Key West. Currents are dominated by along-channel motions with low-frequency reversals occurring over time scales of 2–3 weeks. A seaward deflection of along-channel flow is apparent in both records. Harmonic analysis indicates that tidal co-oscillations contribute 6–10% and 48–70% of the total variance of the along-channel and across-channel currents, respectively. Spectral analysis indicates a close coupling between along-channel wind stress and along-channel currents at periodicities of 2–3 days. A comparison of across-channel winds and across-channel currents suggests an inverse relationship indicating an upwind return flow of near-bottom currents.
