Year-long measurements by five acoustic Doppler current profiles moored across the central West Florida Shelf (WFS) and shelf break reveal new information on the local velocity structure and its temporal evolution. The moorings were between the 30 and 300 m isobaths. At depths greater than about 100 m the currents were sometimes directly affected by the deep ocean. During the measurement period the Loop Current (LC) directly impacted the central WFS three times, amounting to a total of about 13% of the year. For the remainder of the year the shelf break currents had equal likelihood of flowing northward or southward. Northward currents achieved over 70 cm/s and the southward currents (driven by the LC) achieved 120 cm/s. Neighboring instruments recorded strong (~30 cm/s) currents flowing in opposite directions. Current reversals, in one case totally nearly 100 cm/s within a few days, were also found. ¿ 2001 American Geophysical Union
