Two-year records of temperature and current from a single subsurface mooring are demonstrated to be representative of the fluctuation spectrum of the Florida Current for time scales of several days to one or more years. The dominant subinertial motions occur in three period bands: from 8 to 25 days, 4 to 5 days, and 2 to 3 days. Simultaneous observations in a crossstream array reveal energy maxima in the same bands for all locations....
