Current Meter Data from the Southeastern Caribbean Sea, August 1978 to February 1979.
Abstract
Thirteen vector-averaging current meters were deployed on four moorings in the southeastern Caribbean Sea from August 1978 to February 1979. Velocity and temperature data are presented graphically as time series, histograms, and as variance spectra. Low-pass filtered data (72 hour period at the half-power point) are presented graphically as progressive vector diagrams, vector diagrams (stick plots), time series, and spectra. Scalar mean speeds ranged from 4 to 38 cm/s, and (mostly westward) vector mean speeds from 2 to 36 cm/s (all but one were less than 9 cm/s). The velocity and temperature variance were distributed among three frequency bands: subinertial, inertial, and tidal. In the velocity spectra the subinertial variance accounted for an average of 50% of the total variance, inertial 5%, and tidal 10%. In the temperature spectra the subinertial accounted for 75% of the total variance, inertial 1%, and tidal 10%. Individual records had peaks at periods between 10 and 45 days. (Author)
