Abstract : The separations and velocities of separation between pairs of neutrally buoyant floats in pairs have been investigated in detail. Observations at three locations where the inertial periods are 18, 24 and 57 hours indicate strong relative movements around circles at those periods. Just within the Caribbean Sea, however, the motion is in a semidiurnal ellipse. Spectrums for the velocities of separation vary above the inertial frequency so that the energy density falls approximately as 1/f cubed. This decrease is consistent with the trend in the absolute velocities obtained at WHOI Mooring Site 'D' (UNESCO) at frequencies well above the inertial period. Correlations exist between the motions of nearby pairs of deep floats so that the motions are not entirely random. The possible effect of these on the spectra has yet to be investigated. (Author)
