A satellite buoy experiment, which was conducted during COBLAMED in the Western Mediterranean, consisted of a thermistor buoy tethered to an identical moored buoy in a mean current at separation distances of 100 and 400 m in order to observe the dependence of small scale variability upon internal waves and advection and to register time and depth variability of horizontal coherence. The two 18-hour records showed distinct warm and cold pulses which traversed the separations with the mean current and preserved their shapes....
