This paper presents the experimental set-up, geometry and environmental conditions for pulsed channel soundings in the Mediterranean Sea.A short five-cycle pulse at a transmit frequency of 50 kHz is utilised to probe the ocean channel at a high repetition rate.The fast uctuations due to re ection and scattering are recorded on a transient analyser.The mean and coef cient of variation are used to analyse the pulsed response over a short period of time.Typical energy spreads induced by boundary re ection and scattering are in the region of 3 to 4 ms and could conceivably introduce inter-symbol interference in an underwater telemetry system where high bandwidth ef ciency is required.
