Abstract : An underwater acoustics experiment conducted in shallow water (70 feet) off the New Zealand east coast in 1972-1973 is described. Short acoustic pulses of 35 and 65 kHz sound were projected along near-orthogonal paths of approximately 300 yards. Environmental parameters were simultaneously observed. Statistical and spectral analyses of pulse heights were performed on 12 selected runs using digital techniques. Microscale temperature fluctuations measured simultaneously are discussed.
