In an underwater acoustic propagation experiment conducted in November 1970 a periodic broadband signal, centered about 420 Hz, was transmitted across the Straits of Florida continuously for 19 days. This report presents the preliminary results from spectral analysis of the acoustic reception of this signal at Bimini, Bahamas, during a 7.61-hour period on 25 November 1970. The spectra are noteworthy for their slow rate of change during this period. Plots of the spectral amplitude and phase of the reception are presented for a 50 Hz bandwidth centered about 420 Hz.
