Abstract : A collection of consecutive, detailed sound velocity profiles from 20 stations in the Bermuda-Barbados-Puerto Rico area is presented together with composite profile envelopes of sound velocity, and temperature for each station. These stations were taken during the months of April to July. The report emphasizes the variability of the sound channel, and its dependence on geographical location. A number of cell-like water masses, differing from the norm at the site, are pointed out. Since a number of stations included in this report were taken at sites investigated during a cruise 4 months earlier, a comparison of the sound channel parameters for November-December and April-May is included. The 4-month changes at these sites are found to be of about the same order of magnitude as short-term variations over each station alone. This report is a direct sequel to VOLUME I. of this series.
