The U.S. Naval Oceanographic Office NAVOCEANO was requested by the Naval Research Laboratory NRL to provide oceanographic support for an underwater acoustic experiment during July and August 1969. The experiment was conducted about 15 miles southwest of Panama City, Florida, from USNS J.W. Gibbs T-AGOR 1. The objective of the NAVOCEANO survey was to determine the sound speed of the water column when requested by NRL. NAVOCEANO data were collected from 14 Nansen stations, 26 velocimeter lowerings, 77 bathythermograph lowerings, and 2 bottom samples. Sound speeds were computed from temperature and salinity data and measured with a velocimeter. Agreement between the two methods was generally good. The measured parameters revealed a continuously changing water column during the survey. Minimum sound speeds fluctuated about 7 msec from the beginning to the end of the survey.
