Sound speed profiles are presented for more than fifty sound velocimeter lowerings made in the Tongue of the Ocean (TOTO) and Exuma Sound, Bahamas in February and March, 1962. A comparison of the velocimeter data and sound speeds derived from non-synoptic oceanographic station data for the same observation period indicates good agreement between the two methods. Time variability of profiles was greatest at depths of from 200 to 1000 meters and appeared to be more pronounced than spatial variability. The depth of the sound speed maximum was found to increase in a southward direction in the TOTO and to be generally shallower in Exuma Sound. Fixed-depth time variability of sound speed in Exuma Sound differed slightly from that in the TOTO. (Author).

Normal incidence bottom reflection loss measurements at 12-kc were conducted from the USS PREVAIL (AGS-20) in the Tongue of the Ocean and Exuma Sound, Bahamas during July through August 1963. Approximately 8000 second bottom reflections were recorded over the 700 miles of tracks steamed in the combined area. The measurements were made underway with an AN/UPN-1 echo sounder and a modified REMPAC system. The effect of the marginal slopes in the Tongue of the Ocean on increasing bottom loss values was investigated. Minimizing this effect allowed a more realistic comparison of the Tongue of the Ocean and Exuma Sound data. Results indicate both areas have nearly identical mean bottom loss (19.1 db and 19.2 db) which compare favorably with corrected AMOS data. (Author).
