Normal Incidence Bottom Reflection Measurements in the Tongue of the Ocean and Exuma Sound, Bahamas.

Abstract

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)
