Abstract:

Operation Ghubbet was conducted between 7 and 25 September 1971 jointly with Naval Underwater Systems Center, New London and the French Navy based at Djibouti, T.F.A.I. The principal objectives of the project were to investigate the acoustic properties and the associated water characteristics in the area of the sill separating the Red Sea from the Gulf of Aden. Because of the unusual oceanographic properties in the Strait of Bab-El-Mandeb and in the vicinity of the Hanish Islands, part of the project Phase I was devoted to determining, in detail, parameters that would influence sound propagation. Phase II used two ships to measure sound propagation in four different experimental situations.
