Abstract : During 16-18 May 91, an active acoustics exercise was conducted under the auspices of the Program Executive Office of the Air, ASW, Assault and Special Missions Programs office on the continental shelf between St. Thomas, U.S.V.I. and the Puerto Rico Trench. The objective of this mission is to make noise, reverberation and transmission loss measurements using fully calibrated sources, receivers and recording devices. This data set is intended to support the validation of candidate shallow water transmission loss and reverberation models for use in the development of next generation airborne ASW sensor systems. To adequately interpret the exercise results and to support the modeling effort, a robust suite of supporting environmental measurements were made aboard the R/V Acoustic Explorer. These measurements include a depiction of the sound speed structure, geophysics, bathymetry, meteorological conditions and navigation along 5 projector tow tracks and at 6 drifting ambient noise-reverberation sites. This technical note provides a brief description of the oceanographic and geological structure in the exercise area followed by a compendium of the collected data.
