Abstract:

The BEARING STAKE exercise was conducted in the Northwest Indian Ocean from January to May 1977 with preliminary bathymetric surveys being conducted from October through December 1976. The objectives of the exercise were to conduct acoustic measurements of the area utilizing near-surface, mid- water, and bottom-mounted receivers to determine the following acoustic parameters 1 Propagation loss versus frequency, depth, range 2 Omnidirectional ambient noise 3 Ambient noise directionality 4 Wavefront coherence 5 Vertical arrival structure 6 Bottom interaction and 7 Bottom reflectivity.
