dc.description.abstract	Some recent experimental developments relating to internal oceanographic- acoustic interactions are reviewed. Besides amplitude and phase fluctuations, a major concern is scattering into shadow regions. Associated oceanographic phenomena may include shear currents, turbulence and internal waves and upwelling. Experimental data show frequency independence of both scatter into shadow zones and leakage from sound channels. Propagation over sea mounts also shows the dominance of oceanographic refraction over diffraction. Preliminary results of an experiment involving a large ocean eddy are discussed.
