ON GEOACOUSTIC INHOMOGENEITIES OF THE DEE P-OCEAN BOTTOM

Some results of a detailed investigation of the spatial variability of geoacoustic inhomogeneities of the deep ocean bottom for zones of the hilly relief are presented. Much attention was paid to regions of bot tom covered by the manganese nodules. Measurements of the geological p arameters were carried out with a very high resolution (discreteness e quals to tens or even units of meters) for ranges of 10 - 15 km. Very intensive spatial variability of the geological characteristics was fo und, and variability of the acoustic field reflected from such an inho mogeneous bottom was calculated.
