A PREDICTION OF SONIC PROPERTIES OF DEEP-SEA CORES, SOHM ABYSSAL PLAIN AND ENVIRONS.
Abstract
Within the Sohm Abyssal Plain sand and coarse silt are major constituents of bottom deposits. These coarse layers are interstratified with clay. High impedence contrasts at the water-sediment interface and at textural breaks within the sediment section favor sound reflection at or immediately below the surface. Multiple sediment reflectors combined with a level sea floor suggest the plain offers an excellent acoustic interface for the reflection of sound. Reflectors are rare or absent in areas of abyssal hills south and east of the plain. These conclusions are based on inspection and analysis of piston cores. Predictions of sonic properties of individual cores are given. Select cores are matched to locations of acoustic stations completed under the Marine Geophysical Survey Program, U. S. Naval Oceanographic Office. (Author)
