SONIC PROPERTIES OF DEEP SEA CORES FROM THE NORTH PACIFIC BASIN AND THEIR BEARING ON THE ACOUSTIC PROVINCES OF THE NORTH PACIFIC.
Two hundred and fifty long piston cores of deep-sea sediments from the North Pacific have been analyzed and predictions of their acoustic properties are given. Maps are included that outline submarine physiography, and the regional distribution of turbidites, volcanic ashes and sub-bottom reflecting...
