Automatic Processing of Arctic Pack Ice Data Obtained by Means of Submarine Sonar and Other Remote Sensing Techniques.
Automatic processing and analysis of three types of remote sensing data of arctic pack ice are described. The primary emphasis is on upward-looking sonar profiles of the underside of pack ice obtained during the winter 1960 arctic cruise of the SSN 583, SARGO. Two traverses, one in the Chukchi Sea a...
