Long-Period Oscillations of the Ice Recorded by Continuous Gravimeter Measurements from Drift Station T-3

Аннотация

Describes an apparatus constructed by combining a North American 113 gravimeter and Kodak K-100 16 mm camera with which semi-continuous gravity observations were made on ice island T3 (Bravo) Jan-Mar 1960 in Beaufort Sea. The method by which the various components in the record were isolated is outlined, and it is concluded that vertical oscillations of the ice were detected, although their periodicity could not be determined exactly.
