Ice Fabric Studies on a 75m-Long Core Drilled at Mizuho Camp, East Antarctica
A 75m-long snow/ice core was drilled at Mizuho Camp, East Antarctica, by the glaciological members of the 12th Japanese Antarctic Research Expedition (1971-1972), and its density and the orientations of the c-axes of crystal grains composing it were measured immediately after recovery. It was found...
