Abstract

"In general, Antarctica is bordered by a deposit of glacial marine sediment which roughly coincides with the area of pack ice; the next zone to the north contains diatom ooze which extends northward to the position of the Antarctic convergence or to the line where the Antarctic surface water turns under normal open ocean water. North of the convergence, in the open ocean, the bottom sediment is red clay in the deeper water and a calcareous ooze in the shallower water. Near shores, 'terrigenous' sediments of various kinds are found."
