Recent Iceberg-Rafted and Cryophilic Biogenic Deposits of Antarctica

Bottom sediments affected by “ice mountains” or icebergs occupy even larger areas in the World Ocean than the sea ice-rafted deposits. Only in the Antarctic are icebergs spread over the area of 60-65 million km2, i.e. the area is 5 times as great as the Arctic Ocean (Table 10.1). The second large area of iceberg-rafted deposits is situated in the Northern Hemisphere (Davis Strait, western and eastern coasts of Greenland, regions stretching southward from Greenland to Newfoundland). The area of iceberg-rafted deposits in this part of the ocean is 1.41 million km2.
