    Over 200,000 km of precision soundings and 8,000 bottom photographs (440 stations) were obtained by the USNS Eltanin in the Bellingshausen Sea. The rocky crest of the Mid-Oceanic Ridge in the western Bellingshausen Sea is dextrally displaced 1,000 km by the Eltanin Fracture Zone. The Bellingshausen Abyssal Plain lies at the base of a wide continental rise. South of the polar front, muddy bottom is seen in nearly all photographs, whereas to the north both ridge and basin photographs show either scattered rocks, outcrops (pillow lava), or nodules. Boulders occur beneath the pack ice and north of the front. Anomalously smooth bottom showing weak to strong scour lies between the pack limit and the front and demonstrates the presence of significant bottom currents. Manganese nodules north of the front become larger and more numerous from west to east, and finally give way to strong scour and ripples (greater than 4,000 m) in the constricted Drake Passage.
