The '''[[southern elephant seal]]''' (''Mirounga leonina'') is one of the two species of elephant seals. It is the largest member of the clade Pinnipedia and the order Carnivora, as well as the largest marine mammal that is not a cetacean. It gets its name from its massive size and the large proboscis of the adult male, which is used to produce very loud roars, especially during the breeding season. A bull southern elephant seal is about 40% heavier than a male northern elephant seal (''Mirounga angustirostris''), more than twice as heavy as a male walrus (''Odobenus rosmarus''), and six to seven times heavier than the largest living terrestrial carnivorans, the polar bear (''Ursus maritimus'') and the Kodiak bear (''Ursus arctos middendorffi'').
'''[[Moore Dome]]''' (74°20′S 111°20′W) is an ice dome, circular in plan and 15 nautical miles (28 km) in extent, rising to 700 meters (2,300 ft) and forming the northwest portion of the [[Bear Peninsula]], along [[Westarctica]]'s [[Walgreen Coast]]. [[Koloc Point]] is at the northern extremity of the coast of the dome.


Tracking studies have indicated the routes traveled by elephant seals, demonstrating their main feeding area is at the edge of the Antarctic continent. While elephant seals may come ashore in [[Antarctica]] occasionally to rest or to mate, they gather to breed in subantarctic locations.
Moore Dome was mapped by the United States Geological Survey from aerial photographs taken by [[U.S. Navy]] Operation Highjump in 1947 and the U.S. Navy in 1966. It was named by the Advisory Committee on [[Antarctic]] Names in 1977 after Captain Robert G. Moore, USCG, Commanding Officer of USCGC ''Burton Island''. The ''Burton Island'' conducted operations in the [[Ross Sea]], [[Pine Island Bay]], and along the [[Antarctic Peninsula]] during the 1974–75 season.

Moore Dome (74°20′S 111°20′W) is an ice dome, circular in plan and 15 nautical miles (28 km) in extent, rising to 700 meters (2,300 ft) and forming the northwest portion of the Bear Peninsula, along Westarctica's Walgreen Coast. Koloc Point is at the northern extremity of the coast of the dome.

Moore Dome was mapped by the United States Geological Survey from aerial photographs taken by U.S. Navy Operation Highjump in 1947 and the U.S. Navy in 1966. It was named by the Advisory Committee on Antarctic Names in 1977 after Captain Robert G. Moore, USCG, Commanding Officer of USCGC Burton Island. The Burton Island conducted operations in the Ross Sea, Pine Island Bay, and along the Antarctic Peninsula during the 1974–75 season.
