'''[[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.

The southern elephant seal 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.

The world population was estimated at 650,000 animals in the mid-1990s, and was estimated in 2005 at between 664,000 and 740,000 animals. Studies have shown the existence of three geographic subpopulations, one in each of the three oceans. 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.
