Description. Weddell seals measure about 2.5–3.5 m (8 ft 2 in – 11 ft 6 in) long and weigh 400–600 kg (880–1,320 lb). [5][6] They are amongst the largest seals, with a rather bulky body and short fore flippers relative to their body length. [7] Males weigh less than females, usually about 500 kg (1,100 lb) or less.
Weddell Sea Bottom Water (WSBW) is a subset of Antarctic Bottom Water (AABW) that is at a temperature of -0.7 °C or colder. It consists of a higher salinity branch and a lower salinity branch. It originates in the Weddell Sea and closely follows the sea floor as it flows out into the rest of the world's oceans.
Weddell got as far south as 74°S; the furthest southern penetration since Weddell but before the modern era was made by William Speirs Bruce in 1903. The Weddell Sea is an important area of deep water mass formation through cabbeling, the main driving force of the thermohaline circulation. Deepwater masses are also formed through cabbeling in ...
Hauling out is a behaviour associated with pinnipeds (true seals, sea lions, fur seals and walruses) temporarily leaving the water. [1][2] Hauling-out typically occurs between periods of foraging activity. [1][3][4] Rather than remain in the water, pinnipeds haul out onto land or sea ice for reasons such as reproduction and rest. [4][2] Hauling ...
The crabeater seal (Lobodon carcinophaga), also known as the krill-eater seal, is a true seal with a circumpolar distribution around the coast of Antarctica. They are the only member of the genus Lobodon. They are medium- to large-sized (over 2 m in length), relatively slender and pale-colored, found primarily on the free-floating pack ice that ...
All lobodontine seals have circumpolar distributions surrounding Antarctica. They include both the world's most abundant seal (the crabeater seal) and the only predominantly mammal-eating seal (the leopard seal). While the Weddell seal prefers the shore-fast ice, the other species live primarily on and around the off-shore pack ice. Thus ...
Earless seal. The earless seals, phocids, or true seals are one of the three main groups of mammals within the seal lineage, Pinnipedia. All true seals are members of the family Phocidae (/ ˈfoʊsɪdiː /). They are sometimes called crawling seals to distinguish them from the fur seals and sea lions of the family Otariidae.
The International Weddell Sea Oceanographic Expeditions or IWSOE are a series of scientific research expeditions to the Weddell Sea began in 1967, involving cooperation among Norway, Canada, Chile and the United States. Weddell Sea ice formation (Shackleton expedition 1916) The Weddell Sea, part of the Southern Ocean, is a unique scientific ...
