We quantified the winter and spring movement patterns and foraging behavior of adult crabeater seals (Lobodon carcinophagus), and the influence of sea ice and bathymetry on their foraging behavior. Thirty-four seals (16 M 18 F) were outfitted with Satellite Relay Data Loggers (SRDLs) in the Marguerite Bay Region of the Antarctic Peninsula (� 671S, 671W) during the austral winters of 2001 and 2002. Tags transmitted position and dive information for between 4 and 174 days. Overall, winter… Expand
Ecology of Weddell seals during winter: Influence of environmental parameters on their foraging behaviour
Studying the foraging strategies of top predators can provide information on both how animals interact with their environment and the distribution of their prey. We studied the winter foragingExpand
Fine-scale habitat selection of crabeater seals as determined by diving behavior
Previous studies within the Marguerite Bay region of the Antarctic Peninsula ( 671S, 671W) demonstrated that during winter, crabeater seals (Lobodon carcinophagus) were not randomly distributedExpand
Fine-scale habitat selection of crabeater seals as determined by diving behavior
Abstract Previous studies within the Marguerite Bay region of the Antarctic Peninsula (∼67°S, ∼67°W) demonstrated that during winter, crabeater seals (Lobodon carcinophagus) were not randomlyExpand
Projected shifts in the foraging habitat of crabeater seals along the Antarctic Peninsula
Crabeater seals exhibit extreme dietary specialization, feeding almost exclusively on Antarctic krill. This specialization has inextricably linked habitat use, life history and evolution of thisExpand

Characterization of winter foraging locations of Adélie penguins along the Western Antarctic Peninsula, 2001-2002
In accord with the hypotheses driving the Southern Ocean Global Ocean Ecosystems Dynamics (SO GLOBEC) program, we tested the hypothesis that the winter foraging ecology of a major top predator inExpand
Foraging habitats of southern elephant seals, Mirounga leonina , from the Northern Antarctic Peninsula
Abstract Elephant Island (EI) is uniquely placed to provide southern elephant seals (SES) breeding there with potential access to foraging grounds in the Weddell Sea, the frontal zones of the SouthExpand
Distribution and diving behaviour of crabeater seals (Lobodon carcinophaga) in the Weddell Sea
The crabeater seal (Lobodon carcinophaga) is the most abundant seal worldwide and inhabits the circumpolar pack ice zone of the Southern Ocean. Around half of its population is found in the WeddellExpand
Diving physiology and winter foraging behavior of a juvenile leopard seal (Hydrurga leptonyx)
TLDR
The shallow diving behavior of a juvenile leopard seal contradicts previous diet research suggesting Antarctic krill is the primary prey of leopard seals during the winter months as krill were found at deeper depths during this period. Expand
Crabeater seal diving behaviour in eastern Antarctica
Southern Ocean waters are highly productive and contain important food resources for many indigenous predators, including humans. Management of these resources has fallen under the regulation of theExpand

Foraging behaviour of antarctic fur seals during periods of contrasting prey abundance
TLDR
It is demonstrated that female fur seals invest a significantly greater effort in foraging during periods of low prey abundance by both increasing the time spent foraging and by increasing activity during foraging. Expand

Distribution and diving behaviour of crabeater seals (Lobodon carcinophagus) off Queen Maud Land
TLDR
The notion that crabeater seals predominantly feed on krill in Antarctic pack ice, even when winter returns to the waters off Queen Maud Land, is supported. Expand
Notes on winter feeding of crabeater and leopard seals near the Antarctic Peninsula
TLDR
Analysis of stomach contents of crabeater and leopard seals collected in the pack ice west of the antarctic Peninsula in August–September 1985 suggest that krill were not abundant or widely distributed in the area at the time the seals were collected. Expand
Diet and foraging effort of Adélie penguins in relation to pack-ice conditions in the southern Ross Sea
TLDR
Successful foraging during chick rearing, the period when adult foraging is most intense, appears to depend on the proximity of pack ice to nesting colonies for this penguin species. Expand
Diving and haulout behavior of crabeater seals in the Weddell Sea, Antarctica, during March 1986
TLDR
It is suggested that the distinct diel pattern of dive timing and depth may be related to possible predator avoidance behavior by the seals' principal prey, Antarctic Krill. Expand

THE emperor penguin (Aptenodytes forsteri), which feeds only at sea, is restricted to the higher latitudes of the antarctic sea-ice habitat1–3. It breeds on the winter fast ice when temperaturesExpand
Foraging ecology of southern elephant seals in relation to the bathymetry and productivity of the Southern Ocean
TLDR
It is suggested that the physiological requirements of feeding and digestion reduced the aerobic dive limit of elephant seals, and long distance travel to relocatable hydrographic or topographical features, such as shelf breaks, may allow large predators to locate prey more consistently than from mid-ocean searches.

TLDR
