Accuracy of ARGOS Locations of Pinnipeds at-Sea Estimated Using Fastloc GPS
Background ARGOS satellite telemetry is one of the most widely used methods to track the movements of free-ranging marine and terrestrial animals and is fundamental to studies of foraging ecology,Expand
Effects of buoyancy on the diving behavior of northern elephant seals.
TLDR
It is demonstrated that buoyancy plays a significant role in shaping diving behavior in northern elephant seals and that elephant seals may adjust their behavior to suit their buoyancy, rather than adjusting their buoyancies to suit a dive. Expand
FORAGING ECOLOGY OF NORTHERN ELEPHANT SEALS
Sexual segregation in foraging is predicted from the great size disparity of male and female northern elephant seals, Mirounga angustirostris. Our aim was to test this prediction by measuring divingExpand
Drift diving in female northern elephant seals: implications for food processing
TLDR
Predictions from the hypothesis that northern elephant seals drift during the bottom segment of some dives (called C dives) using oxygen saved from reduced locomotion to process food are tested. Expand
Interpolation of animal tracking data in a fluid environment
TLDR
This work interpolated tracking data from albatrosses, penguins, boobies, sea lions, fur seals and elephant seals using six mathematical algorithms, choosing Bézier, hermite and cubic splines, in addition to a commonly used linear algorithm to interpolate data. Expand
Winter habitat use and foraging behavior of crabeater seals along the Western Antarctic Peninsula
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.Expand
Autonomous Pinniped Environmental Samplers: Using Instrumented Animals as Oceanographic Data Collectors
Data-recording tags applied to marine animals store data for later retrieval and can return valuable information on animal behavior and ecology, including habitat preference, physiology, and movementExpand
Energy reserve utilization in northern elephant seal (Mirounga angustirostris) pups during the postweaning fast: size does matter
TLDR
It is suggested that body composition at weaning influences lipid utilization patterns and ultimately the duration of the postweaning fast in northern elephant seal pups, and percentage lipid content increased with body mass, and fatter pups utilized lipid at relatively higher rates during the fast. Expand
MATERNAL TRAITS AND REPRODUCTIVE EFFORT IN NORTHERN ELEPHANT SEALS
TLDR
Maternal size, body composition, and age were important features of reproduction in northern elephant seals, and these characteristics are rarely considered concurrently in life history studies. Expand
Blood Volume and Diving Ability of the New Zealand Sea Lion, Phocarctos hookeri
TLDR
New Zealand sea lions have the highest blood volume yet reported for an otariid, which supports the hypothesis that they have a physiological capability suited to their unique diving behavior. Expand
