...Michael A. De Miranda, Jr; Amber E. Schlater; Todd L. Green; Shane B. Kanatous SUMMARY A key cellular adaptation to diving in Weddell seals is enhanced myoglobin concentrations in their skeletal muscles, which serve to store oxygen to sustain a lipid-based aerobic metabolism. The aim of this study...

... that simulated aerobic dives in a Weddell seal( Leptonychotes weddellii ) and ran it for four Mb concentrations: 5,27, 54 and 108 g Mb kg –1 muscle representing 7%, 50%, 100%and 200%, respectively, of the normal Mb concentration in Weddell seal skeletal muscle. The model was run at increasing levels of muscular...

... basic hypotheses are examined by computer simulation, using a mathematical model of the mammalian cardiorespiratory control system with parameter values for an adult Weddell seal: (1) that the control of diving can be considered to be a respiratory control problem, and (2) that dives are initiated...

... costs in a free-ranging marine mammal, we measured the post-dive oxygen consumption of adult Weddell seals ( N =9) performing foraging and non-foraging dives from an isolated ice hole in McMurdo Sound, Antarctica. Dives were classified according to behavior as monitored by an attached video-data logging...

... deplete oxygen reserves,leading to the termination of a dive. We investigated the swimming behavior of eight adult Weddell seals, which are proficient divers, in McMurdo Sound,Antarctica. A newly developed data logger was attached to free-ranging females at their own breeding sites to record swimming...
