Metabolic rates of freely diving Weddell seals: correlations with oxygen stores, swim velocity and diving duration
The metabolic rates of freely diving Weddell seals were measured using modern methods of on-line computer analysis coupled to oxygen consumption instrumen-tation. Oxygen consumption values were collected during sleep, resting periods while awake and during diving periods with the seals breathing at...
