The Eastern Bering Sea Shelf : oceanography and resources / edited by Donald W. Hood and John A. Calder . easternberingsea00hood Year: 1981 Northern fur seals 853 PHYSIOLOGY AND ECOLOGICAL RELATIONSHIPS Kooyman et ah (1976) reported an O2 consump- tion of ml ml/g-hr for subadult fur seals im- mersed in water at 6 C as controls in a study of the effect of oil fouling on physiology. This metabolic rate was measured over periods of activity and inactivity. The metabolic rate tended to increase as water temperature declined. Miller (1977) found comparable metabolic rates in immersed subadult fur seals and determined that there is no clear thermal neutral zone for fur seals from 1 to 25 C. Basal metabolic rate (BMR) was seldom reached in water colder than 24 C, and the metabolic rate showed a linear increase at temperatures below 20 C. In air between 0 and 20 C, a mean O2 consumption rate of ml ml/g-hr was obtained for postabsorptive resting subadult fur seals. This is assumed to be equivalent to the BMR for subadults and is twice the metabolic rate expected for a terrestrial mammal of comparable size (Miller 1977). Figure 52-4. Eastern Bering Sea. The operational area of researcii vessels is shaded. The numbers in each zone repre- sent, from left to right, number of boat days, seals seen, and seals collected from 1 July to 5 September 1963 (Marine Mam- mal Biological Laboratory 1965a).
