Fig. 4. Estimated blood and tissue N2 tensions
(PN2) during a single dive for a 12 kg king
penguin. Dive duration (133 s), dive depth (54 m) and surface interval (46 s)
were mean values of all dives during the foraging bout. Note that
PN2 for the fat compartment is on a different
scale. Initial conditions are those of model I in
Table 3.
