Fig. 1. (A) Example of the cumulative pause duration versus the cumulative dive
duration for a dive sequence (B) of a single imperial cormorant foraging in
water between 10 and 50 m deep. Note that the steeper slope of the gradient in
deeper waters is not as obvious as it otherwise might be because the
presentation of the cumulative values irons out a great deal of variability in
single pause versus dive duration values.
