Table 2 Summary dive statistics for all study individuals

From: An animal-borne active acoustic tag for minimally invasive behavioral response studies on marine mammals

  1. Age was either known from initial tagging as a pup or estimateda in the field based on standard length and weight. Sex was assessed and body mass was measured before instrumentation. Deployment duration was dependent on the time it took the seal to return to the beach. Number of dives recorded includes all instances where the animal dove deeper than 4 m. Mean (and SD) dive duration, in min, are given for all dives and the subset of dives deeper than 100 m
