Objectif(s): Objectives were to: (1) test the hypothesis that ringed seals (Phoca hispida) are territorial under the sea ice; (2) determine the depths and durations of dives by free-swimming ringed seals; and (3) investigate the sensory components of under-ice navigation by free-swimming ringed seals.
Description du projet: This project is investigating the social organization, diving behaviour, and foraging patterns of ringed seals under the shore-fast ice. Trained dogs will locate the breathing holes and lairs of seals located beneath the snow. Sonic transmitters will be attached to the seals and monitored by way of 4 hydrophones lowered through the ice. The 3-dimensional locations of seals will be calculated, displayed and stored on micro-computers.
