  • Abstract Abstract. Diving behaviour of four lactating harp seal females was recorded using time-depth recorders. The females spent 20·6 ± 3·8% (X ± SD) of their time hauled out on the surface of the ice, 34·2 ± 2·5% of the time in the water in a surface position, and 45·2 ± 5·9% of the time diving. A total of 3701 dives were recorded with a mean duration of 3·2 ± 2·4 min. The maximum dive duration recorded was 13 min and maximum recorded depth was 90 m. Only 0·6% of the dives exceeded the… CONTINUE READING
