Annual and diurnal variations in the underwater vocalizations of Weddell seals

Summary

Weddell seal vocalizations were recorded once a fortnight throughout 1984 at a major pupping site near Davis, Antarctica. Few vocalizations were heard between January and June. The number of vocalizations recorded increased from July to a peak in November and early December during the breeding period and then fell off rapidly through December. The increase in the number of seal vocalizations was correlated with a build up in seal numbers but some of the increase may be explained by an increased rate of vocalization by males.
