Geographical variation of harp seal underwater vocalizations
Underwater vocalizations of harp seals (Phoca groenlandica) were recorded during the breeding season in the Gulf of St. Lawrence and north of Jan Mayen Island. Each herd had one unique call type and shared (often in different proportions) an additional 17 call types. Of these 17, 13 common call type...
