Seasonal acoustic occurrence, diel‐vocalizing patterns and bioduck call‐type composition of Antarctic minke whales off the west coast of South Africa and the Maud Rise, Antarctica

Seasonal occurrence, diel‐vocalizing patterns, and call‐types of Antarctic minke whales are described using bio‐acoustic recordings from the west coast of South Africa and the Maud Rise, Antarctica. In Antarctica, minke whale bioduck calls were detected in seven of nine months of hydrophone deployment (peaking in May and September) while downsweeps were only detected in June. Bioduck calls were sporadically detected in South African waters with...
