Electronic Supplement to "SEASONAL AND DIEL CYCLES OF FIN WHALE ACOUSTIC OCCURRENCE NEAR ELEPHANT ISLAND, ANTARCTICA" from Seasonal and diel cycles of fin whale acoustic occurrence near Elephant Island, Antarctica
This study investigates the relevance of the Elephant Island (EI) region for Southern Hemisphere fin whales ( Balaenoptera physalus ) in their annual life cycle. We collected 3 years of passive acoustic recordings (January 2013 to February 2016) northwest of EI to calculate time series of fin whale...
