New insights into prime Southern Ocean forage grounds for thriving Western Australian humpback whales
Humpback whale populations migrate extensively between winter breeding grounds and summerfeeding grounds, however known links to remote Antarctic feeding grounds remain limited in manycases. New satellite tracks detail humpback whale migration pathways from Western Australia intothe Southern Ocean....
