This stretch of the Southern Ocean, in the Central South Pacific sector, is a summer feeding ground for the humpback whales that breed across Oceania, such as Tonga, Niue and French Polynesia. From November to March, they gorge on dense Antarctic krill in these cold, remote waters before migrating thousands of kilometres north to warm tropical breeding grounds. There is no tourism here: the whales are seen mainly through research and the occasional expedition ship.
