Important marine sectors for the top predator community around Kerguelen Archipelago
International audience The French Kerguelen Archipelago represents an important breeding place for many species of marine top predators within the Southern Ocean, making the plateau hosting the archipelago and surrounding waters (CCAMLR area 58.5) a crucial area to design conservation measures.
