Diving behaviour of chick-rearing Adélie Penguins at Edmonson Point, Ross Sea
International audience The diving behaviour of chick-rearing Ade´lie penguins of Edmonson Point, Ross Sea, was analysed over two summer seasons (1994–1995 and 1995–1996). In 1994–1995, the study area was characterized by fast-ice persistency throughout season and by higher pack ice concentration tha...
