Oceans and seas cover more than 70 % of the Earth and hold extraordinarily rich
biodiversity, right down to great depths where abundant life forms thrive near ocean ridges. But marine biodiversity remains poorly known and faces numerous threats. Endangered by ever-increasing pressures from human activities, it is also sensitive to climate-based disturbances, in particular their consequences on ocean acidification.
