Abundance and Biodiversity of Top Predators-Seabirds and Marine Mammals in Antarctic Seas
Abstract
Claude R. Joiris
This article concerns the comparison of data collected in different Antarctic seas by the same team, same platform (mainly from the bridge of icebreaking RV Polarstern, 18 m above sea level), and thus the same methodology. Drastic differences were noted, from very high numbers in the Weddell Sea to very low ones in the Amundsen Sea. Biodiversity was low, as reflected by low numbers of species, a few of them representing the vast majority in numbers of individuals: between 85% and 95% of the total.
