Community structure and spatial distribution of benthic fauna in the Bellingshausen Sea (West Antarctica).
International audience The structure and spatial distribution of the macrofauna community of the Bellingshausen Sea in the western sector of Antarctica was studied during the ‘BENTART–06' oceanographic expedition. This is one of the least explored Antarctic seas. A total of 20 box cores were sa...
