The ecology and biogeography of tintinnid ciliates in the Atlantic sector of the Southern Ocean
Qualitative and quantitative analyses of the tintinnids retrieved in surface and vertical (down to 1150 m ) samples in the Scotia, Weddell, Bransfield and Bellingshausen areas allow us to define three distinct zones: (A) the Scotia Sea, Bransfield Strait and oceanic waters of the northern-central We...
