The abundance and biomass of choanoflagellates and other nanoflagellates in waters of contrasting temperature to the north-west of South Georgia in the Southern Ocean.
The abundance and biomass of different categories of autotrophic and heterotrophic nanoflagellates were determined in surface waters along a transect crossing the Polar Front to the north-west of South Georgia in the Southern Ocean during the austral summer 1996. In the nanoflagellate community 14 c...

The most common choanoflagellates were Sicosta spinifera, Calliacantha spp., Diaphanoeca pedicellata and Parvicorbicula socialis.
