Microzooplankton along a transect from northern continental Norway to Svalbard
In the framework of the Italian International Polar Year project entitled Evolution of a Glacial Arctic Continental Margin: the Southern Svalbard Ice Stream-dominated Sedimentary System, a study was carried out on microzooplankton distribution and biomass along a south-to-north transect extending fr...

In the framework of the Italian International Polar Year project entitled Evolution of a Glacial Arctic Continental Margin: the Southern Svalbard Ice Stream-dominated Sedimentary System, a study was carried out on microzooplankton distribution and biomass along a south-to-north transect extending from northern Norway to the Svalbard Archipelago, from 65° to 78°N. Tintinnids, heterotrophic dinoflagellates, aloricate cilates and micrometazoans were the main groups observed in the samples collected at 17 surface stations from 9 to 13 July 2008. Total microzooplankton abundance ranged from 17 to 438 ind l−1. Tintinnids and heterotrophic dinoflagellates were the most abundant organisms, ranging from 1.5 to 292.5 ind l−1 and from 0 to 232 ind l−1, respectively.
