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. Micrometazoans (mainly copepod nauplii) reached a maximum of 45.5 ind l⁻¹, whereas aloricate ciliates were scarce at all stations. Microzooplankton carbon content ranged from 0.87 to 5.18 μg C l⁻¹. In particular, tintinnids and micrometazoans made up the largest part of the microzooplankton biomass. Parafavella denticulata, <em>Parafavella gigantea, Acanthostomella norvegica</em> and <em>Ptychocylis obtusa</em> were the most common species among tintinnids, whereas <em>Leprotintinnus pellucidus</em> was recorded in only one station close to Svalbard. <em>Protoperidinium</em> was the most representative genus among heterotrophic dinoflagellates. The community of naked ciliates was dominated by <em>Strombidiidae</em> and <em>Holotrichia</em>. A clearly increasing gradient in both abundance and number of taxa was observed from south to north, with the temperature decreasing from 13.3 to 2.5°C.</p><p><strong>Keywords:</strong> Microzooplankton; North Atlantic Current; Svalbard; tintinnids; dinoflagellates</p><p>(Published: 24 May 2013)</p><p><strong>Citation:</strong> Polar Research 2013, <strong>32</strong>, 19306, <a href="http://dx.doi.org/10.3402/polar.v32i0.19306" target="_blank">http://dx.doi.org/10.3402/polar.v32i0.19306</a></p&gt;}, journal={Polar Research}, author={Monti Marina and Minocci Marco}, year={2013}, month={May} }
