Micromonas pusilla (Prasinophyceae) as part of pico-and nanoplankton communities of the Barents Sea

Abstract

Micromonas pusilla (Butcher) Manton & Parke appears to be a prominent member of the Barents Sea picoplankton community as revealed by the serial dilution culture method. Cell numbers frequently exceeded 107 cells 1?1, though they usually varied between 103and 106 cells l?1. A number of other identified and unidentified taxa were recorded and quantified. Distribution relative to the marginal ice zone is reported.
