Distribution of phytoplankton and other protists in the North Water
International audience Specific taxa and community structure of the phytoplankton and other protists in the North Water, a productive polynya ecosystem between Ellesmere Island (Canada) and Greenland, were determined from April to July 1998. Distinct temporal and spatial trends were observed within...

International audience Specific taxa and community structure of the phytoplankton and other protists in the North Water, a productive polynya ecosystem between Ellesmere Island (Canada) and Greenland, were determined from April to July 1998. Distinct temporal and spatial trends were observed within different geographic regions, influenced by water masses determined by temperature and salinity (TS) characteristics. In April, the northernmost communities were primarily flagellates and dinotlagellates, resembling those of the Arctic Basin, while large centric diatoms dominated in May and persisted through July.
