| Summary: | The Continuous Plankton Recorder (CPR) survey has been deployed since 1931 to describe and analyze plankton variability in the North Atlantic and North Sea. This survey measures the presence and abundance of 437 phytoplankton and zooplankton taxa and provides an assessment of phytoplankton biomass, the Phytoplankton Colour Index (VCI). The diatoms and dinoflagellates are the two main phytoplankton groups identified by the CPR survey. The first part of this work provides insights into the space-time dynamics of phytoplankton communities through an analysis of diatom and dinoflagellate populations in the whole North Atlantic basin. Because the North Atlantic Ocean includes many different biotopes, the second part focuses on the mesoscale variability of phytoplankton species. The long-term fluctuations of the phytoplankton species are studied in the NW and in the NE Atlantic, the two best sampled areas of the CPR survey. In the NE Atlantic, the aim is to determine the contribution of the diatoms and ... |
