Two sampling campaigns per year target pelagic ecosystems at depths from 0 to 200 meters. The objectives are to examine the use of different components of the plankton assemblages (phytoplankton and zooplankton), to assess the biodiversity status, to explore the possibility to set threshold values for those components in relation to ecologically relevant assessment areas, to improve the coherence of Good Ecological Status (GES) definition for the MSFD.
