A case study on the application of the MSFD to Mediterranean coastal systems: the Po plume, as a transitional water system in the Northern Adriatic basin

摘要: 1 - In the frame of Marine Strategy Framework Directive (MSFD) European Community, in order to assess Good Environmental Status (GES) marine coastal and estuarine waters, eutrophication descriptors include several aspects phytoplankton communities (such as composition, abundance biomass). 2 Two oceanographic campaigns were carried out area off Po River plume, where a highly dynamic frontal zone separates an inshore offshore system. The coupling size structure diagnostic pigments relation different environmental contexts are tested expedite informative tool water quality sensu MSFD. 3 plume creates very zone, resulting strong trophic gradients within relatively small area. 4 spatio-temporal variability salinity waters transitional plays pivotal role structuring communities. 5 dynamics forcing factors drive changes cell-size structure, functional group composition well shift same group. 6 combination size-structure chemotaxonomic compositions is proposed for investigating, at appropriate scales, ecology systems.
