Evaluating the changes on the environmental status of Mediterranean ecosystems

In this work we use an integrated modelling approach including atmospheric forcing, land-sea interactions and a hydrodynamic-biogeochemical ocean model to evaluate the causes of observed and simulated coastal eutrophication indices in different regions of the northern Mediterranean Sea. By controlling the chemical characteristics of the rivers´ waters we evaluate the role of each major inorganic nutrient in fostering pelagic primary production and bottom hypoxic conditions in the nearby systems. Different nutrients seem to be controlling these eutrophication indicators in diverse regions, which have implications for the managing options for the different rivers´ catchment areas. Then, we evaluate the evolution of the eutrophication indicators under different future climatic scenarios. Combining the results from the ensemble climatic simulations, we can estimate probable trajectories of the ecosystems in the future and, thus, help in the implementation of adaptation and mitigation policies.
