| L’objectif de cette étude est de mettre en évidence et de hiérarchiser les pressions anthropiques ayant le plus d’impact sur les éléments de qualité DCE sur les lagunes méditerranéennes et de consolider ainsi les liens état/pressions. Il s’agit également de mettre en évidence des groupes de masses d’eau homogènes en termes de pressions. Ce travail s’appuie sur les précédentes études menées sur le sujet (Battut, 2010 ; Bouchoucha et al., 2010 ; Meinesz et al., 2013) et vise à les compléter grâce : • à la mise en œuvre d’une approche descriptive multidimensionnelle qui permet de mettre en évidence les interactions entre les différentes métriques de pression et d’état et de regrouper les masses d’eau similaires, • à l’intégration de données de pression et... |

| Within the European water framework directive (WFD), the status assessment of littoral waters is based both on the chemical quality and on the ecological quality of each water body. Quality elements enabling to assess the ecological status of a water body are, among other things, biological quality elements (phytoplankton, macroalgae, angiosperms, benthic invertebrates, fish), for each of which member states have developed quantitative indicators. This document compiles three deliverables of a multi-annual study intended to characterize the sensitivity of these biological indicators regarding the various anthropogenic pressures exerted on the French Atlantic and Channel coast: ultimately, the goal is to establish a quantitative and predictive relationship,... |

| In order to establish the ecological status of water bodies, the European Water Framework Directive (WFD) is based on the evaluation of a number of biological quality elements, as well as physical parameters supporting the biology. In estuaries, phytoplankton monitoring was not considered relevant because of the high turbidity characterizing the large metropolitan estuaries and the French overseas departments (Guyana). In this work, we considered the possibility of using microphytobenthos (MPB) as a biological indicator of the ecological status of estuaries. This activity report summarizes the actions undertaken in 2017 under an AFB / Université de Nantes convention, which is structured around two main axes: the first axis is based on the analysis of the... |
