| A study of the environmental factors in the "pertuis charentais" (charentais straits) has been carried out from 1993 tc 1994. The evolution of water temperature and salinity, as weil as the turbidity, are studied. ln the middle of Breton Strait, near to the long lines, the stratification has not been observed, and the salinity variations are much less sharp than in the stations which are located nearer the coast. The photosynthetic pigments concentrations can be very different in the same time at two close stations; in the Antioch Strait and at the long lines, the values of chlorophyll "a" are comparable; they are much higher in the Breton Strait. At the same time, a study has been made on the physical factors, the photosynthetic pigments concentrations,... |

| In the context of WFD implementation on Mediterranean lagoons, work has been carried out since 2010 by Ifremer, Tour du Valat and IRSTEA (Onema and AERM & C fundings), to assess the relevance of macrophytes and macrofauna indicators for oligohaline and mesohaline lagoons (mean salinity <18 PSU). The question of the relevance of indicator metrics and thresholds for the "phytoplankton" biological quality element also arises, especially due to the confined nature of olgo-mesohaline lagoons. The objective of this study is to characterize the abundance and composition of phytoplankton on 5 oligo and mesohaline lagoons of the French Mediterranean coast (Scamandre, Crey, Charnier, Bolmon and Grand Palun). Analyses of accessory pigments (chlorophyll and... |
