| Abstract | The Berre lagoon is one of the biggest Mediterranean lagoon. It is located in the South East of France. It’s a shallow semi-confined ecosystem (mean depth 6.5 m, depths greater than 8 m being restricted in the central and South parts). Its only connection to the Mediterranean Sea is the Caronte channel in the South West which allows tidal-driven water exchanges. The lagoon receives fresh water and nutrients from natural tributaries (Arc and Touloubre rivers) that drain high anthropised catchment basins. Moreover, a hydroelectric power plant became the main tributary of the lagoon since 1966: it discharged a mean of 3.3 x10ˆ9 m3 of fresh water per year (equivalent to 3.4 times the volume of the lagoon) and a mean of 525 000 tons of suspended matter per year, during the period 1966 – 1993. As a consequence, the Berre lagoon became particularly unstable, showing considerable salinity drop and variations (2 to 30) depending on seasonal electricity needs. Nutrients loads by both anthropised rivers and power plant led to frequent colored waters and development of macroalgae. Haline stratification favored anoxia and led to benthos disappearance. Changes were observed in Zostera sp. meadows too. |
