Abstract

Aims

- To detect and characterise extreme events in a coastal ecosystem by combining in situ high-frequency observations and high-resolution numerical simulations

-To describe the interannual variability of extreme events in a context of climate change 

-To quantify the links between extreme low salinity episodes and both large and local scale processes, using weather regimes, precipitations and river runoffs as proxies of hydro-climate forcing
