The dinoflagellate Alexandrium minutum is a toxic bloom-forming species that is distributed worldwide and frequently identified along the French coasts. It is important to define and understand the mechanisms that promote the formation of these blooms in order to assess the risks for ecosystem and human health. Most of previously published studies define the ecology of this species but usually focus on local and short-term scales. In this presentation, we examine A. minutum at broad temporal and spatial scales by using joint time-series of A. minutum and environmental parameters along the French coasts. The dataset used for the analysis is a long-term (1988-present) time series that combines environmental and phytoplankton variables from REPHY French monitoring program, satellite data (Irradiance) and climatic data (North Atlantic Oscillation index). We present the preliminary results obtained based on i) the definition of environmental ...
