In the Berre Lagoon (Marseille)
High frequency (hourly) monitoring of phytoplankton community in the largest brackish water lagoon in Mediterranean area was realized by means of a CytoSense by the researchers from MIO, Aix-Marseille University. Clusters revealed upon analysis of phytoplankton community were shown to be functional response groups, both regarding the daily variations as well as sudden environmental changes. The measurements showed dynamics of Akashiwo sanguinea throughout a strong wind episode (mistral). This species is known to form harmful algal blooms (HAB).
