Despite advances made possible with new instrumentation, still little is known about the distribution of phytoplankton assemblages at the meso/submesoscale and at the diel scale. The work presented here aims at investigating phytoplankton functional groups at those scales, with a focus on their distribution and traits through time and space in different areas, and on the role of environmental factors in shaping these distribution patterns. For this purpose, a pulse-shape flow cytometer was used <i>in-situ</i> at high-frequency, either on-board vessels or at fixed sites, to sample ocean-to-coast gradients, and coastal areas. Besides estimating concentrations of the different functional groups, a relationship derived from cell scatter helped estimating the biomass represented b...
