  • Description: Sixteen years (2005-2020) of zooplankton monitoring in the Bay of Marseille (N-W Mediterranean Sea) are analyzed in relation to physical, meteorological, climatic and biotic data. Samples were collected every two weeks by a vertical haul (0-55 m) of a 200 µm plankton net. Different indices characterizing the mesozooplankton are compared: biomass dry weight of four size fractions between 200 and 2000 µm; abundances of the whole of the mesozooplankton and of 13 main taxonomic groups defined from plankton imagery; seasonal onset timing of each zooplankton group; and two other types of indices, the first characterized diversity based on abundance data; and the second derived from zooplankton size spectra shape. The multi-indices approach showed different dynamics and the indices were complementary to disentangle changes in zooplankton. While the biomass of the four mesozooplankton size
