  abstract = {{P}lankton represents the main source of carbon in marine ecosystems and is consequently an important gateway for contaminants into the marine food webs. {D}uring the {MERITE}- {HIPPOCAMPE} campaign in the {M}editerranean {S}ea ({A}pril-{M}ay 2019), plankton was sampled from pumping and net tows at 10 stations from the {F}rench coast to the {G}ulf of {G}abe`s ({T}unisia) to obtain different size fractions in contrasted regions. {T}his study combines various approaches, including biochemical analyses, analyses of stable isotope ratios (813{C}, 815{N}), cytometry analyses and mixing models ({M}ix{S}iar) on size-fractions of phyto-and zooplankton from 0.7 to >2000 mu m. {P}ico-and nanoplankton represented a large energetic resource at the base of pelagic food webs. {P}roteins, lipids, and stable isotope ratios increased with size in zooplankton and were higher than in phytoplankton. {S}table isotope ratios suggest different sources of carbon and nutrients at the base of the planktonic food webs depending on the coast and the offshore area. {I}n addition, a link between productivity and trophic pathways was shown, with high trophic levels and low zooplankton biomass recorded in the offshore area. {T}he results of our study highlight spatial variations of the trophic structure within the plankton size-fractions and will contribute to assess the role of the plankton as a biological pump of contaminants.},
