The AMORE-II research focused on establishing quantitative and qualitative links between nutrient enrichment, spreading of high-biomass algal blooms (Phaeocystis globosa but also the co-occurrent diatom Guinardia delicatula), presence of gelatinous zooplankton (the dinoflagellate Noctiluca Scintillans, the appendicularian Oïkoploira dioica) and impact on ecosystem function.
