We first identified all the zooplankton per large taxonomic groups (typically Order), and later several taxonomic experts helped us to identify species for the 12 selected zooplankton groups: Copepoda, Cladocera, Decapoda, Euphausiacea, Amphipoda, Mysidacea, Siphonophora, Chaetognatha, Pteropoda, Appendicularia, Cephalopoda, and Pisces (fish larvae).
