Zooplankton biomass from CPR records
Zooplankton biomass has been derived for all the zooplankton taxa counted in CPR samples. Dry weights were obtained for the main 173 zooplankton categories (108 species, 42 genera and 23 groups) multiplying the abundance of each taxon by the average dry weight per individual, which was obtained by direct measurements or calculated using dry weight taxa-specific weight-length regression equations.
Plankton taxa were assigned to the following trophic functional groups based on the information available from the literature:
| Plankton Taxa | Trophic Levels |
|---|---|
| Siphonophora | C |
| Polychaeta larvae | H,C |
| Cirripedae larvae | H |
| Mollusca Pteropoda | H |
| Bivalvia | H |
| Bryozoa | H |
| Ostracoda | C |
| Cladocera | H |
| Copepoda | H,C,O |
| Mysidacea | O |
| Cumacea | O |
| Isopoda | O |
| Amphipoda | C |
| Euphausiacea larvae, post-larvae | H, C |
| Sergestidae larvae | C |
| Decapoda larvae | C |
| Echinodermata | H |
| Chaetognata | C |
| Larvacea | O |
| Thaliacea | H |
C= Carnivorous; H= Herbivorous; O= omnivorous.
