Abundance of the life stages of three Calanus species and Metridia longa during Polarstern cruise ARK-XXVI/3 (PS78, TRANSARK)

Abundances of the life stages of the three Calanus species (Calanus finmarchicus, Calanus glacialis and Calanus hyperboreus) and Metridia longa was calculated in the Arctic Ocean during Polarstern cruise ARK-XXVI/3. Samples were taken with the Multinet maxi (Hydrobios, Kiel), which is equipped with nine nets (mesh size: 150 µm).
