Abundance of the life stages of two Calanus species during POLARSTERN cruise ARK-IX/1b (PS24)

Abundances of the life stages of the Calanus species Calanus finmarchicusand Calanus hyperboreus were calculated in the Arctic Ocean during Polarstern cruise ARK-IX/1b. Samples were taken with the Multinet midi (Hydrobios, Kiel), which is equipped with nine nets (mesh size: 150 µm), and Bongo nets (Mesh size 200/300 µm)
