Abundance of the life stages of two Calanus species during VALDIVIA cruise VAL136

Abundances of the life stages of the Calanus species Calanus finmarchicus and Calanus hyperboreus were calculated in the Arctic Ocean during Valdivia cruise VAL136. 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).
