Egg and pellet production of Calanus finmarchicus was measured at 6-h intervals at all stations during the second leg of the cruise. Calanus was collected at the surface 150-m using a WP2 plankton net, and incubated in chl-max water for 24-h. Each 6 hours females were transferred to a new food solution and eggs and pellets were counted. In the end of the experiment, females were measured for prosome length. The purpose of the exercise was to calculate the minimum carbon consumption of Calanus, and how large proportion of ingestion is egested as fast sinking fecal pellets, and when.
