Extract

Thirteen cruises were made between mid-March and early June in 1954 off the coasts of southern Scotland and north-east England. It is likely that a Calanus patch was followed continuously during this period merely by observing the abundance of Calanus in and out the patch at very short time intervals (5–8 days between the mid-points of the cruises). Fig. 3 in Cushing & Tungate (1963) shows the distribution of Calanus copepoditestages during the period, which is the sort of picture expected if the same population were being sampled during the period. Application of the Joseph & Sendner (1958) equation suggested that the reduction of density due to diffusion was likely to be very low.
