Fig. 57. Charts showing the distribution of Calanus simillimns in the upper layers of water at stations in the 

 1926-7 surveys. The squares represent the average numbers per 50 m. vertical haul with N 70 V nets from 

 250 m. (or less at shallow-water stations) to the surface. For hydrological and phytoplankton conditions 

 see Figs. 2, 6, 7, 8, 38, 39 and 41.
