DT . Observations made on the Rcyal Research Ship DISCOVERY 11 ;, Captain 

 So So Fo Dalgliesh, under the scientific leadership of Ho F. P, Herdman. This 

 program was carried out jointly by staff members of the National Institute of 

 Oceanography, Wormley, and the Woods Hole Oceanographic Institution. The 

 Primary productivity is presented in grams of carbon assimilated p^"r square 

 meter per day and the chlorophyll a concentration was given in milligrams per 



cubic meter. Steemann Nielsen method was employed for thfe primary productivity 



14 

 measurements, (Steemann Nielsen, 1952) except that dark uptake of C was 



corrected for, but no correction was made for respiration. The chlorophyll a 



concentrations were analyzed according to the method of Richards with Thompson 



(1952) , More detailed information on the techniques used has been given by 



Fuglister, (1957 appendix A) .
