100 in Lies of the norch coast of the Canadian Arctic Archipelago. The samplir.g 

 site consisted of a hole through 14 feet of pack ice, about ?00 feet from the 

 edge of the island. The techniques used for measuring the primary products, vity 

 and the chlorophyll concentration were presented by Apollonio (1958) . The 

 samples were subsequently analyzed at the Woods Hole Oceanographic Institution, 

 The results of the primary productivity measurements are given in milligrams of 

 carbon assimilated per cubic meter per day rather than milligrams per cubic 

 meter per hour. Chlorophyll a ccncentration is given in milligrams per cubic 

 meter.

Primary productivity measurements have been effected by the Steemann Nielsen

 (1952) method and except that the dark uptake of C was corre;ted for but no 



correction was made for respiration. The chlorophyll a concentration was 



determined by the method of Richards with Thompson (1952) ^ and reported as 



milligrams per cubic meter. More information is available from Fuglister, X1957

Local Zone Time.

 of four transatlantic sections, in the North and South Atlantic. Primary 

 productivity results have been reported in milligrams of carbon assimilated 

 per cubic meter per hour. The scientific party included R. A. Luftburrow, 

 D. A. McGlll; N. Rosa. C. D. Densmore, J. L. Schilling and F. C, Fuglister,
