V. Data from the University of British Columbia, Lack of complete 

 location data has prevented our inclusion of nearly 500 values from the f orf 

 "Indian Arm" near Vancouver^ B. C. 



Wo Data from the University of Washington, Department of Oceanography, 

 provided through the courtesy of G, G. Anderson. The vessels used were the 

 BROWN BEAR (data groups coded W168-W280 ) and the ASTOR (data groups coded 

 W001-W004 ) operated at the dates and in the areas by the individuals listed 

 below. A wide variety of physical, chemical and some other biological data 

 were gathered on these cruises. 



According to G. C. Anderson (Personnel Communication) a Steemann-Nielsen 

 type incubator incorporating a revolving wheel was used. Bottles were exposed 

 to a 800 foot candlesfillumination by fluorescent lighting in a water bath. 

 Cruises up to W271 utilized 250 ml pyrex s'ample bottles, but beginning with 

 W275, 25 ml bottles were used. The in situ studijes listed for W275 and W280 

 were made in a deck incubator with Wratten neutral density filters, other- 

 wise in situ studies referred to the hanging of bottles back at the depth 

 from which the water vras collected. Before cruise W280, HA-grade millipore 

 filters were used for both the pigment and radiocarbon productivity measure- 

 ment filtratlons. Beginning with W280, however, PH-grade millipore filters 

 (0.3|a pores) have been used for the productivity filtrations. All data have 

 been corrected for variation in the inorganic carbon content of the sea vrater 

 and a 5 percent isotope effect has been accounted for. Before June, 1961, 

 the chlorophyll-a values for transmittance in the samples were read at 6f>0 m|i 

 rather than 665 rajj. as it is now; thus, the results of the modification ot the 

 Richards and Thompson (1952) technique used are minimal until July 1961. 

 Note that "total pigment" Includes non-astacine carotenoid in the case of 

 University of Washington data.
