PH0T04. Modified Fisher Gas Partitioner 



VJater samples x\rere frozen and returned to NAVOCEANO for reactive 

 phosphorus and reactive silicate analyses. The methods of Murphy 

 and Riley (1962) and Strickland and Parsons (1965) were used for 

 these analyses. 



Bathythermograph lowerings were taken by ship's personnel using 

 a mechanical BT. 



Plankton samples were taken while drifting on station and were 

 preserved in an aqueous solution of formaldehyde and returned to Dr. 

 N. Anderson of NAVOCEANO. 



The continuous air sampling program consisted of mounting a pump 

 on the flying bridge and drawing air through a filter. The filter 

 was changed every 3 days and stored for return to Dr. J. H. Harley 

 of the Health and Safety Laboratory, U.S. Atomic Energy Commission. 



Nannoplankton samples were collected for Dr. A. Mclntyre of the 

 Lament Geological Observatory for electronic microscopic analysis. 

 Surface water samples initially were sieved through a wire mesh to 

 remove all coarse material and then were pumped through a very fine 

 filter. The filters were stored and at the end of the survey forwarded 

 to Lamont Geological Observatory for analysis.
