PHOS Soluble phosphate concen- 



tration expressed in mi- 

 crogram-atoms of phos- 

 phorus per kilogram of 

 sea water. Deniges (1920) 

 method as modified by 

 Truog and Meyer (1929). 



NIT Nitrite nitrogen concen- 



tration expressed as mi- 

 crogram-atoms of nitrogen 

 per kilogram of sea water. 

 Griess (1879) method as 

 modified by Ilosvay ( 1889). 



SIL Soluble silicate concentra- 



tion expressed as micro- 

 gram-atoms of silicon per 

 kilogram of sea water.
