Richards (1957) has suggested that the increase 

 in silicate relative to phosphorus in deep water 

 originates from in situ resolution of skeletal re- 

 mains of diatoms or from resolution of bottom 

 deposits followed by upward diffusion. 



Summary 



Low nutrient values and a limited range of con- 

 centrations from surface to bottom are found in the 

 Kane Basin. As Baffin Bay is approached the 



range of values increases and more distinct inter- 

 mediate-depth maxima occur. An excessive ac- 

 cumulation of nutrient salts in the deep water of 

 Baffin Bay is found. It is suggested that this rep- 

 resents at least partly a reservoir of excess nutri- 

 ents from Kane Basin and Smith Sound. The 

 organic phosphorus level suggests a considerable 

 biomass. Ratios of change (by atoms) between 

 the nutrient elements are not markedly different 

 from those in other areas.
