 Fig. 16. Rate of assimilation by bacterioplankton (4°N, 135°W) of the 

 labeled protein hydrolysate injected into a sample of sea water at 

 moment of closing of a water bottle at 4000 m depth after its subsequent 

 exposure at this depth for 7 days (1), then in the laboratory at 2°C (2) 

 and on the deck at 30°C (3). Initial concentration of hydrolysate in 

 samples 0.3 mg/1 , initial radioactivity .2 10" pulses/1. R = 

 radioactivity of bacterioplankton, 10^ pulses/100 ml.
