Table 191. Quantity of plankton in the Black Sea, summer 1939 (S. Maljatzky) 



M. Dobrzanskaya (1954) gives the comparative data on phytoplankton 

 production, obtained from photosynthesis data for the different Seas {Table 

 192). It follows from them that (7) the Black Sea in this respect is not inferior

 in phytoplankton as the deeper waters.
