Calculations of new production (NP) are made based on hydrochemical characteristics, recycling production (RP) is assessed on the basis of recycling of phosphorus and nitrogen. Photosynthesis, coupling with uptake of nutrients and development of minimum of silicate and maximum of oxygen, at the lower chlorophyll maximum in the pycnocline is discussed. In situ determination of production by C-14 and oxygen and vertical scanning of chlorophyll A have permitted to calculate assimilation numbers for all the biohydrochemical areas and to map primary production (PP) distribution in the Bering Sea. The total PP in the Bering Sea has been assessed as 6.4x10**8 t C/yr.
