    Abstract

    Complexity of direct determination o£ production intensity obliges the investigators to use indirect methods.In this work the method of calculation is based on the estimate of winter biogenous matter accumulation decrease in the upper layer,comparatively with underlayer,in summer period.
    The calculation showed considerable interannual changeability of production intensity,having the indications of three-year cyclicity:production maxima were noted in 1979, 1982, 1985 and 1988.
    The sychronism of interannual course of the primary production values in various characteristic zones of the sea.
