Abstract: Succeeding to two previous reports, we tried to elucidate the relation between cell number and E670-value in this report. From a view point monthly, proportionality existed between them generally (Tab. 1) but in each case the relation was not always so, for the relation was differnt considerably in every sample (Fig. 1). Therefore, to analyse in detail. the authors showed figures (Fig. 2 & 3) of the relation between cell number and E670-value per one cell, in stead of E670-value, and knew that the relation was hyperbolic (Fig. 2), experimental equation being linear in logarithmic expression (Fig. 3). But circumstances are differ by cell number; i. e. in the case of cell number less than 300,000 cells per liter, the more cell number per liter we observe the less E₆₇₀-value per one cell we obtain. The experimental equation is log y₂=-0.9675logx+3.6258 where x is cell number per liter and y₂ is E₆₇₀-value per one cell, determined by the method already described in the previous reports. Consequently. it will be clear that the less cell number per liter we observe the more E₆₇₀-value per one cell we obtain; this is, minimum cell number agrees with maximum E₆₇₀-value per one cell. Therefore, in the coastal region, the authors guessed that during the plankton desert period or interval term of the two succeeding prosperities of population E₆₇₀-value per one cell becomes rather plentiful.
