With the aim of evaluating factors which may influence the bacterial distribution in the sea of Hiuchi-Nada area, bacteriological and oceanographic surveys were conducted. By regression analysis the following equation was obtained from 98 sets of observations: log Y=0.104X1-0.515X2+0.003X4+2.745 where Y is the number of total bacteria, X1 is the temperature of water, X2 is the temperature difference between sample and surface water, X4 is the ultraviolet absorption value of water at 270 mμ. The multiple coefficient of determination adjusted for the degree of freedom was 77.7%. It seems reasonable to assume that only 3 variables, X1, X2 and X4, were mainly involved in the seasonal, vertical and geographic distributions of total bacteria in the waters.
