1950-1953年潮岬沖におけるプランクトン沈澱量の変動

抄録

The settling volume of the net samples which were collected in the years 1950 to 1953 in the open sea south of Shionomisaki tip shows the maximum in spring and minimum in autumn.
The annual mean of settling volume is largest in the coastal area and decreases gradually toward 31°30'N. It increases again around 30°30'N and reaches its minimum at the Ocean Weather Station T(29°N, 135°E). This tendency of fluctuation seemed to be agreeably corre-sponding to the distributional pattern of the Kuroshio current and its counter current.
