海洋における有機物現存量の定常性に関する研究

抄録

At each localized sphere for dynamics of organic matter in the sea, the total amount of nutrient substances is constant, and the total and inorganic substances must keep a steady state within a certain time.
Based on the simplified assumptions, the mechanism of this steady state in the sea was analyzed using the data of primary productivity, especialy nutrient absorption of diatom. When a certain amount of phosphate was supplied to different volume of a basic medium, the absorbed-phosphate per pigment unit (chlorophyll-αμg per liter) of diatom was constant. The absorbed-phosphate per pigment unit and initial concentration of phosphate in the medium had linear relationship within about 200μg phosphate per liter of the medium. The curves of experimental phosphate absorption and growth of diatom were found to be consistent with the theoretical one.
