A study on the steady state of total organic matter in the Ocean

Abstract

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 absorded-phosphate per pigment unit (chlorophyll-a μg 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 200 μg 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.
