Author proposed the new method of gaseous CO2 dissolution in the ocean. The system is composed of the horizontal vessel installed in the proper depth of the sea and CO2 supplying and activating system of the interface of both fluids. Dense water in which CO2 molecules are dissolved will flow down toward the sea floor inducing the bulk flow in the ocean and being accompanied with the molecular diffusions. These phenomena were treated analytically in the turbulent field by means of the k-ε two-equation model, which was applied to the semi-infinitive domain in the ocean. The basic datum of CO2 mass transfer flux at the interface and density change of CO2 dissolved water were obtained by the experiments of various kinds of pressure tests and the eddy viscosity and eddy diffusion coefficients were derived from the above mentioned turbulent model. Analyses were carried out with the two-dimensional cylindrical coordinate system under the still water assumptions.
