Abstract
The effectiveness of CO_2 injection in the sea off Japan was examined based on the calculation of the mean circulation in the Pacific Ocean. The diffusion calculation of CO_2 was carried out to predict the increasing of CO_2 concentration in the water body and to explore the effective CO_2 injection sea area near Japan, which suggests that CO_2 injection into the ocean abyss offshore of Japan on shifting the sea area by moving ship is more effective measure of CO_2 disposal than that of fixed sea area disposal.
