The Fisheries Agency of Japan is undertaking a man-made sea mount enterprise in order to increase the fishing resources in offshore area. It is thought that this enterprise leads to fixation of carbon dioxide by photosynthesis of phytoplankton. However, any detail evaluation has not been made on this subject.
Based on the carbon cycle published in the International Panel on Climate Change report on 2007, this paper considered the possibility of carbon dioxide fixation by the man-made sea mount. It was concluded that the man-made sea mount could contribute to sequestrate carbon dioxide by delivering from surface to deep sea.
