Ecosystem model of a deep-sea plankton community for CO2 ocean sequestration

In order to conduct environmental assessments of CO₂ sequestration in deep-seas, the effects of high-concentration CO₂ on marine organisms is one of the most important factors prior to CO₂ sequestration practice. One-dimensional ecosystem model was developed to simulate the ecosystem in a deep-sea of more than 1,500 m depth, which corresponds to the dissolution depth for CO₂ ocean sequestration. Here we discuss the numerical results of CO₂ impacts on biological communities using the ecosystem model developed.
