| Abstract;The ocean sequestration of carbon dioxide, which is thought a promising measure to mitigate the global warming, can be classified mainly into the dissolution and the storage methods. The former method can be applied to the ocean shallower than 2000 m where carbon dioxide is lighter than ambient seawater, and the latter to the dented ocean floor deeper than 3500 m where carbon dioxide becomes heavier than seawater saturated with carbon dioxide. On the evaluation of these measures, the hydrate of carbon dioxide plays an important role, because carbon dioxide becomes hydrate in the ocean deeper than 500 m (North Pacific Ocean)-900 m (North Atlantic Ocean). The solubility of carbon dioxide, which shows a dual nature (solid and liquid solubilities) in the hydrate-forming region, two types of unique hydrate membrane strengths observed just below the dissociation temperature and in the saturated solution with carbon dioxide, and the rebuilding process at stressed condition greatly influence on the above two ocean sequestration methods.
