Part of the carbon dioxide dissolved from the atmosphere into the sea is taken into phytoplankton, which settle to deposit on the deep-sea floor, and some is also carried and diffused by the surface and deep water currents. The Mutsu Institute for Oceanography conducts research to clarify the mechanism of material cycles in the Northwest Pacific Ocean, the area believed to be a major absorption source of carbon dioxide.
