Research Abstract

:In order to clarify how the nitrogen and carbon cycles in the ocean change spatiotemporally, we carried out the developments of the new estimations about these changes with a new sampling system. Applying the new estimations with the new sampling system to ocean observation, we had significant distributions of spatiotemporal distributions of nitrogen and carbon parameters in the North Pacific and the global ocean, indicating a possibility that we can obtain the detailed spatiotemporal distributions of change in ocean biogeochemical cycles.
