| Outline of Final Research Achievements |
The aims of this study were to develop the high precise and simultaneous method for dissolved nitrogen and argon in the ocean, and to evaluate the oceanic amount of denitrification and nitrogen fixation by using the new approach. Using the above approaches, we found that the generation rate of dinitrification in the Sea of Okhotsk was over 7 micromole/kg/year despite no nitrogen fixation, and it significantly contributed to the oceanic nitrogen cycle in the North Pacific.
