| Outline of Final Research Achievements |
We carried out research cruises covering over the Pacific Ocean and examined the distribution of biogenic elements by means of newly developed high sensitivity methods which is one of the main factors controlling quantity and function of ecosystem services. We obtained maps of nutrients, dissolved organic phosphate, dissolved humic substances, pH, alkalinity, and other forms of biogenic elements. New ocean provinces of the Pacific Ocean are proposed based on the geography of biogenic elements. For parameters of carbonate system, we carried out database analysis and showed the interannual variability with proceeding of global warming and ocean acidification. Using the obtained data of biogenic elements and physical oceanographic parameters, we also make it possible to estimate various parameters on marine ecosystem services such as distribution of fisheries target species by means of generalized additive model.
