Outline of Final Research Achievements

A new concept “Microbial Carbon Pump” as a mechanism which atmospheric carbon dioxide could be fixed into the ocean was examined by investigating distributions of refractory dissolved organic matter (DOM) and bacterial community in the Pacific Ocean, and using an incubation experiment on board. Consequently, it was evident that DOM poorly available for microbial utilization, which was enriched with carbon, accumulated in surface waters of subtropical areas. The distribution of terrigenous refractory DOM indicating by dissolved lignin, showed a clear peak in the North Pacific Intermediate Water (NPIW), suggesting that terrigenous DOM derived from rivers in the Eurasian Continent would be transported by NPIW and spread over the whole of the North Pacific.
