Research Abstract

Analysis of sediment cores from the Toyama Deep-Sea Channel in the Japan Sea and from a submarine fan in the Nanakai Trough revealed that submarine fan development was controlled by climate changes in the time scale of ten to hundred thousands years whereas it was controlled by tectonics in the longer time scale of million years. It was also clarified that submarine fan development was associated with transportation of abundant organic carbon derived from terrestrial plants into sea floors, thereby stored atmospheric CO_2 in the submarine fan. This study clarified the hypothesis that submarine fan development acted as a buffer for global warming if rapid warming took place. Rapid warming would result in increase in precipitation, which in turn, leads to submarine fan development, thereby increase capacity for CO_2 storage.
