Research Abstract

In order to clarify the long-term climate change in the North Pacific, we carried out the comprehensive ocean observations with physical-biological-chemical systems. Based on these observations, we had significant quantifications of ocean biogeochmical cycles with the parameterizations of greenhouse gases in this region. In addition, we could reconstruct the long-term climate change in this region by using improved ocean circulation models.
