Nitrogen is a nutrient that is often depleted in subtropical seas and is one of the primary factors controlling biological production. Various nitrogen supply processes have been announced to be important in the seas around Japan, but the contribution of each process to primary production has not been fully evaluated. In this research, we aim to elucidate how the various nitrogen supply processes contribute to the biological production in the seas around Japan by answering the following three questions for the Kuroshio Current and the adjacent subtropical gyre.
How much nitrogen is supplied to the surface waters of the Kuroshio via turbulence, nitrogen fixation, and atmospheric deposition?
How much nitrogen is transported by the Kuroshio Current to the western subtropical gyre?
How might future climate change affect each nitrogen supply process and nitrogen transport?
