Abstract

Abstract: [1] In the northwestern Pacific marginal seas, there has been a rapid temporal increase and spatial variability in the relative abundance of dissolved inorganic nitrogen over dissolved inorganic phosphate. The cause and mechanisms of this temporal and spatial variation is under debate. Recently, atmospheric deposition of nitrogen has been shown to be the major cause of the spatio‐temporal variation in the concentration ratio of dissolved nitrogen and phosphate. We show that the transport by ocean currents is a more crucial factor causing the spatio‐temporal variation in the ratio of dissolved nitrogen and phosphate in the study area. Key Points: Rapid increase of N abundance in the Northwestern Pacific Marginal Seas N budget considering the major current system was quantitatively calculated Ocean currents is crucial factor causing the variation in the N:P ratio
