Short summary
The high abundance of Trichodesmium and active nitrogen fixation in the Kuroshio were not explained by the nutrient (nitrate, phosphate, and iron) distribution. We observed a Trichodesmium bloom and high nitrogen fixation near islands situated along the Kuroshio. Numerical particle-tracking experiments simulated the transportation of water around the Ryukyu Islands to the Kuroshio. Our results indicate that Trichodesmium growing around the Ryukyu Islands could be advected into the Kuroshio.
