Outline of Final Research Achievements

By performing the Russian vessel Multanovsky Expedition in the Russian economic zone in June 2014, we succeeded in time-series observations of long-range current moorings and a glider with a turbulence profiler in and around the Kuril Straits and physical-chemical integrated observations on the Pacific side. Observed enhanced turbulence in the Bussol’ Strait leads to the discovery that thickness and iron/nutrient changes of outflowing Okhotsk Sea water through the strait to influence largely on the water-mass structures and ecosystem in the North Pacific. The enhanced turbulence is found to be generated by 1) the superposition of tidal and mean currents in the deep Bussol’ Strait and by 2) the enhanced down-slope currents accompanied by topographically-trapped waves in the shallow Urup Strait.
