    Numerical experiment for strontium-90 and cesium-137 in the Japan Sea

    A numerical experiment is carried out to reproduce distribution of concentration of 90Sr and 137Cs, estimate their total amount and verify their source in the Japan Sea. Model results are in good agreement with o...

    Modeling of the branches of the Tsushima Warm Current in the Eastern Japan Sea

    The branches of the Tsushima Warm Current (TWC) are realistically reproduced using a three-dimensional ocean general circulation model (OGCM). Simulated structures of the First Branch and the Second Branch of ...

    Sequential forecasting of the surface and subsurface conditions in the Japan Sea

    This study estimates a realistic change of the Japan Sea by assimilating satellite measurements into an eddy-resolving circulation model. Suboptimal but feasible assimilation schemes of approximate filtering a...

    Formation rate of water masses in the Japan sea

    Water masses in the subsurface and the intermediate layer are actively formed due to strong winter convection in the Japan Sea. It is probable that some fraction of pollution is carried into the layer below th...

    Simulation of the oil spill processes in the Sea of Japan with regional ocean circulation model

    A simulation of the movement of spilled oil after the incident of the Russian tanker Nakhodka in the Sea of Japan, in January 1997, was performed by a particle tracking model incorporating advection by currents,...
