Keywords:Fukushima Daiichi Nuclear Power Plant accident, 137Cs, Intercomparison simulation, Ocean general circulation model

We carried out oceanic dispersion simulations on the Fukushima-derived 137Cs. Five kinds of oceanographical data calculated with data assimilation were used for the oceanic dispersion simulations in order to analyze the 137Cs dispersion and amount in the coastal area and the North Pacific.
