The dispersal model is ASR's Pol3DD. The model is forced by hydrodynamic data from the HYCOM/NCODA system which provides on a weekly basis, daily oceanic current in the world ocean. The resolution in this part of the Pacific Ocean is around 8km x 8km cells. We are treating only the sea surface currents. Particles in the model are continuously released near the Fukushima Daiichi power plant since March 11th. The dispersal model keeps a trace of their visits in the model cells. The results here are expressed in number of visit per surface area of material which has been in contact at least once with the highly concentrated radioactive water.
