Michio Aoyama (Fukushima University) et al. (pdf), European Geosciences Union General Assembly, Apr 2015 (emphasis added): The oceanic distribution of Cs-137 and Cs-134 released from [Fukushima Daiichi] were investigated… During the period from end of March to early of April 2011, extremely high activities of Cs-137 and Cs-134 in seawater were concentrated along the coast… The high activities area spread to the region of 165_E with a latitudinal center of 40_N in the western North Pacific Ocean. Atmospheric deposition is also cause to high activities in the region between 180º and 130º W in the North Pacific Ocean. The total inventory of FNPP1-released Cs-134 in the North Pacific Ocean is estimated to be 15.2 +/- 1.8 PBq… Leak of stagnant water induced by heavy rainfall would also cause the increase of the total…
