Abstract
We measured radiocesium (134Cs and 137Cs) in seawater from the western subarctic area of the North Pacific Ocean, Bering Sea, and Arctic Ocean in 2013 and 2014. Fukushima-derived 134Cs in surface seawater was observed in the western subarctic area and Bering Sea but not in the Arctic Ocean. Vertical profile of 134Cs in the Canada Basin of the Arctic Ocean implies that Fukushima-derived 134Cs intruded into the basin from the Bering Sea through subsurface (150m depth) in 2014.Entities:
