Abstract

The seabed soil was collected at the Soya Strait of Hokkaido in September 2015, and ¹³⁴Cs derived from Fukushima Daiichi Nuclear Power Plant accident was detected at the seabed soil. It was suggested that this ¹³⁴Cs migrated from the Japan Sea to the Okhotsk Sea by the Tsushima Warm Current and the Soya Warm Current.
