    Dear Kumamoto,
    thank you so much for your poster and for all the work behind it.
    How much of the released 137Cs (and 134Cs) has been estimated to enter the Arctic Ocean?
    Thank you and all the best,

      Dear Nuria,

      Thank you for your interest.

      I have not estimated yet. But I think that the intrusion to the Arctic Ocean through the Bering Strait is limited because the Fukushima-derived 134Cs has been observed only in the Chukchi Sea where the Bering Strait forms its southernmost limit. As you know, in the Arctic Ocean, there is a large amount of 137Cs derived from the nuclear reprocessing plants in UK and France. Thus, it is hard to estimate the inventory of the Fukushima-derived 137Cs in the Arctic Ocean.

      Thank you.
