Short summary
We elucidated ocean dynamic processes causing spatially-heterogeneous sedimentary radiocaesium-137 distribution in and around the shelf off Fukushima and adjacent prefectures on the basis of numerical simulation. Our result suggests that accumulation of sedimentary radiocaesium-137 in a swath just offshore of shelf break results from spatiotemporal variation of bottom friction occurred via a periodic spring tide about every 2 weeks and via occasional strong wind.
