Your fluxes of Cs to the ocean from both rivers and the FDNPP drop considerably in 2018 and 2019 relative to 2012-2017. What is the reason? I assume these values are per year? in which case the values 0.2-0.8 TBq/yr are similar to values of Cs input calculated from groundwater input associated with the beaches (Sanial et al., PNAS 2017).
Thank you very much for your comment. Fluxes of Cs to the ocean during 2012-2017 means total amount of discharge. I think I would like to compare the Cs fluxes from the river, 1F, and groundwater in the future.
