Temporal variations in (a) total-137Cs concentrations on the sampling date, (b) 134Cs concentrations on the FDNPP accident date, (c) FD-137Cs concentrations on the sampling date, (d) FD-137Cs concentrations re-corrected to 2017, and (e) fractions of FD-137Cs in MR19–24 and OS23 waters in the Bering Sea and Alaskan Stream along with previous data11,20,32, compared with KH17. Two waters in 2020 have been tentatively classified as sct-sB, based on their salinity and sampling locations.
