Description

Natural 210Pb and artificial 137Cs were applied for estimation of sedimentation rates for 14 cores collected in the White Sea, Franz Victoria and Novaya Zemlya troughs. Vertical profiles of 137Cs with high resolution (0.5-1 cm) are presented for 18 cores. The agreement between sedimentation rates obtained from 210Pb age-dating and 137Cs vertical profiles was found. Two maxima of 137Cs specific activity were observed in the cores near the North Dvina and Onega mouths, which may be correspond to the Chernobyl accident and global fallouts in early 1960-s.
