Utilising a Suite of Isotopic and Elemental Tracers to Constrain Cryoturbation Rates and Patterns in a Non‐sorted Circle
The empirical quantification of rates of material movement in cryoturbated soils has lagged behind the physical and chemical characterisation of these materials. We applied a novel suite of elemental (C, Hg), stable isotope (13C) and radioisotope (137Cs, 210Pb, 14C, 10Be) tracers in conjunction with...

The empirical quantification of rates of material movement in cryoturbated soils has lagged behind the physical and chemical characterisation of these materials. We applied a novel suite of elemental (C, Hg), stable isotope (13C) and radioisotope (137Cs, 210Pb, 14C, 10Be) tracers in conjunction with analytical and numerical models to constrain the rates and patterns of soil movement due to cryoturbation in a non‐sorted circle (NSC) near Abisko, Sweden. We present the first observations of the variability of 10Be across a patterned‐ground feature, which facilitate the interpretation of subsurface peaks in soil organic carbon, Hg and 13C and provide constraints on the surficial histories of cryoturbated materials. Apparent rates of surficial lateral movement across the NSC estimated from 137Cs and 210Pb (0–2.55 cm year−1) decreased with distance from its centre and were an order of magnitude greater than rates of subduction and subsurface movement estimated from 14C (0.04–0.27 cm year−1).
