Fractionation in the surface waters follows a typical Rayleigh-type distillation curve for a ‘closed’ surface water reservoir resulting from stratification of the surface layer in the subarctic region. Webisotopic fractionation followed Rayleigh-type fractionation in such a way that lighter isotopes were preferentially reduced and removed from thevessel.
