Abstract


A new model for describing the behavior of the isotope (d18О, dD) parameters of desalinated seawater during freezing is proposed. The model was tested using the Laptev Sea shelf waters, which are actively desalinated by the Lena river input and modified by the freezing and ice removing. It is shown that taking into account the modification process leads to the correction of estimates of the fraction of fresh water input up to 20%. A criterion for determination of model availability is proposed.
