Water-soluble salts in the syngenetic ice wedges of Late-Pleistocene yedoma and in the modern ices and the water reservoirs from Ayon Island

Composition and content of water-soluble salts in the syngenetic ice wedges of the 25–30-m Late-Pleistocene yedoma and in the modern ices and the water reservoirs of Ayon Island. Analysis of major ion chemistry of ice - titration methods (titrimetric methods) are based on determining the quantity of a reagent of known concentration that is required to react completely with the analyte.
