Isotope composition of snow from individual snowfall in the northeast of Europe, December 2003

Isotope composition of snow samples from individual snowfall was measured on the transect of approximately 1400 km through the northeast of Europe from Konosha station through Inta Town and Seida Town up to Polar Ural. Stable isotope contents of Oxygen-18 and Deuterium as well as Deuterium excess are not constant in uniform air mass, but strongly vary depending on condensation temperature. It is demonstrated that the values of Oxygen-18 and deuterium decrease by 1.4 and 10.8 ‰ per 1 degree of latitude. With decreasing Oxygen-18 content by 8.17 ‰ and Deuterium by 60.3 ‰, Deuterium excess increases by 8.1 ‰. Data was collected inthe northeast of Europe between December 23rd and 24th 2003.
