摘要：
The article gives the results of isotopic analysis of the composition of Karelian snow cover, which formed in winter of 2015/2016, and atmospheric precipitation in Petrozavodsk. It is shown that snow composition varies from -15.7 to -21.1 parts per thousand for delta O-18 and from -118 to -158 parts per thousand for delta H-2, and the isotopic composition becomes lighter in the direction from south to north in accordance with air temperature drop. The isotopic composition of winter precipitation can be approximately reconstructed by the isotopic composition of snow cover.
