Abstract
The results of measurement of snow cover density for the period from 2005 to 2017. The data on snow density have been obtained during regular observations carried out on a stationary horizontal sites located in Yuzhno-Sakhalinsk and during field work. 227 snow pits have been sampled, and more than 2,000 values of snow density for different snow layers have been analyzed. Data on distribution of snow density in different landscapes have been compiled and structured. The maximum density of snow is typical for treeless regions with dominating strong winds. Typical densities for specific snow structure have been revealed. The density of snow layers have been found to vary depending on the type of snow in the range from 40 kg/m3 (newly fallen snow) up to 790 kg/m3 (ice crust).
