We studied the influence of penguins on soil temperature and dynamics of active layer. Penguins have a marked role in changing active layer depth and thermal regime. The permafrost is important to control of physical reactions ground. The Freezing Degree Days, Thawing Degree Days and the N factor index were calculated.
