Abstract.

The paper contains the results of active layer studies in Lorino monitoring site (Eastern Chukotka, Russia), conducted in framework of the Circumpolar Active Layer Monitoring (CALM) program during 2010-2015. The study site includes tundra landscapes of Eastern Chukotka coastal lowlands. The main purpose of the paper is to obtain spatial and temporal patterns of seasonal melting distribution and reveal the main natural factors defining active layer depth within study site. The author demonstrates the predominance of thermal forcing in active layer development, which was strongly complicated by local (microrelief, vegetation, soil moisture, etc.) conditions. These factors determined high spatial and temporal variability of active layer thickness within single grid (100×100 m). The study also reveals the lack of statistical data on natural characteristics and the need for further detailed studies of seasonal melting process.
