Thermograms of lakes of Bolshoy Solovetsky Island
Cultural and historic ensemble of the Solovetsky Islands is listed by UNESCO as the World Heritage Site. The Solovetsky archipelago comprises six islands in the western part of the White Sea, covering 300 km2. Population of the biggest island, Bolshoi Solovetsky, is under 1000, and about 30000 touri...
