The remote geothermal method application (based on a multiple NOAA(AVHRR) satellite survey) on the
North Karelia, the White Sea, the Kola Peninsula, and the Northern part of Archangelsk Oblast territory
revealed few intensive (up to 25 W/m2) local anomalies of convective heat flow. One of them is
Sosnovskaya Thermal anomaly located at the Northern part of Big Solovetskii Island. Terrestrial heat flow
inside that anomaly composes the significant part of the positive part of a surface energy budget. It was
suggested that it should cause the specific thermophilic vegetation at the Island. The tectonic interpretation
of Landsat ETM+ images was carried out to verify this hypothesis. As the result, the conclusion that the
Island was formed as volcano-plutonic structure is done. The analysis of lake surface temperature
(according day time Landsat ETM+ data) revealed few lakes with high surface temperature. Long time
ground truth activity, including temperature measurements of lake water, a water sampling for chemical
and phytoplankton analysis, the botanical investigations provided possibility to explain the thermophilic
vegetation of the Island by an additional endogenic heat discharge.
