The Laboratory of Permafrost Geothermics conducts research to develop an understanding of spatial and temporal variations in the subsurface temperature distribution and permafrost within the geological structures and physiographic regions of northern Asia. Specific goals include:

  • collection, synthesis and analysis of geothermal data based on the geological-structural principle;
  • borehole temperature measurements;
  • determination of thermal and physical properties of soils and rocks; estimation of effective thermal conductivities of sedimentary complexes;
  • determination of the heat flux in different geological structures; estimation of the heat flow components;
  • improvement of measurement methods;
  • study of permafrost distribution and thickness within mineral and hydrocarbon deposits, geomorphological regions, and geological structures;
  • compilation of temperature databases;
  • development of a temperature monitoring network in northern Asia;
  • use of geothermal data for reconstruction of former permafrost and for prediction of future environmental changes;
  • study of heat flow redistribution related to topography and hydrocarbon occurrences;
  • evaluation of the current state of permafrost from analysis of heat flow in and below permafrost;
  • development and improvement of heat flow modeling methods;
  • evaluation of the factors controlling the ground temperature field.
