A thermal profile of coastal permafrost at Varandey, Russia
Soil temperature variation is one of the governing factors to the stability of soil masses in regions affected by permafrost. Understanding of the thermal profile is critical for planning, designing, constructing and maintaining infrastructures which are much needed to sustain industry and/or commun...
