Monitoring the Permafrost Conditions along Pipeline Routes in Central Yakutia, Russia

Pipelines are critical infrastructure for Yakutia, transporting vital supplies to communities in this vast northern region. The pipeline routes central Yakutia traverse areas of ice-rich permafrost that is sensitive temperature changes. This study examined the thermal state undisturbed and disturbed settings along Lena River Mundulakh Reservoir water Mastakh Yakutsk gas considered effects climatic fluctuations surface disturbances (forest removal wildfire) over monitoring periods 28 18 years, respectively. geocryological conditions area, as well methods monitoring, described. observation results demonstrated significant increases mean annual ground upper layers, active-layer thickness following fire post-fire clearing. At some sites, progressive deepening active layer caused formation taliks reached top massive ice, initiating degradation. development extreme temperatures was analyzed according combination seasonal meteorological type anthropogenic impact. research can be extrapolated similar landscapes.
