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 in central Yakutia traverse areas of ice-rich permafrost that is sensitive to temperature changes. This study examined the thermal state of permafrost in un...

Pipelines are critical infrastructure for Yakutia, transporting vital supplies to communities in this vast northern region.
