Coupling GPR and ERT data interpretation to study the thermal imprint of a river in Syrdakh (Central Yakutia, Russia)
International audience The thermal influence of a river on the surface conditions of a continuous permafrost in Yedoma sediments of Central Yakutia (Siberia, Russia) is studied by active layer (AL) thickness measurements along a cross section, CS9, with direct AL measurements (e.g. drilling), Ground...
