Long‐term changes in the ground thermal regime of an artificially drained thaw‐lake basin in the Russian European north
Abstract Long‐term (1982–1995) observations of the ground thermal regime of a drained thaw‐lake basin in the Pechora Lowlands of the Russian European north revealed a high spatial and temporal variability in the ground temperature response to artificial drainage. The thermal response was controlled...
