Water migration and ice segregation in the transition zone between thawed and frozen soil

Samples of silty clay were kept under constant boundary temperature conditions of +1°C (top) and −1°C (bottom) in a series of cold room laboratory experiments. Water migration and ice enrichment near the permafrost table were observed in all samples. Cryogenic layering was observed in soil layers wi...
