文摘

The soil thermal regime is characteristic of polar desert affected by Dry-permafrost. Variations in soil temperature are intense during the summer, showing the response to radiation. The periglacial landforms, are not in phase with the present polar cold desert climate. The landscape dynamics evolves under scarce conditions that last for very short times. The thermal regime at Ellsworth is comparable to other continental areas such as the dry-valleys.
