Moisture Content Measurements of Moss (Sphagnum spp.) Layers Using Recently Developed Sensors. Permafrost and Periglacial Processes
Sphagnum (spp.) is widely distributed in permafrost regions around the arctic and subarctic. The moisture content of the moss layer affects the thermal insulative capacity and preservation of permafrost. It also controls the growth and collapse history of palsas and other peat mounds, and is relevan...
