Permafrost and active layer monitoring in the maritime Antarctic: Preliminary
Abstract This paper describes results obtained from scientific work and experiments performed on Livingston and Deception Islands. Located in the South Shetland Archipelago, these islands have been some of the most sensitive regions over the last 50 years with respect to climate change with a Mean A...
