Active: No
Country:Antarctica
Site:Deception Island
Site Description:Deception Island, is an active strato-volcano on South Shetland Archipelago of Antarctica (62° 55′ 0″ S, 60° 37′ 0″ W), is a cold region with harsh remote and hostile environmental conditions. The permafrost and active layer existence, and the cold climate conditions together with volcanic material with height water content inside made this region of the Earth a perfect site to study the active layer and permafrost evolution involved in the Circumpolar Active Layer South (CALM-S) and TSP programs.
CALM-Code:A16

The CALM-S site on Deception Islands comprised flat terrain with volcanic and pyroclastic fragments on the surfaces and was installed near “Crater Lake” at 112 m. a.s.l. during the summer of 2006 Antarctic campaign,  no evidences of geothermal anomalies or surface vegetation have in the “Crater Lake” CALM-S site.Geophysical techniques like electrical resistivity, acoustic propagation and mechanical measurements, estimate the active layer thickness and indicate that the permafrost layer is thin (Vieira et al., 2008; Ramos et al., 2010), varying between 3 m and 25 m thick, with mean active-layer thickness (ALT) of around 29,7±2 cm (multi annual mean value measured by probing at the end of the summer seasons, 2006 to 2014 in the crater lake CALM-S site).
