Abstract

Permafrost thaw is associated with impacts on climate, land surface and coastal and river bank structures. Pro-cesses such as thermokarst and thermo-erosion lead to ground subsidence, which can have drastic e˙ects on the topography. One of the main drivers of surface subsidence vulnerability is the sedimentological composition, including ground ice content, and the temperature state of permafrost. This drilling campaign aimed to retrieve a deep, frozen sediment core from Samoylov Island to cover several scientific disciplines including geocryology, sedimentology and geochemistry. This campaign provides sample material from much greater depths (65.7 m) than previous boreholes on the island (27 m in 2006) and the anal-ysis of the sediments will therefore lead to a better understanding of the deep permafrost deposits on Samoylov Island. Furthermore, a temperature chain was installed in the borehole for long-term temperature monitoring.
