Abstract Active layer increase may contribute to greenhouse gas emissions, ecosystem change, and increased hazards. Here, we show the results of field measurements of active-layer thickness from 156 monitoring sites in Arctic, Antarctic and mountain permafrost regions. Active layer thickness increased significantly …

Abstract. While permafrost is considered a permanently frozen soil, it often demonstrates evidence for internal processes, including fluid migration. Here, we present data of the chemical composition, Ra, Th, and Ac isotopes of saline permafrost from three closely-retrieved cores drilled at Adventdalen, …

The archipelago of Svalbard, at 76-80oN, is located at the heart of the continuous permafrost zone, which means that all exposed areas (glacier-free) are covered by 100-400m thick permafrost. Permafrost in valleys is often saline due to Early Holocene seawater ingression, followed …

Interferometric Synthetic Aperture Radar (InSAR) remote sensing of surface displacement in permafrost environments has the potential to resolve ground ice dynamics and potentially active layer thickness, yet field validation is sparse. Here we present a comparison between in-situ ground ice contents and …

ABSTRACT Ground ice, cryostratigraphical and sediment analyses have been done on samples from 16 boreholes covering the different landforms in the lower part of the valley Longyeardalen, where the largest settlement in Svalbard, Longyearbyen, is located. This allows the production of the …
