This dataset contains four (4) electrical resistivity tomography (ERT) surveys taken during a summer 2023 Arctic expedition, led by the Alfred Wegener Institute Helmholtz Centre... -
Comprehensive snow, soil, and climate data from central Samoylov Island, Lena...
The Arctic is changing rapidly as strong air temperature warming induces a multitude of feedback mechanisms including changes in the snow cover and warming and thawing of... -
One year anaerobic incubation measurements (CH4+CO2) and microbe quantificati...
The data sets were made during the summer 2021, with samples collected from three cores, at two depths (active and permafrost layers). In total, six samples (3 replicates by... -
Carbon dioxide and and methane flux data, temperature and thaw depth from tha...
The dataset comprises in situ CO2 and CH4 fluxes, active layer depths, thawed carbon pools and soil temperatures from different non-vegetated soils in an active thaw slump in... -
Sedimentological, biogeochemical and hydrochemical characteristics of deep dr...
Current warming, sea-level rise, coastal erosion and accelerated permafrost thaw is leading to increasing thermokarst lagoon formation along wide parts of the arctic coast.... -
Automatic weather stations and stand-alone soil temperature sensors (Hobo log...
This data set includes meteorological and soil temperature data obtained from two study areas in Eastern Siberia. The first study area is located at Lake Illirney in Chukotka,... -
Erosion rates of the Sobo-Sise yedoma permafrost cliff in the Lena River Delt...
Permafrost thaw and ice wedge degradation lead to drastic landscape changes in the permafrost region. With this data set we investigated the cliff retreat of the Sobo-Sise Cliff... -
Water and sediment properties at Polar Fox Lagoon
As the Arctic coast erodes, it drains thermokarst lakes, transforming them into lagoons, and, eventually, integrates them into subsea permafrost. Lagoons represent the first... -
