Dataset of a globally relevant stock of soil nitrogen in the Yedoma permafros...
This dataset merges nitrogen data from the Yedoma domain. It includes numerous fieldwork campaigns, which take place since 1998. In total 467 samples from the active layer... -
SAM18-01 Samoylov permafrost drilling, Lena Delta, NE Siberia
Using a new 65 m long sediment core from the Lena delta apex (Samoylov Island), NE Siberia, this project uses a range of sediment and ground ice properties to help... -
Permafrost-Region Lake-DOC version1 Database (PeRL-DOCv1)
The pan-Arctic Permafrost-Region Lake-DOC version1 database contains surface water samples of lakes in the permafrost regions of Alaska (49.3 %), Canada (24.2 %), Greenland (3.2... -
Stable water isotope composition and radiocarbon dates of permafrost ice wedg...
Seven profiles of permafrost ground ice (i.e. ice wedges) were sampled in 1999, 2007 and 2014 either by chainsaw or by ice screw at coastal bluffs east and west of the Zimov'e... -
Pollen profile of sediment core BK-8
Organic matter deposited in ancient, ice-rich permafrost sediments is vulnerable to climate change and may contribute to the future release of greenhouse gases; it is thus... -
Comprehensive snow, soil, water, and climate data from Qeqertarsuaq (Disko Is...
Permafrost regions play a critical role in the global climate system, as they contain significant stores of organic carbon, much of which has been preserved in permanently... -
Meteorological and soil data from Bayelva, Svalbard, homogenised data product...
Understanding permafrost processes and their links to polar climate requires long-term observational datasets. This data product is a quality-controlled and homogenised... -
Continuous measurements in soil and air at the permafrost long-term observato...
Understanding permafrost processes and changes requires long-term observational datasets of ground and climate variables. Despite the fact that the Arctic climate changes more... -
Soil data at station Bayelva in 2024 (level 1)
Understanding permafrost processes and changes requires long-term observational datasets. This dataset is a continuation of the dataset available from the Bayelva Site at... -

Spatial extent of Arctic river deltas
This geospatial layer (shapefile) provides the spatial extent of 211 river deltas in the Arctic and was established by digitizing Arctic deltas based on (very) high resolution... -
Characteristics of Arctic river deltas
The data set summarizes the input and output data for the study Large stocks of permafrost soil organic carbon and nitrogen in Arctic river deltas (Fuchs et al. in prep.). The... -
Carbon and nitrogen stocks for permafrost cores in the Noatak, Kobuk and Sela...
This data set describes the soil core and sample characteristics from soil cores collected in the Noatak (67.03 N; -162.45 E), Kobuk (66.79 N; -161.37 E), and Selawik (66.58 N;... -
