We mapped the occurrence of more than one million ice wedge polygons over a landscape of approximately 1,200 square kilometers, just south of Prudhoe Bay in northern Alaska,...

Thermokarst lagoons develop in permafrost lowlands along the ice-rich Arctic coast when thermokarst lakes or basins with bottom elevations at or below sea level are breached by...

The data publication contains supplementary data to the article "Supplementary Dataset to: The catastrophic thermokarst lake drainage events of 2018 in northwestern Alaska:...

Field investigations were performed in the central Lena Delta. In total, 25 sites were investigated. The sites were chosen to represent a variety of vegetation communities of...

This raster dataset, in Cloud Optimized GeoTIFF format (COG), provides information on land surface changes at the pan-arctic scale. Multispectral Landsat-5 TM, Landsat-7 ETM+,...

Data were analyzed to study the role of an winter ice cover for methane cycles of three different stages in the lake-lagoon-shelf transition in a region of rapidly thawing...

The Quaternary geology map was created for the Yana-Indigirka (eastern part) and Kolyma lowlands, tundra and partly forest-tundra zones. The map corresponds to the nomenclature...

We synthesized data on the circum-Arctic and sub-Arctic distribution and thickness of Yedoma for compiling a preliminary circum-polar Yedoma map. For compiling this map, we used...

This dataset contains methane and nitrous oxide dissolved gas concentration, dissolved methane carbon isotope, and ancillary hydrographic data from research cruises in the North...

The presented dataset contains chamber measurements of methane transport (mg CH₄ g dry plant mass-1 day-1) through individual aerenchymous peatland plants and the ancillary data...

This dataset contains fluxes of carbon dioxide and methane on an active flood plain in the Siberian Lena River Delta during the growing seasons 2014 and 2015 by means of the...

Methane (CH4) production, oxidation, and emission were studied in ponds of the permafrost-affected polygonal tundra in northeast Siberia. Summer CH4 fluxes were measured with...

CO2 and CH4 production in aerobic and anaerobic incubation in sediments samples from Muostakh Island (sample code MUO12), the Buor Khaya Peninsula (BK8), and Bol'shoy Lyakhovsky...

The effects of oxygen availability, freezing and thawing, temperature, and labile organic matter (OM) additions on greenhouse gas production were studied in northeast Siberian...

We present geochemical and hydrochemical information on individual permafrost and seawater samples from the Yukon Coast in the western Canadian Arctic used for an incubation...

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...

Arctic permafrost stores vast amounts of methane (CH4) in subsurface reservoirs. Thawing permafrost creates areas for this potent greenhouse gas to be released to the...

The SAR Surface Soil Moisture (SSM) product is derived from the ENVISAT ASAR sensor operating in Global Monitoring (GM) mode. The SAR SSM product is a weekly mean composite at 1...
