Dissolved methane and hydrochemical parameters in ice cores from 2017, Bykovsky Peninsula, Lena Delta
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... -
Database of Ice-Rich Yedoma Permafrost (IRYP)
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... -
Eddy covariance carbon fluxes and ancillary data, Samoylov Island, Lena River Delta, 2014-2015
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 fluxes, soil gas profiles and microbial activities in ponds at Samoylov, 2002 & 2013
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... -
Soil incubation data from ice-rich permafrost deposits in Northeast Siberia, 2014
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... -
Soil and incubation data of permafrost-affected soils in Samoylov, 2011 & 2013
The effects of oxygen availability, freezing and thawing, temperature, and labile organic matter (OM) additions on greenhouse gas production were studied in northeast Siberian... -
Geochemistry of incubated permafrost and seawater from the western Canadian Arctic
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... -
Anaerobic incubation measurements (CH4+CO2) and microbe quantification, Lena Delta, 2018
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... -
UAV-based methane data from Barter Island, September 2017, Barrow, 1986-2017, Alaska (US)
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... -
Inorganic and organic hydrochemistry of lakes and ponds in continuous permafrost landscapes in the western Canadian A...
Between 2006 and 2015 inorganic and organic hydrochemical parameters and stable water isotope characteristics were measured in lakes and ponds in continuous permafrost... -
Lake-DOC Database (PeRL-DOCv1), 1979-2017, Permafrost-Region
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... -
Database of Global Peatland Extent and Carbon Stocks through the Last Glacial Cycle (130 ka to present)
We present the first synthesis of global peatland extent through the last glacial cycle (130 ka) based on >975 detailed stratigraphic descriptions from exposures, soil pits,... -
Database of Ice-Rich Yedoma Permafrost Version 2 (IRYP v2)
Ice-rich permafrost in the circum-Arctic and sub-Arctic, such as late Pleistocene Yedoma, are especially prone to degradation due to climate change or human activity. When... -
Geochemical, lithological, and geochronological characteristics of sediment samples from Yedoma and thermokarst depos...
This dataset merges data from the yedoma domain in Northern Siberia (RU) and Alaska (US). It includes numerous fieldwork campaigns, which take place since 1998 . In total 224... -
