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...
-
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...
