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...

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...

Isotopic composition of ground ice, ebullition gases and thermokarst lake water, Alaska, 2008-2010
Thermokarst lakes are thought to have been an important source of methane (CH4) during the last deglaciation when atmospheric CH4 concentrations increased rapidly. Here we...
