CO2 and CH4 Production in Soil Incubations from Low and High Centered Polygons, Barrow, Alaska, 2012-2013

Roy Chowdhury, Taniya ; Graham, David; Wullschleger, Stan

The dataset consists of respiration and methane production rates obtained from soil microcosm studies carried out under controlled temperature and incubation conditions. Soils represent the low- and high-centered polygon active layers and permafrost (when present) from the NGEE-Arctic Intensive Study Site 1.

The data file contains the results of the incubation study for six cores: NGADG0017, NGADG0073, NGADG0005, NGADG0009, NGADG0048, NGADG0043. Core and soil characteristics are provided along with the incubation conditions, replicates, and CO2 and CH4 results.
