Permafrost thaw incubation of soils from three Alaskan sites

The goal of this study was to understand how permafrost thaw impacts the microbiome and its contribution to carbon dioxide flux, using microcosm experiments with samples from three sites in Alaska. The sites are as follows: above the CRREL permafrost tunnel near Fairbanks, AK, the CRREL Farmer's Loop research site also near Fairbanks, AK , and the Barrow Experimental Observatory (BEO) in Utqiagvik, AK. We performed a 96-day thaw microcosm experiment at 2C with subsamples of permafrost. Data includes both in situ and post-thaw community compositions.
