    Techniques Used: Tomography, Transformation Assay

    a , summer (BH1) and b , winter (BH6) cores. In the winter core, the surface frost layer was ~50 cm thick, and the top of permafrost was observed at 700 cm belowground. Error bars for CH 4 and CO 2 concentrations and their δ 13 C values are the standard deviation (SD) of two technical replicates. Data for mcrA and pmoA absolute gene expression are presented as mean ± SEM of three technical replicates. Source data are provided as a Source Data file.
