This dataset consists of soil dates determined using radiocarbon in profiles from permafrost in subarctic Canada. Depth-specific soil core samples were dated using radiocarbon. Soil cores were sampled during early summer in 2013 and 2014. Each year soil cores were sampled from a peatland plateau, thawing features of the peatland plateau, unburnt and burnt black spruce forests, and additional sites in Yukon and Northwest Territories.
