This dataset consists of soils dated using lead-210 (210Pb) in profiles from permafrost in subarctic Canada. Soil cores were sampled during early summer in 2013 and 2014 from peatland plateaus, thawing peatland plateaus, burnt and unburnt black spruce forests in Yukon and Northwest Territories. The upper part of the soil profile was dated using 210Pb to quantify recent carbon accumulation rates.
