Bulk density, carbon and nitrogen content in soil profiles from permafrost in subarctic Canada

This dataset consists of measurements of bulk density, carbon and nitrogen content in soil profiles from permafrost in subarctic Canada. Soil cores were sampled during early summer in 2013 and 2014. Soil cores were sampled from a peatland plateau and thawing features of the peatland plateau, and from an unburnt and burnt black spruce forest, and additional sites in Yukon and Northwest Territories.

Soil cores were cut and samples were analysed for bulk density, carbon and nitrogen content. Samples were freeze dried and weighted to calculate bulk density. Values of bulk density are expressed in grams of dry soil per cm3 of wet soil. For carbon and nitrogen content, a ground sample was weighted and combusted in a C and N analyser. Standards were analysed in each run and a batch specific calibration was used to calculate the carbon and nitrogen content of the samples. Values of carbon and nitrogen content are expressed as percentage of dry soil mass.
