Dataset for "Mineralization of organic matter in boreal lake sediments: Rates, pathways and nature of the fermenting substrates" Clayer et al.

This dataset includes porewater solute concentrations (CH4, DIC, Cl, NO3, SO4, Acetate, Fe, Mn, S(-II), Mg, Ca) and carbon isotopic signatures of CH4 and DIC in the sediment of three boreal lake basins (Lake Tantaré basin A and B, and Lake Bédard) in October 2014 or 2015, as well as for Lake Bédard in October 2003. Detailed information about the methodology can be found in Clayer et al. (2016 and 2018). The content of this resource serves as the data for \"Mineralization of organic matter in boreal lake sediments: Rates, pathways and nature of the fermenting substrates\" by Clayer et al. 2020, Biogeosciences
