Soil profile carbon 2008-2009

Soil organic carbon data from 6.9 cm diameter diamond-tipped coring (mineral soil) and 15x15 cm blocks (forest floor). For methods, see Ross et al. Forest Ecology and Management 489 (2021) 119049. Cores were attempted to be taken to either the depth of bedrock or 100 cm but the latter depth was not always reached. Sometimes the forest floor sample was found to contain A horizon (<200 g/kg carbon) and the carbon from this layer was subtracted from the forest floor and added to the mineral soil. Each site had six corings, when possible, and three forest floor blocks sampled at each of the six coring locations.
