Carbon Dioxide Production In Bedrock

Dataset required to replicate analysis in the manuscript "Carbon Dioxide Production in Bedrock beneath Soils Substantially Contributes to Forest Carbon Cycling". Here we provide (1) subsurface carbon dioxide and oxygen concentrations for the study duration collected from a bedrock vadose zone, (2) subsurface temperature for the dates of sampling, (3) relative rock moisture for the dates of analysis, (4) calculated diffusion coefficients used to calculate carbon dioxide flux from the weathered bedrock and (4) soil efflux measurements. Measurements are made at discrete intervals throughout a bedrock vadose zone using a Vadose Zone monitoring System (VMS). The bedrock of the study site is a marine turbidite that is part of the Coastal Belt of the Franciscan Complex. The study site is characterized by a steep hillslope, a Mediterranean climate that is seasonally dry, and a mixed canopy forest.
