As peatlands undergo extraction, their hydrological regime is altered by the creation of drainage channels leading to shifts in the carbon dynamics. The objective of this research is to examine how the changes in peatland hydrology affect transportation of DOC in an actively extracted peatland nested within a larger intact peatland, located in Eastern Quebec. Therefore, our aim is to track the movement of DOC as it is transported through the drainage channels and attempt to identify contributions of DOC from natural and extracted peatland sites. Through determining the SUVA of our DOC samples, we can assess the aromaticity of mobilized DOC. Hydrological monitoring and water sampling were both taken continuously and periodically from May 2022 to July 2023 at multiple locations to assess the spatial and temporal variabilities of DOC. The various sample types included: soil moisture water, precipitation, groundwater, and stream water. Filtering and analysis of DOC concentrations is complete, in all samples. The SUVA data is currently being assessed and will be used to identify the origins of the DOC and water entering the drainage channels. We anticipate the aromaticity of the DOC present in the field ditches will be primarily influenced by the extracted portion of the peatlands and as such, will show a corresponding aromaticity. Consequently, this would insinuate that majority of DOC present in the ditches is originating from the extracted sites. This research will aid in our understanding of the movement of DOC through an extracted system and the overall cycling of carbon.
