Biodegradable dissolved organic carbon (BDOC) and associated physical and chemical measurements from a boreal first-order stream reach.

Nine riparian sites along a boreal first-order stream were sampled for the purposes of assessing the percentage of biodegradable dissolved organic carbon (bDOC) in soil, groundwater, streamwater and lake water across 8 occasions between July to October 2022. These sites were sampled to encompass the variation in riparian hydrogeomorphology present within boreal headwaters, and to investigate bDOC concentrations within a land to water continuum. All water samples and soil solutions from extractions were also analysed for dissolved organic carbon, dissolved nutrients and optical properties. All soils were analysed for bulk organic matter content, extracellular enzyme activity (total of 5 enzymes) and phospholipid fatty acid (PLFA) content.
This data was collected from the Stortjärnbäcken stream reach in the Krycklan Catchment Study within the Svartberget Research Station (64°14ʹN, 19°46ʹE, Vasterbottens lan, Sweden) in collaboration with the Swedish University of Agricultural Sciences (SLU).
