Study Site: Utikuma Region Study Area in northern Alberta
Purpose: Stream dissolved organic matter (DOM) provides a link between terrestrial and aquatic ecosystems and controls many aquatic
functions. Spatial and temporal variability of stream DOM differs amongst regions due to interactions between climate and phys
iogeography, and few studies have investigated stream DOM characteristics in the Boreal Plains ecozone in western Canada. The
Boreal Plains has a subhumid climate, flat terrain, widespread wetlands, sedimentary bedrock and thick heterogeneous glacial
deposits which cause complex surface water–groundwater interactions. To describe the spatial and temporal variability and main
controls on stream DOM in this region, we monitored dissolved organic carbon (DOC) concentrations and DOM composition
(assessed through UV–vis absorbance and fluorescence spectroscopy) in 17 streams with wetland- dominated catchments over
3 years (2018–2020).
Abstract: This dataset contains water chemistry data (major ions, inorganic nutrients, dissolved organic carbon, total dissolved nitrogen, in situ pH, conductivity and temperature) and dissolved organic matter composition data (absorbance and fluorescence) collected between 2018 and 2022 from 17 streams at the Utikuma Region Study Area (URSA) in northern Alberta, Canada
