Seasonal and Spatial Variability of Dissolved Carbon Concentration and Composition in Lake Michigan Tributaries

Abstract: Dissolved forms of carbon represent a significant portion of the global carbon pool (Cole et al., 2007). Dissolved inorganic carbon (DIC) exists as carbonate species in water and is the major contributor to alkalinity in most natural waters (Stumm & Morgan, 1996), although it is important to note non-carbonate species can contribute to alkalinity in some cases (Golub et al., 2017;Hunt et al., 2011). DIC exchanges with carbon dioxide in the atmosphere and can be converted to and from dissolved organic matter (D… Show more

“…The 48 samples span the range of DOM types in freshwater systems (Table S1) and vary widely in water chemistry (Figures S1–S11; Tables S2–S4). Natural water samples are categorized into five groups (e.g., St. Louis River (SLR), Northern Lakes, Yahara, Mankato, or Twin Cities) based on their geographical location because land cover influences DOM composition . Wastewater effluents are grouped separately.…”

“…Natural water samples are categorized into five groups (e.g., St. Louis River (SLR), Northern Lakes, Yahara, Mankato, or Twin Cities) based on their geographical location because land cover influences DOM composition. 56 Wastewater effluents are grouped separately. Elevated ion concentrations are observed in wastewater samples compared to natural waters.…”

“…O : C w ranges from 0.20 to 0.55 and is lower in urban samples than in other groups, which corresponds to more reduced DOM. Note that DOM composition can vary temporally and spatially within individual water bodies; 21,22,65,66 therefore, these samples represent DOM composition at the time of sample collection. Collectively, the bulk and molecular measurements demonstrate that the DOM composition in these samples spans the range expected in natural and engineered systems, making the results of this study applicable to many water systems.…”

“…For example, concentrations range from 1-3 mg C L −1 in oligotrophic systems to 10->35 mg C L −1 in rivers and wetlands. [19][20][21][22][23][24][25] The composition of DOM is determined by its source (e.g., terrestrial and/or microbial) and its extent of biological and photochemical processing. Importantly, the composition of DOM plays a major role in the formation of PPRI.…”

“…2,48 Yet, F D increased with increasing pH for these samples, whereas numerous prior studies have demonstrated positive correlations between F D and E2 : E3. 18,[49][50][51][52] This suggests that interpretation of F D relationship to DOM optical surrogates (e.g., E2 : E3) should be interpreted with caution across diverse sources of DOM in the absence of direct measurements of molecular size and chemical composition.…”
