  • Catchment-scale thawing and greening decreases long-term nitrogen export in NE Greenland

    Open AccessShannon L Speir, Jennifer L Tank et al.ARTICLEEnvironmental Research Letters2024

    Climate change is expected to alter nitrogen (N) export from Arctic rivers, with potential implications for fragile coastal ecosystems and fisheries. Yet, the directionality of change is poorly understood, as increased mobilization of N in a ‘thawing’ Arctic is countered by higher rates of vegetative uptake in a ‘greening’ Arctic, particularly in the understudied region of Greenland. We use an unprecedented dataset of long-term ( n = 18 years) ri…

  • Uncertainty in streamflow measurements significantly impacts estimates of downstream nitrate export

    Open AccessShannon L Speir, C Nathan Jones et al.ARTICLEEnvironmental Research Letters2023

    Across watershed science, two key variables emerge–streamflow and solute concentration–which serve as the basis for efforts ranging from basic watershed biogeochemistry research to policy decisions surrounding watershed management. However, we rarely account for how error in discharge (Q) impacts estimates of downstream nutrient loading. Here, we examined the impact of uncertainty in streamflow measurements on estimates of downstream nitrate expo…
