  • Preferential export of permafrost-derived organic matter as retrogressive thaw slumping intensifies

    Open AccessLisa Bröder, Kirsi Keskitalo et al.ARTICLEEnvironmental Research Letters2021

    Enhanced warming of the Northern high latitudes has intensified thermokarst processes throughout the permafrost zone. Retrogressive thaw slumps (RTS), where thaw-driven erosion caused by ground ice melt creates terrain disturbances extending over tens of hectares, represent particularly dynamic thermokarst features. Biogeochemical transformation of the mobilized substrate may release CO 2 to the atmosphere and impact downstream ecosystems, yet it…

  • Permafrost-derived dissolved organic matter composition varies across permafrost end-members in the western Canadian Arctic

    Open AccessErin MacDonald, Suzanne E Tank et al.ARTICLEEnvironmental Research Letters2021

    Organic matter, upon dissolution into the aqueous state as dissolved organic matter (DOM), can undergo mineralization by microbes. There has been increasing effort to characterize DOM released from thawing permafrost because it may perpetuate a permafrost carbon feedback. Permafrost-derived DOM often has a composition that can be highly susceptible to mineralization by microbes, but most studies to date that characterize permafrost-derived DOM ha…

  • Particulate dominance of organic carbon mobilization from thaw slumps on the Peel Plateau, NT

    Open AccessSarah Shakil, Suzanne E Tank et al.ARTICLEEnvironmental Research Letters2020

    Climate change is increasing the frequency and intensity of thermokarst, and accelerating the delivery of terrestrial organic material from previously sequestered sources to aquatic systems, where it is subject to further biochemical alteration. Rapid climate change in the glacially conditioned ice-rich and ice-marginal terrain of the Peel Plateau, western Canada, is accelerating thaw-driven mass wasting in the form of retrogressive thaw slumps, …

  • Watershed slope as a predictor of fluvial dissolved organic matter and nitrate concentrations across geographical space and catchment size in the Arctic

    Open AccessCraig T Connolly, M S Khosh et al.ARTICLEEnvironmental Research Letters2018

    Understanding linkages between river chemistry and biological production in arctic coastal waters requires improved estimates of riverine nutrient export. Here we present the results of a synthesis effort focusing on relationships between watershed slope and seasonal concentrations of river-borne dissolved organic carbon (DOC), dissolved organic nitrogen (DON), and nitrate ( ${{{\rm{NO}}}_{3}}^{-}$ ) around the pan-Arctic. Strong negative relatio…

  • Multi-decadal increases in dissolved organic carbon and alkalinity flux from the Mackenzie drainage basin to the Arctic Ocean

    Open AccessSuzanne E Tank, Robert G Striegl et al.ARTICLEEnvironmental Research Letters2016

    Riverine exports of organic and inorganic carbon (OC, IC) to oceans are intricately linked to processes occurring on land. Across high latitudes, thawing permafrost, alteration of hydrologic flow paths, and changes in vegetation may all affect this flux, with subsequent implications for regional and global carbon (C) budgets. Using a unique, multi-decadal dataset of continuous discharge coupled with water chemistry measurements for the Mackenzie …

  • Biomass offsets little or none of permafrost carbon release from soils, streams, and wildfire

    Open AccessBenjamin W Abbott, Jeremy B Jones et al.ARTICLEEnvironmental Research Letters2016

    As the permafrost region warms, its large organic carbon pool will be increasingly vulnerable to decomposition, combustion, and hydrologic export. Models predict that some portion of this release will be offset by increased production of Arctic and boreal biomass; however, the lack of robust estimates of net carbon balance increases the risk of further overshooting international emissions targets. Precise empirical or model-based assessments of t…

  • Coordination and Sustainability of River Observing Activities in the Arctic

    Open AccessJ W McClelland, Suzanne E Tank et al.ARTICLEARCTIC2015

    To understand and respond to changes in the world’s northern regions, we need a coordinated system of long-term Arctic observations. River networks naturally integrate across landscapes and link the terrestrial and ocean domains. Changes in river discharge reflect changes in the terrestrial water balance, whereas changes in water chemistry are linked to changes in biogeochemical processes and water flow paths. Sustained measurements of river wate…
