Rising air temperatures, intensifying wildfire activity, and human disturbance are driving
rapid permafrost thaw across the subarctic, particularly for thaw-sensitive discontinuous …

The riverine export fluxes of dissolved carbon, nutrient and metals from the land to the Arctic
Ocean are fairly well quantified for five large Arctic rivers but remain virtually unknown for …

Climate change and permafrost thaw may impact the mobilization of terrestrial dissolved
organic carbon (DOC), mercury (Hg), and neurotoxic methylmercury (MeHg) into aquatic …

Lakes in discontinuous permafrost peatlands are on the front lines of climate change,
sensitive to even modest increases in air temperature. The aim of this study was to provide …

Carbon emission from Arctic rivers constitutes a positive feedback between the climate
warming and C cycle. However, in case of rivers with extensive floodplains, the impacts of …

Despite the importance of small and medium size rivers of Siberian boreal zone in
greenhouse gases (GHG) emission, major knowledge gaps exist regarding its temporal …

Boreal catchments are composed of different land covers, such as forests, peatlands and
lakes, which differ in their runoff response to rainfall events. Understanding the individual …

Mobilization of dissolved organic carbon (DOC) and CO2 from the frozen peat to surface
waters in the permafrost zone of high latitude regions is expected to enhance under on …

Abstract The Hudson Plains, Canada, is one of the largest, undisturbed peatland regions
(370,000 km2) in the world. Air temperature in the Hudson Plains is increasing rapidly …

Ongoing permafrost thaw in northern peatland catchments may increase the production and
downstream delivery of neurotoxic methylmercury (MeHg) across the terrestrial-aquatic …
