Lena River biogeochemistry captured by a 4.5-year high-frequency sampling program Open
The Siberian Arctic is warming rapidly, causing permafrost to thaw and altering the biogeochemistry of aquatic environments, with cascading effects on the coastal and shelf ecosystems of the Arctic Ocean. The Lena River, one of the largest…

Limnological assessment of 51 climate-sensitive permafrost-thaw lakes in Central Yakutia, Siberia Open
Climate is rapidly changing in northern regions, including Central Yakutia, a densely populated area in Siberia. Here, permafrost-thaw lakes in topographical depressions, named “alaas”, are widely distributed. Alaases and the residual lake…
Alkalinity generation from carbonate weathering in a silicate-dominated headwater catchment at Iskorasfjellet, northern Norway Open
The weathering rate of carbonate minerals is several orders of magnitude higher than for silicate minerals. Therefore, small amounts of carbonate minerals have the potential to control the dissolved weathering loads in silicate-dominated c…
Central and Eastern Siberian High Latitude Lake Hydrochemistry Open
We present a long-year data collection of freshwater chemistry from 590 high latitude lakes based on water sampling during our past expeditions in the Central and Eastern Siberian continuous permafrost regions. We compiled and standardised…

Tracing the footprint of permafrost carbon supply to the Canadian Beaufort Sea Open
The Canadian Beaufort Sea receives large quantities of sediment, organic carbon and nutrients from rapid coastal erosion and permafrost degradation. In addition, the Mackenzie River, the largest North American Arctic river, discharges grea…

Lena River surface water monitoring near the Samoylov Island Research Station Open
Current warming, shifting hydrological regimes and accelerated permafrost thaw in the catchment of the Arctic rivers will affect their water biogeochemistry. The Lena River is the second largest Arctic river and 71 % of its catchment is ch…

Temperature, electrical conductivity, DOC, CDOM, stable water isotopes and major ions of Lena River water from April 2018 to April 2019 Open
A number of studies expect an increase of carbon export by rivers to the Arctic Ocean due to rapidly changing climate in the ArcticOne possible reason for the increase of carbon export is thawing permafrost, which can lead to a mobilizatio…
Electrical Conductivity, DOC, CDOM, stable water isotopes and major ions of the ice core LD18-BH-8 samples near the Samoylov Island Research Station Open
Current warming, shifting hydrological regimes and accelerated permafrost thaw in the catchment of the Arctic rivers will affect their water biogeochemistry and the ice that covers the river for more than half of the year. The Lena River i…

Erosion of ice-rich permafrost coasts and the release of dissolved organic carbon into the Arctic Ocean Open
Ice-rich permafrost coasts in the Arctic are highly sensitive to climate warming and erode at a pace that exceeds the global average. Permafrost coasts deliver vast amounts of organic carbon into the nearshore zone of the Arctic Ocean. Num…

Contribution of permafrost degradation landforms to summer export of DOC from Yedoma-type Ice Complex Open
Thermo-erosional landforms (valleys, gullies) and \ntheir associated streams are the main connecting pathways \nbetween inland permafrost areas and rivers and \ncoasts. Surface and ground waters are routed along \nthese streams, which tran…
