Data from a photochemical and biological degradation experiment carried out...
These data originate from a dissolved organic matter (DOM) degradation experiment carried out at Bylot Island (Qarlikturvik Valley, 73°09’N, 79°58’W), in the eastern Canadian... -
Measurements of thaw front depth, surface organic layer thickness, soil...
Between June 2017 and September 2022, fieldwork was conducted in Old Crow Flats, Yukon (Canada) to study thermokarst lake and drained basin dynamics and hydrological connections... -
Water chemistry and benthic pigments in the Lake Meretta wetlands, Resolute...
The Meretta wetlands are an extensive area of shallow lakes, ponds and streams that mostly drain into Meretta Lake, in the Resolute Bay area, on Cornwallis Island in the... -
Zooplankton abundance and biomass in Arctic lakes and ponds of Southern...
Arctic landscapes are characterized by the presence of many lakes and ponds that exhibit distinct physico-chemical and biological properties. Since 2018, we have been studying... -
Size and bathymetry of Greiner Lake and other large lakes in its watershed, Nunavut
Most of the world’s lakes are in the Arctic, yet very little is known about these aquatic environments. We present here the size and depth data for five large lakes in the... -
Vegetation cover in and near drained basins in Old Crow Flats, Yukon, Canada
From August 25 to September 1, 2022, fieldwork was conducted in Old Crow Flats, Yukon (Canada) to study thermokarst lake and drained basin dynamics. As part of this work,... -
Data from an experimental study to determine the impact of snow hardness on...
Lemmings are an essential link of the Arctic food web as they are the main prey of many predators inhabiting these regions. These small rodents exhibiting cyclic fluctuation of... -
Permafrost geochemistry and retrogressive thaw slump morphology (Peel...
In ice-rich hummocky terrains spanning broad swaths of the Canadian Arctic, accelerating permafrost thaw and terrain subsidence (thermokarst) are exposing materials that were... -
Northern Ellesmere Island ice shelf and ice tongue extents
The ice shelves along the northern coast of Ellesmere Island have been in a state of decline since at least the early 20th century. Available data derived from explorers'... -
Seasonal ice cover and catchment changes at northern thermokarst ponds in...
Thermokarst ponds and lakes are common features of Arctic and subarctic landscapes, developing in depressions that result from the thawing of ice-rich permafrost. Most of these... -
Carbon, nitrogen and water content of the active layer from sites across the...
It is presumed that significant quantities of carbon are stored in permafrost soils and that the thawing permafrost could substantially raise atmospheric carbon dioxide...
