This dataset includes subsurface temperature data from four different sample locations within the Tasiapik Valley, near the village of Umiujaq, Nunavik, Quebec, Canada. Each...

These data were collected near Kennady Lake Northwest Territories, Canada. Data comprise air and ground temperature and air humidity measurements and detailed metadata...

The Canadian Permafrost Electrical Resistivity Survey Database (CPERS) is a collection of electrical resistivity tomography (ERT) datasets collected in permafrost environments....

This dataset includes a compilation of ground temperature data for two different locations in Kugluk Regional Park, near the community of Kugluktuk (Nunavut, Canada). These...

This dataset presents a compilation of paleomagnetic records from glacigenic sedimentary sequences studied on Bylot Island (Nunavut). Discrete sediment samples were collected...

Long-term monitoring of lakes and fjords on the northern coast of Ellesmere Island, Nunavut, provides information on the effects of climate change on these ecosystems and their...

During the summers of 2016, 2017 and 2018, field campaigns were conducted to study ice wedges and changes in the landscape of the Narsajuaq River Valley. The data presented here...

Long-term monitoring of lakes and fjords on the northern coast of Ellesmere Island, Nunavut, provides information on the effects of climate change on these ecosystems and their...

Many vertebrate species in tundra communities occur in low abundance but may play an important role in terrestrial food webs. Although estimates of their absolute abundance may...

Arctic lakes and ponds can be hot spots for greenhouse gas (GHG) emissions, yet studies are scarce, particularly outside the peak summer season. Here we present GHG diffusive...

This dataset presents data on soil properties (volumetric ice content, organic matter content, grain size) that come from two thermo-erosion gullies that were studied in the...

This dataset presents thaw front depths (TFD) measurements made in two thermo-erosional gullies on Bylot Island, Nunavut, Canada, from probing to refusal with a graduated steel...

This database contains the spatial coordinates and years (timing and duration) of activity for more than 7400 retrogressive thaw slumps (RTS) in five areas of the western...

The coastal Labrador peatland permafrost borehole monitoring network is comprised of a series of shallow boreholes (up to 5.7 m) drilled in palsas and peat plateaus across...

Winter conditions profoundly alter the limnological properties of lotic ecosystems. In 2019, from February 25 to March 1, we sampled the under-ice water column of the Great...

In 2019, a thermokarst lake located in low-shrub polygonal tundra in the Old Crow Flats (Yukon, Canada) drained catastrophically, forming a 1.9km2 drained basin containing a...

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...

The chemical characteristics of lakes change according to local conditions in their watershed: soil type, vegetation type, proximity to the coast, etc. We studied 49 lakes...

Ponds were sampled every July on Bylot Island (Qarlikturvik Valley, 73°09’N, 79°58’W) from 2017 to 2019. In 2017 and 2018, ponds were sampled twice during the sampling campaign....

This data was used to evaluate links between limnological processes and climate in the article "Regime shifts in lake oxygen and temperature in the rapidly warming high Arctic"....
