The Torngat Mountains of northern Labrador are an Arctic cordilleran mountain range located at the southern limit of the Canadian Arctic. Sparse observations of periglacial...

These data were obtained in an ice-wedge polygonal site in the Canadian high Arctic, in Qarlikturvik valley on Bylot Island at 73.15°N. The site is on herb tundra with no erect...

Subarctic rivers of northern Québec (Nunavik, Canada) unveil a potential pathway for waterborne release of greenhouse gases generated through mobilization of organic matter in...

Northern peatlands cover approximately four million km², and about half of these peatlands are estimated to contain permafrost and periglacial landforms, like palsas and peat...

This dataset compiles radiocarbon (14C) dates obtained from soil and lake sediment samples collected at Bylot Island, Nunavut. Bulk soil/sediment samples and, when present,...

Data are from Nikku Island in Nunavut, Canada. It contains data from air and ground temperatures, air humidity, solar radiation, wind speed and direction. The available datasets...

Data are from the Nastapoka river region in Nunavik, Quebec, Canada. It contains data from air and ground temperatures. The available datasets cover the period from 1996-1998....

Data are from the Biscarat river region in Nunavik, Quebec, Canada. It contains data from air and ground temperatures. The available datasets cover the period from 2005-2019....

Data are from the Sheldrake river region in Nunavik, Quebec, Canada. It contains data from air and ground temperatures. The available datasets cover the period from 1986-2019....

Data are from the Little Whale River region in Nunavik, Quebec, Canada. It contains data from air and ground temperatures, air humidity, solar radiation and wind speed and...

Computed tomographic (CT) scanning was used (August 2015) to analyze a 109 cm-long lake sediment core from a thermokarst lake in Bylot Island, Nunavut, Canada. The core was...

Ground-penetrating radar (GPR) lines were collected (May 2015) at Gull Lake (Bylot Island, Nunavut, Canada) using sleigh-dragged Sensors and Software PulseEkko GPR and 50 MHz...

This dataset presents an estimation of the organic matter content (by loss-on-ignition) and particle size (grain size analysis) in two lake sediment cores (109 cm, 114 cm) from...

This dataset presents all the fossil diatom species identified in a 109 cm-long lake sediment core from a thermokarst lake in Bylot Island, Nunavut, Canada. The core was...

Permafrost peatland lakes are an organic-rich subcategory of thermokarst lakes and ponds that are known for their high rates of greenhouse gas emissions (Matveev et al. 2016)....

Permafrost thawing mobilizes large quantities of organic carbon that was sequestered in Arctic regions over the last glacial cycle. Processes involved in the oxidation and...

Over the past decades, observations of buried glacier ice exposed in thaw-slump affected terrain of the Arctic indicate that considerable amounts of Pleistocene glacier ice...

The available dataset is the unique continuous measurement of the air temperature on the summit of Mont Jacques-Cartier (1263 m a.s.l.). This summit represents the highest peak...

Global warming projections still suffer from a limited representation of the permafrost-carbon feedback. Predicting the response of the permafrost temperature to climate changes...

It is presumed that significant quantities of carbon are stored in permafrost soils and that the thawing permafrost could substantially raise atmospheric carbon dioxide...
