These data were obtained on shrub tundra (Salix richardsonii) in the Canadian high Arctic, in Qarlikturvik valley on Bylot Island at 73°11'N, 79°45'W. A 1-year time series of...

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

In formerly glaciated permafrost regions, extensive areas are still underlain by a considerable amount of glacier ice buried by glacigenic sediments. Although the extent and...

This dataset comes from a borehole located along the Alaska Highway at the Beaver Creek Road Experimental Site (BC-RES), Yukon, Canada. Measurements were made every 4h...

This dataset provides a long-term weather record from Purple Valley, Ellesmere Island. This location is near the head of Milne Fiord and can serve as an index location for the...

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,...

Long-term monitoring of an ice patch at Ward Hunt Island on the northern coast of Ellesmere Island (83°06'N 074°10'W; Nunavut, Canada) provides information on the seasonal and...

Ice covers northern lakes for much of the year and has biological and biogeochemical properties that differ from those in the underlying water. Since 2017, we have studied lake...

To assess the impact of two sheds used to limit permafrost warming and degradation on a road embankment, soil surface and air temperatures were recorded with iButton sensors...

A network of temperature and humidity sensors was deployed near Yellowknife, Canada to establish 28 distinct study sites reflecting landscape variability. The field campaign was...

This data set is a compilation of in-situ snow cover measurements acquired during multi-site and multi-date measurement campaigns. It includes snow depth, bulk density and snow...

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...

The number of glacial lakes is rapidly increasing with glacial retreat in the Canadian High Arctic, yet very little is known about the biology of these aquatic environments....

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...

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

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...

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...

Dissolved organic matter (DOM) leaching from thawing permafrost may have feedback effects on climate if it is efficiently mineralized into greenhouse gases (GHG). Yet, many...

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...
