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

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'...

Phytoplankton communities in Arctic lakes and fiords are diverse despite oligotrophic conditions. Phytoplankton pigment analyses allow the estimation of the potential primary...

Sustainability of existing infrastructure and new projects in the Arctic rely on a detailed knowledge of the thermal and geotechnical properties of permafrost, which is required...

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...

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...

Limnological profile and cytometry of Ward Hunt Lake, located on Ward Hunt Island, Nunavut, Canada. Data were collected during a field campaign in July 2022. The various...

Properties of Arctic lakes vary depending on the type of soil, major sources of water, size of the lake, elevation and climatic conditions among others. We studied 35 lakes of...

Lemming abundance and demography are monitored using three methods: Capture by snap trapping was done using Museum Special traps at three sites during the summer from mid-July...

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,...

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...

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....

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

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...

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...

Northern terrestrial ecosystems are undergoing rapid transformation, potentially affecting the chemistry and microbial community structure in rivers flowing through them. From 2...

Establishing new ecological baselines and initiating monitoring schemes on Arctic vegetation are critical to monitor, predict, and manage current and future impacts of climate...

The data are collected from three stations in the Forêt d’enseignement et de recherche de Macpès which is located about 20 km south of the city of Rimouski in Quebec, Canada....

Following the 2006-2012 action plan on climate change entitled "Le Québec et les changements climatiques, un défi pour l’avenir", the Government of Quebec implemented the tools...

High Arctic lakes are important sentinels of ongoing climate changes, although many details about their functioning remain to be fully understood. Since 2017, the Stuckberry...
