In northern regions, the seasonal Freeze Thaw (FT) is among climatic phenomenon having major impacts on terrestrial photosynthesis and respiration as well as soil evaporation...

In ice-rich hummocky terrains spanning broad swaths of the Canadian Arctic, accelerating permafrost thaw and terrain subsidence (thermokarst) are exposing materials that were...

Monitoring seasonal variation in arthropod abundance above or near the soil surface primarily allows us to determine the interannual availability of food resources for...

The Lapland longspur (Calcarius lapponicus) is one of the most abundant and visible terrestrial songbird breeding in the Arctic. As other Arctic-nesting birds, they are...

Nest searches are carried out on foot from our main field station since 1989 and from a secondary field camp inside the main goose colony since 1992. Nests are found during...

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...

These data were collected as a part of the Slave Province surficial materials and permafrost study (SPSMPS) which took place near the Ekati mine, north of Lac de Gras. Data...

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...

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...

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...

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...

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

While most ecological studies focus on the impact of climate change on some populations or species, broader, ecosystem-based information is needed to better predict the future...

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...

Data are from the Grands-Jardins park in Charlevoix, Quebec, Canada. It contains data from air and ground temperatures, wind speed and direction and the average snow height. The...
