GPR profiles and ground ice contents of permafrost cores in Cape Bounty, Melv...
Investigations into the susceptibility of permafrost landscapes to thermokarst can be performed using various approaches, depending on the scale of investigation. In many cases,... -
Total suspended solid data from streams draining permafrost thaw slumps on th...
This dataset represents a compilation of total suspended solid (TSS) concentrations (in mg/L) and watershed yields (in mg/s/km2) for streams draining watersheds that are, and... -
Shallow (12 cm) ground temperatures for 7 ice-wedge troughs and 2 polygon cen...
Near surface ground temperatures were collected at the centre of 7 ice-wedge troughs and 2 polygon centres using iButton thermochron temperature sensors. Each sensor was buried... -
Ice-wedge transect thaw depths during 2017 and 2018 thaw seasons, Fosheim Pen...
Thaw depths (cm) were collected using a 1 m permafrost probe weekly to biweekly for transects of 7 ice-wedge troughs (IW1 - IW7) and 2 polygon centres (P1 and P2) between 3... -
Microbial methane dynamics in subarctic permafrost thaw lakes (Whapmagoostui-...
Samples were collected annually in August in the thermokarst lakes of Nunavik, as part as the ADAPT project (Arctic Development and Adaptation to Permafrost in Transition),... -
2018 Active Layer and Permafrost Geophysics and Land Subsidence Analysis
Two contrasting study sites were studied over the course of six weeks. Low level unmanned aerial vehicle (UAV) flight campaigns, land surveys, and continuous measurements by... -
Photomineralization of the organic matter mobilized by permafrost thawing in ...
The experimental design includes laboratory experiments under natural light conditions, as well as in-situ field experiments. Two study sites have been selected for the PhD... -
Oxygen dynamics and microbial respiration in subarctic permafrost thaw lakes ...
Samples will be collected annually in August from thaw ponds in Nunavik as part as the ADAPT project (Arctic Development and Adaptation to Permafrost in Transition). Automated... -
Influence of geomorphology and organic matter lability on the variability in ...
The PhD fieldwork spans from summer 2014 to summer 2016, however this project relies on the limnological research conducted continuously on Bylot Island since 2005. Limnological... -
Life under the ice: extreme conditions or oases? Hudsonie21 project on winter...
Thermokarst lakes are widespread in subarctic regions and contribute to global carbon (C) cycling. The recent degradation of permafrost means that the basic limnological and... -
Mercury, Methylmercury and Limnological Data in Arctic and Subarctic Ponds in...
Study lakes and ponds were sampled for water chemistry, including dissolved organic carbon (DOC), total nitrogen (TN), total phosphorus (TP), chlorophyll a (Chla), anions,... -
Diatom assemblages in surficial sediments of shallow lakes in Hudson Bay Lowl...
Samples of surficial sediments (upper 1-2 cm) were collected from 37 shallow lakes of Wapusk National Park using a coring tube (38-mm internal diameter). Lakes were located in... -
Greenhouse gas emissions from permafrost thaw ponds in the Canadian Arctic: i...
We sampled gas, water, ice, permafrost and lacustrine sediment in different types of aquatic systems: polygonal ponds, collapsed ice-wedge trough ponds, and larger lakes (1... -
Thermokarst Pond Structure and Dynamics in northern Québec (Nunavik)
Building on recently published work dealing with sedimentological dynamics in subarctic thermokarst ponds (Bouchard et al. 2014; Arctic, Antarctic & Alpine Research), we... -

The project involved building a GIS-based predictive model that integrates spatial data on retrogressive thaw slumps, sacred sites, Gwich'in toponyms, Gwich'in traditional land... -
Ecology of planktonic cyanobacteria in Subarctic permafrost thaw lakes (Whapm...
The field campaigns were conducted in August on the lakes and ponds in five different locations within the Subarctic discontinuous permafrost zone. Each sampling included... -
Past and present siliceous algal communities in subarctic thermokarst landsca...
Our study will be focused on both planktonic and periphytic species. We will analyze the present-day composition of these communities for each type of substratum and habitat... -
