On Bylot Island (Nunavut), large gullies developed in continuous permafrost terrains were observed in the valley of the glaciers C-79 and C-93. Thermo-erosion gullies are rapid...

Datasets in this issue of Nordicana-D (D8) include borehole data collected on Bylot Island, Nunavut, northeastern Canada. The measurement sites are part of the SILA network of...

Biological in situ observation of habitats of the high Arctic, including their physical and geochemical characteristics, and DNA sample collection were made at all sites....

Permanent plots were established and georeferenced (approx. 20 m x 20 m) in Bylot Island. Vegetation (plant species diversity and cover) and basic biophysical parameters...

In 2005, vegetation survey of 2m x 2m quadrats at 10 m, 20 m and 40 m from the gully edge along 4 transects perpendiculars to the main gully were made. In...

Sediment methylation and demethylation rates were measured by short-term incubations of stable isotopes of inorganic and methylmercury in sediment cores. Methylmercury...

Surface sediments from 20 lakes and ponds in Sirmilik National Park were collected using a gravity corer or an Ekman dredge. Water samples were taken for detailed chemical...

Digitalisation of the thermo-erosion gullies was accomplished using a Trimble differential GPS (model Pathfinder Pro XRS with a TSC1 data collector). Differential correction was...

Limnological profiles done with a YSI multiparameter probe (T°, pH, conductivity, oxygen). Discrete water samples collected for nutrients, major anions and cations, dissolved...

The fieldwork consisted of excavating stratigraphic exposures (up to 5 meters height) inside the permafrost. These sections were excavated to clarify the depositional sequences...

Arctic freshwater ecosystems are important habitats for northern wildlife. Arctic climate impact studies suggest that global change could result in major modifications and...

Carbon fluxes and concentrations (carbon dioxide, CO2, and methane, CH4) were measured in various aquatic and terrestrial ecosystems across the eastern Canadian Arctic. Firstly,...

We are monitoring the nesting activity of shorebirds on the island in 2 areas distant of approximately 30 km. We are conducting regular searches throughout the breeding season...

We are monitoring the variations in arthropod abundance and activity throughout the whole summer. Modified Malaise traps (pitfall trap with vertical mesh screen and bottle trap...
