East lake water was collected and filtered using a glass filtration apparatus and precombusted 0.7 μm GF/F glass fibre filters. Sample water was then distributed into 40 mL...

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...

La méthodologie combine l’utilisation d’une image satellite multispectrale à haute résolution collectée en 2017 par le satellite Pleiades-1B et des photographies aériennes...

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...

Study lakes and ponds were sampled for water chemistry, including dissolved organic carbon (DOC), total nitrogen (TN), total phosphorus (TP), chlorophyll a (Chla), anions,...

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...

The C-band scatterometer was mounted at 2.6m height and scans were made at 5° intervals over the 20-65° radar incidence angle range, and an azimuthal width of 40° was used,...

RADARSAT-2 and TerraSAR-X SAR acquisitions were incrementally acquired over the study site and over aerial photography flight lines. Acquisitions began prior to Arctic-ICE 2012...

During each survey, an ¿X¿ pattern was flown over McDougall Sound at 1524 m (5000 ft), followed by a grid pattern over the primary field study site at 610 m (2000ft). On 02...

Polar Bear Pass (PBP) National Wildlife area is a large regional wetland (100 km2) on Bathurst Island, and is considered one of the most critical ecological sites on the island....

The objective of this work was to examine the ecological variability of lakes and ponds within Wapusk National Park (WNP) and the surrounding region and collect baseline...

Water Depth and chemistry was measured during the ice free season. Biology was sampled using a Kick and Sweep method using a D-net (500 um mesh) with three transect per pond....

We sampled 27 tundra lakes and ponds during July and August of 2002, 2003 and 2004. Five of the water bodies were located in coastal subarctic northern Quebec (in the vicinity...

Polar Bear Pass (PBP) National Wildlife area is a large regional wetland (100 km2) on Bathurst Island, and is considered one of the most critical ecological sites on the island....

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

Water from 5 stations near Churchill, MB were sampled once per week. Samples were collected by hand or with a pump unit, always following trace metal sampling techniques (e.g....

Clear acrylic chambers were used to monitor benthic CO2 uptake and release from sediments in a shallow pond from June to August 2007 near Churchill Manitoba. Fluxes were obtain...
