Permafrost thaw can considerably increase the transport of materials from land to freshwater systems, as chemical constituents locked up in previously frozen soils become...

This project takes a land, to water, to landscape approach to understanding the effects of fire on aquatic ecosystem function. We aim to explore how specific fire-induced...

An incubation experiment was conducted on board of the Canadian research icebreaker CCGS Amundsen between 6 and 15 August 2015. The water was collected near the nitracline at 38...

To determine microbial community composition and their potential activities in freshwater systems throughout the Lake Hazen watershed (81N; 71W), triplicate samples were taken...

A warming climate is rapidly changing the distribution and exchanges of carbon within high Arctic ecosystems. Few data exist, however, which quantify exchange of both carbon...

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...

During the ArcticNet annual cruises of the research icebreaker CCGS Amundsen, characteristics of the surface sea water (temperature, salinity, dissolved CO2 and O2) are...

In May 2015, we realized a survey of the sea ice and snow conditions in Station North (North Greenland) where we measured the sea ice and snow thickness and measured the...

We have collected subsamples of sediments retrieved from Baffin Bay during the ArcticNet funded Hidden Biodiversity expedition, in order to characterize their microbial...

The concentration of dissolved methane was measured using a PP1 methane and non-methane hydrocarbons analyzer (Peak Laboratories). Concentrations of methane in surface water (5...

Environmental and geochemical variables were compared at both the local and regional scale with the use of multivariate analysis. A principal components analysis indicated that...

Here we present evidence for highly dynamic ikaite precipitation and dissolution in sea ice grown at an outdoor pool of the Sea-ice Environmental Research Facility (SERF) in...

Archived sediment samples from 25 sediment cores, which were collected along an oceanographic section spanning Canada's Arctic margin during the International Polar Year...

Melt pond formation is a common feature of the spring and summer Arctic sea ice. However, the role of the melt ponds formation and the impact of the sea ice melt on both the...

From under the ice in May, and throughout the open water season, dissolved GHG samples were collected from East and West lakes. Surface dissolved GHG samples were collected in...

The concentrations of nitrate, nitrite, orthophosphate and orthosilicic acid were determined on fresh water samples using an Autoanalyzer 3 (Bran+Luebbe) with colorimetric...

The concentrations of nitrate, nitrite, orthophosphate and orthosilicic acid were determined on fresh or frozen water samples using an Autoanalyzer 3 (Bran+Luebbe) with...
