Investigations into the susceptibility of permafrost landscapes to thermokarst can be performed using various approaches, depending on the scale of investigation. In many cases,...

Measurements were carried out with a towed EM probe operated by a Basler BT67 aircraft. The survey was carried out on April 8, 2016, and captured predominantly first-year fast...

Muscle samples were taken from focal species of fish and tested for 60 elemental metals. We used 25 samples of each species that was available for multiple sites. Ten samples...

Glacier outlines were digitized from historical air photos (1959) and Landsat L1TP or Sentinel-2 L1C satellite imagery. Outlines for 1959-1982 were manually traced, and for...

Acoustic data was generated using a Sonic 2026 multibeam sonar system pole-mounted on the SY Vagabond between Aug. 24 and Sept. 11, 2020. This bathymetric dataset covers the SE...

Acoustic data was generated using a Sonic 2026 multibeam sonar system pole-mounted on the SY Vagabond between Aug. 12 and Sept. 07, 2019. This bathymetric dataset covers the SE...

Samples were collected at two sites in the Eastern Canadian Arctic (Figure 1) aboard the scientific icebreaker CCGS Amundsen. The sampling positions at biogenic and non-biogenic...

An oceanographic mooring was deployed from onboard the Arctic Research Foundation's R/V Martin Bergmann in the summer of 2016 and recovered the following year (9 Aug. 2016 to 30...

Cores where collected between 2012 and 2015 using a portable earth auger modified to fit a 8.25 to 10.8 cm core barrel. Cores where kept frozen at -20°C in the field and brought...

Arctic permafrost has been rapidly degrading in the past decades, releasing nutrients, solutes and water into soils and freshwater ecosystems. Ground ice and its distribution is...

Plastic is a general term that refers to a family of organic polymers derived from petroleum sources. In general, plastics are classified as polyester (PET), high-density...

Organic matter, upon dissolution into the aqueous state as dissolved organic matter (DOM), can undergo mineralization by microbes. There has been increasing effort to...

Permafrost degradation may lead to mobilization of carbon and nutrients and enhance microbial processing rates of previously frozen organic matter. Although the pool size and...

The data include a time series of locally-adjusted mean monthly average temperatures for the study area; a time series of the normalized difference vegetation index (NDVI) for...

Inuit are exposed to a wide range of environmental contaminants through their traditional diet, which includes significant amounts of fish and sea mammals. During the past 25...

This dataset represents a compilation of stream organic matter, nutrient, and isotope data for streams draining watersheds that are, and are not, affected by permafrost thaw...

The data collected were the following: 1) Audio/videos interviews with local hunters, elders, and women; 2) Contaminants data on mercury concentrations in Arctic char, ringed...

Inuit are exposed to a wide range of environmental contaminants through their traditional diet, which includes significant amounts of fish and sea mammals. Conversely, these...

The Littoral Chair, or Sentinel North Partnership Research Chair in Ecosystem Approaches to Health, was created in July 2019 and launched in February 2020 as a continuation of...

River damming alters nutrient fluxes along the land‐ocean aquatic continuum as a result of biogeochemical processes in reservoirs. Both the changes in riverine nutrient fluxes...
