An Area of Concern (AOC) is a location where environmental quality is degraded compared to other areas in the Great Lake Basin resulting in the impairment of beneficial uses. A total of 43 AOCs were identified as a result of Annex 2 of the Great Lakes Water Quality Agreement (GLWQA).The...

Temporal changes (1970–2016) in St. Lawrence River wetlands were assessed between Cornwall and Québec to assess wetland response to cumulative anthropogenic pressures in the watershed. Emergent wetlands area and biomass of submerged aquatic vegetation (SAV) were contrasted among five regions...

Stormwater ponds have been widely used to control increased volumes and rates of surface runoff resulting from urbanization. Stormwater ponds have also been designed to provide multiple other benefits; including protection of downstream waters, sediment and habitat (land/aquatic) quality,...

This dataset contains the growth and survival data for Fathead minnow (Pimephales promelas) exposed to sediment from eleven sites within the St. Marys Area of Concern, as well as reference sediment (a mixture of sediment from two reference sites within Lake Erie, Long Point Marsh and Long Point...

Ringed seals (Phoca hispida) are harvested annually in Arviat and Resolute (Nunavut), Sachs Harbour (Northwest Territories) and Nain (Labrador) with the help of the communities in the context of an environmental monitoring program. Samples of meat, blubber, liver and kidney are collected for...

In the oil sands air monitoring component, nitrogen dioxide (NO2) and sulphur dioxide (SO2) levels are monitored by ground-based instruments, satellites and other measurements. Monitoring of air pollutants from satellites is becoming an alternative to surface and aircraft measurements, and allows...

Information received in response to the 2017 Inventory Update (chemicals and polymers) To increase transparency and to facilitate access to information on manufactured and/or imported substances in Canada, the Government of Canada is providing a summary of the information received in response to...

Meteorological forecasts are datasets that are products of current observations and are used to predict climate conditions for a future time and given location.

Designated as a Species of Special Concern in 2008, the entire range and potential area of occupancy for the Great Blue Heron is defined as terrestrial areas within the Coastal Douglas Fir and Coastal Western Hemlock Biogeoclimatic zones that are less than 10 km from a potential foraging area...

Environment and Climate Change Canada (ECCC) has been monitoring levels of persistent organic pollutants and heavy metals in seabird eggs collected from the St. Lawrence River and Gulf of St. Lawrence, Canada, since the end of 1960s. Two sentinel species were selected to monitor aquatic ecosystem...
