The specific composition, biomass, vertical distribution and metal content of submerged and emergent aquatic plants in the St. Lawrence were evaluated. The riparian vegetation community of the St. Lawrence is characterized by the presence of extensive wetlands in the floodplain, a border of...

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...

Water quality monitoring data collected in priority tributaries to provide nutrient concentration data to estimate nutrient loads to the waters of the Great Lakes. Data is collected to advance the science to understand and address the complex problem of recurrent toxic and nuisance algae in the...

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...

On-going monitoring of the total column ozone and spectral ultraviolet radiation (UV) in Canada is carried out by the Canadian Brewer Spectrophotometer Network (CBSN). The data are used for periodic assessment of the state of the ozone layer, satellite data validation, and in forecasting ECCC’s...

Expanded Geographic Area (M9, M10, M11a, M12, BI1, RI1, SL1, SL2, QU1 [2013] and M9, M10, M11a, M12, BI1, BU1, BU2, RI1, SL1, SL2, QU1, MC2 [2011-March 2018]) Water quality chemistry data for 17 sites in the lower Athabasca River (LAR), the Peace and Slave rivers, and their tributaries, including...

This database contains model output files that were used in the 2021 Arctic Monitoring and Assessment Programme (AMAP) Assessment Report on Short-lived Climate Forcers (SLCFs) and subsequent journal publications. The datasets are stored here:...

In 2006, the Government of Canada initiated the Chemicals Management Plan (CMP), which takes action regarding chemicals that are harmful to human health or the environment. One element of the CMP is Monitoring and Surveillance, which generates data on the presence and levels of chemical...

Black carbon is a short-lived, small aerosol (or airborne) particle linked to both climate warming and adverse health effects. It is emitted from incomplete combustion of carbon-based fuels (i.e., fossil fuels, biofuels, wood) in the form of very fine particulate matter. Black carbon is not...

Shallow groundwater and the interaction of these waters with surface water in the mineable area of the Athabasca oil sands region are being examined to assess the role and importance of groundwater in the regional river ecosystems. Groundwater quality chemistry data is available from 182 shallow...

Water chemistry, 26 different metals, and polycyclic aromatic compounds (PACs) were measured at 21 wetland sites where studies of amphibian health are being conducted. The water chemistry measurements (pH, conductivity, total dissolved solids, etc.) are used to further assess water quality,...
