Although the extent to which large-scale environmental change will affect birds that breed in arctic areas will vary among species, reduced reproductive success and population declines have been observed in long-distance migrants and species whose reproduction depends on non-climatic cues....

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. If unsafe bacterial levels are measured in water samples or if shoreline surveys identify pollution concerns, Environment and...

In 2022, the Watershed Hydrology and Ecosystems Research Division of Environment and Climate Change Canada (ECCC) uploaded a Lake Ice Database to the Government of Canada open data portal (https://data-donnees.ec.gc.ca/data/water/scientificknowledge/lake-ice-database/?lang=en). This companion...

The National Air Pollution Surveillance (NAPS) program is the main source of ambient air quality data in Canada. The NAPS program, which began in 1969, is now comprised of nearly 260 stations in 150 rural and urban communities reporting to the Canada-Wide Air Quality Database (CWAQD). Managed by...

During August 2013, September 2013, April 2018, May 2018, and June 2018, a research aircraft was deployed in the oil sands region. The flight paths of the aircraft were designed to measure air pollutants in plumes around the immediate vicinity of the major oil sands surface mining facilities...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The General status of wild species indicators summarize the general status of species in Canada. It also highlights the...

Water quality and ecosystem health data used to conduct a cumulative effects assessment of Lake Huron and St. Marys River nearshore waters in support of the Great Lakes Water Quality Agreement are included in this dataset. Data related to nearshore stressors is integrated into an overall...

Habitat and ecosystem data used to conduct a baseline survey of coastal habitat in Lake Huron, Georgian Bay, and St. Marys River are included in this dataset. The Lake Huron Survey methodology consists of four general steps; 1) delineating the coastal ecosystem into coastal units based on water...

This data set contains concentrations of total recoverable and dissolved metals in wastewater Influent (INF), Effluent (EFF), Landfill Leachate (LCH), Biosolids (BIOS) and Sludge (SLG) sampled from various Wastewater Treatment Plants (WWTPs) and Landfills across Canada.

This data set contains concentrations of polybrominated diphenyl ethers (PBDEs) in wastewater Influent (INF), Effluent (EFF), Landfill Leachate (LCH), Biosolids (BIOS) and Sludge (SLG) sampled from various Wastewater Treatment Plants (WWTPs) and Landfills across Canada. Scientific Publications:...

This data set contains concentrations of pharmaceuticals and personal care products (PPCPs) and hormones in wastewater Influent (INF), Effluent (EFF), Landfill Leachate (LCH), Biosolids (BIOS) and Sludge (SLG) sampled from various Wastewater Treatment Plants (WWTPs) and Landfills across Canada....

This data set contains concentrations of brominated flame retardants (BFRs) in wastewater Influent (INF), Effluent (EFF), Landfill Leachate (LCH), Biosolids (BIOS) and Sludge (SLG) sampled from various Wastewater Treatment Plants (WWTPs) and Landfills across Canada. Scientific Publications:...

The Canadian Air and Precipitation Monitoring Network (CAPMoN), operated by Environment and Climate Change Canada (ECCC), is designed to study the regional patterns and trends of atmospheric pollutants such as acid rain, smog, particulate matter and mercury, in both air and precipitation. The...

Monitoring of sea ice dynamics is of vital importance to our overall understanding of how the Arctic cryosphere is responding to changes in the Earth's climate. With the recent launch of the RADARSAT Constellation Mission (RCM) in 2019 and the continuing operation of the Sentinel-1 (S1) fleet,...

Humidex (Masterton and Richardson 1979) is an index developed by the Meteorological Service of Canada to describe how hot and humid the weather feels to the average person. In Canada, it is recommended that outdoor activities be moderated when the humidex exceeds 30, and that all unnecessary...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Emissions of harmful substances to air indicators track human-related emissions to air of 3 substances that are defined...

Weekly precipitation quantity has been measured at both at the primary meteorological site as well as at five other sites within the watershed. Daily precipitation quantity has been measured at the primary meteorological site until 2017. Weekly chemistry analysis of H+, major ions, nutrients and...

This study set out to provide an up-to-date portrait of the per- and polyfluoroalkyl substances (PFAS) contamination status in a freshwater food web from the St. Lawrence River (QC, Canada). Water, sediments, aquatic vegetation, invertebrates, and some fish species were targeted for analysis. All...

Ammonia (NH3) data were collected at regionally representative Canadian Air and Precipitation Monitoring Network (CAPMoN) sites. Radiello brand passive samplers were deployed at 2 or 5 m above the ground for two week periods and analyzed by the National Atmospheric Deposition Program (NADP)...

We investigated the stable isotope hydrology of Sable Island, NS, Canada over a four year period from September, 2017 until August, 2021. The δ2H and δ18O values of integrated monthly precipitation were weakly seasonal and ranged from -66 to -17 per mil and from -9.7 to -3.1 per mil,...
