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,...

A high-resolution digital elevation model (DEM) is key to assessing habitat conditions, surface water connectivity, developing hydraulic models, and environmental change in the Peace-Athabasca Delta (PAD), Northern Alberta. Note that in this instance, DEM is a representation of the ground surface...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Land-based greenhouse gas emissions and removals indicator tracks exchanges of greenhouse gas (GHG) emissions and...

A collection of citation information for scientific and technical articles authored / co-authored by Environment Canada researchers.

The Canadian Wildlife Service - Ontario Region Biodiversity Atlas represents the Canadian Wildlife Service biodiversity portfolio across the Ontario portions of the Boreal Hardwood Shield (Bird Conservation Region 12) and Mixedwood Plains (Bird Conservation Region 13) ecozones. These data are the...

This is a database of modeled two-year (2016-2017) average dry deposition velocities (Vd) for 45 gaseous species and three particle size ranges at a 15 km by 15 km horizontal resolution across North America. The dry deposition schemes of Zhang et al. (2003) and Wu et al. (2021) were used for...

Meteorological Observations describe datasets that contain information about weather and climate conditions as available on the City-Pages of the Environment Canada WeatherOffice.gc.ca web site. These pages contain information about current weather conditions and past climate including...

Substituted phenylamine antioxidants (SPAs) are produced in relatively high volumes and used in a range of applications (e.g., rubber, polyurethane); however, little is known about their toxicity to aquatic biota. Therefore, current study examined the effects of chronic exposure (28 days) to four...

High-resolution ground terrain elevational data are key to assessing habitat conditions, surface water connectivity and environmental change in the Peace-Athabasca Delta (PAD), Northern Alberta. LiDAR (Light Detection and Ranging) is a remote sensing technology that has recently become more...

The World Meteorological Organization (WMO) Solid Precipitation Inter-Comparison Experiment (SPICE) officially began in the (Northern Hemisphere) Fall of 2012 with the objective of characterizing and providing guidance on the performance of automated systems for the in situ measurement of solid...

A series of surface climate parameters have been measured by members of the Climate Processes Section at the Borden Forest Research Station (44°19’N, 79°56’W) beginning in January 2006. The initial data included precipitation. In 2007, carbon dioxide fluxes from the soil (soil respiration) began...

Drought projections on seasonal to annual time scales are presented for Canada over the twenty-first century, based on the Standardized Precipitation Evapotranspiration Index (SPEI). Results make use of bias-corrected temperature and precipitation projections from 29 global climate models...

The Environmental Damages Fund (EDF), created by the Government of Canada in 1995, follows the Polluter Pays Principle to ensure that those who cause damage to the environment take responsibility for their actions. Prosecutors and judges can recommend that financial penalties (fines, awards...

This study examined the effect of two dinonylnaphthalene sulfonic acids (NSAs) on freshwater organisms: calcium dinonylnaphthalene sulfonate (CaDNS), and dinonylnaphthalene disulfonic acid (DNDS). Chronic effects were characterized by exposing fertilized fathead minnow eggs to sediment-associated...

The datasets and maps are associated with a research study. Annual total (dry + wet) deposition fluxes of nitrogen (nitric acid, nitrate and ammonium) and sulfur (sulfur dioxide and sulfate) were determined at 15 Canadian Air and Precipitation Monitoring Network (CAPMoN) sites from 2000 to 2018....

Multi-model ensembles for a suite of variables based on projections from Coupled Model Intercomparison Project Phase 6 (CMIP6) global climate models (GCMs) are available for 1850-2100 on a common 1x1 degree global grid. Climate projections vary across GCMs due to differences in the representation...

In 2012 samples of raw influent and final effluent wastewater from five municipal wastewater treatment plants at various locations in Canada (sites to remain anonymous, designated in this data file as MH, OX, Q, TB, U). Also, leachate was collected from three landfill sites (sites to remain...
