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.

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...

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...

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....

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...

In 2011-2014 samples of groundwater and septic wastewater were sampled from various sites in Ontario, Canada. Most of the groundwater sites were impacted by septic wastewater plumes. The samples were analyzed for four artificial sweeteners (acesulfame, saccharin, cyclamate, sucralose),...

In 2018 samples of raw influent and final effluent wastewater from twelve municipal wastewater treatment plants at various locations in Canada (sites to remain anonymous, designated in this data file as NW, J, C, SM, JL, TB, GA, PA, PN, E, V, H). The samples were analyzed for four artificial...

In 2016-2019 water samples were collected at Lake of the Woods as part of a research program to determine sources and fate of nutrients in nearshore areas. These included samples of lake water, groundwater, streams, and septic wastewater. The samples were analyzed for nutrients (total and...

The objectives of the present long‐term study, spanning a 45 year period, were to 1) investigate the temporal trends of total mercury (THg; muscle and liver) and selenium (Se; liver) in ringed seals (Pusa hispida) from different regions of the Canadian Arctic; and 2) examine possible...

In 2018 samples of raw influent and final effluent wastewater from fourteen municipal wastewater treatment plants at various locations in Canada were analyzed for priority alkyl aryl sulfonates (AAS) using the methods developed by Van Stempvoort and Brown (2018). The analyses included seven...

Continuous, year-round measurement of stream stage that is later converted to flow using a stage-discharge relationship occurs on at/near the lake outflows and 2 other stations along the principal watershed tributary, Norberg Creek. Measurements ended in 2016. Supplemental Information The Climate...

A database of verified tornado occurrences across Canada has been created covering the 30-year period from 1980 to 2009. The data are stored in a Microsoft Excel spreadsheet, including fields for date, time, location, Fujita Rating (intensity), path information, fatalities, injuries, and damage...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Pulp and paper effluent quality indicator reports the percentage of acute lethality, biochemical oxygen demand and total...
