Lake sediment cores were collected from several locations in Canada as part of the historic mercury and heavy metal deposition trend, analysis, and research component of the Clean Air Regulatory Agenda/Climate Change and Air Pollutant (CARA/CCAP) and Oil Sands Monitoring (OSM) programs. The...

Recent and historical deposition of mercury (Hg) are examined over a broad geographic area from southwestern Northwest Territories to Labrador and from the U.S. Northeast to northern Ellesmere Island using dated sediment cores from 50 lakes (18 in midlatitudes (41-50 degrees North), 14 subarctic...

The Canadian Environmental Sustainability Indicators CESI program provides data and information to track Canada's performance on key environmental sustainability issues. The Protected Areas indicators report the amount and proportion of Canada's land and freshwater and marine area that is...

The Canadian Meteorological Centre CMC produces Numerical Weather Prediction NWP as one of the key inputs to the Meteorological Service of Canada's overall public weather and environmental prediction and warning process. The raw data from NWP is made available to outside users who may use it...

The bioaccumulation of a broad range of pharmaceuticals and personal care product chemicals (PPCPs) was studied in Cootes Paradise Marsh (CPM), an urban wetland that receives tertiary treated municipal waste waters as well as urban storm runoff. PPCPs were measured in caged and wild goldfish, as...

This dataset contains a compilation of Migratory Bird Sanctuaries, National Wildlife Areas, Key Terrestrial Sites, Key Marine Sites, Important Bird Areas, RAMSAR Wetlands, and newly identified important areas for Birds within Nunavut.

The Special Studies presented on this site are special measurement campaigns (with durations of several weeks to several years) carried out by the Air Quality Research Division of Environment Canada and its government, university and industry collaborators. The Special Studies data sets consist...

Provides public access to archived sediment data daily loads, daily concentration, instantaneous concentration for stations of interest using search criteria. The sediment monitoring program discontinued in 1989. Archived sediment data are disseminated both online and offline via MS Access file.

Climate Data Products at Environment Canada comprise of four different datasets: Almanac Averages and Extremes, Monthly Climate Summaries, Canadian Climate Normals, and Canadian Historical Weather Radar. Almanac Averages and Extremes provides average and extreme temperature and precipitation...

These daily forecasts describe the ice edge using latitude and longitude coordinates and for each marine area, the total ice concentration, the predominant ice stage of development and the concentration of the oldest ice type. Warnings are issued as appropriate. The forecasts are valid from the...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Releases of Harmful Substances to the Environment indicators track anthropogenic releases to air and water of three toxic...

This file includes the spatial boundaries for the Pacific Great Blue Heron Potential Area of Occupancy for its entire Canadian range. The Potential Area of Occupancy is a simple model that highlights the heron's preferred forest habitat at a high level. Potential Area of Occupancy is defined as...

Synthetic dyes are extensively used in many industrial and consumer products, including paper productions, leather tanning, food colouring, personal care products (examples being; hair colour, deodorant etc.). Synthetic dyes are also used in textile paints. No method has been able to completely...

The Canada’s Changing Climate Report (www.changingclimate.ca/CCCR2019), led by Environment and Climate Change Canada, is about how and why Canada’s climate has changed and what changes are projected for the future. Datasets supporting the results produced for the Canada’s Changing Climate report...

Data on location and timing of surveys, ecological descriptions, environmental attributes wind, weather etc , bird observations point count data, species at risk playback data , habitat data ecological vegetation data, habitat mapping etc . Data were collected from across the Oilsands Areas of...

Population trend estimates based on data collected through the North American Breeding Bird Survey (BBS), for approximately 300 Canadian bird species. The trend results are Canadian trends and thus use data from Canadian BBS routes only. Results are updated annually; these estimates use BBS data...

Engineering Climate Datasets encompasses Intensity-Duration-Frequency IDF Files, Canadian Weather Energy and Engineering Datasets CWEEDS , and Canadian Weather Year For Energy Calculation CWEC . IDF tabulates and graphs short-duration rainfall statistics across 563 locations in Canada. CWEEDS...

Water level and discharge data are available from Water Survey of Canada’s Hydrometric Network. The Water Survey of Canada (WSC) is the national authority responsible for the collection, interpretation and dissemination of standardized water resource data and information in Canada. In...

Long-term freshwater quality monitoring data for over 40 sites in the St. Lawrence River basin for the past 15 years or longer for nutrients, metals, major ions, and other physical-chemical variables are included in this dataset. Monitoring is conducted by Environment and Climate Change Canada...

The Pacific 2001 Air Quality Study (PAC2001) was conducted from 1 August to 31 September, 2001 in the Lower Fraser Valley (LFV), British Columbia, Canada. The study consisted of a number of research projects organized to address several issues related to ambient particulate matter and ozone. A...
