Environment and Climate Change Canada

Multi-model ensembles of sea ice concentration based on projections from twenty-eight Coupled Model Intercomparison Project Phase 5 (CMIP5) global climate models are available for 1900-2100. Specifically, the 5th, 25th, 50th, 75th and 95th percentiles of the monthly, seasonal and annual ensembles...

Multi-model ensembles of sea ice thickness based on projections from twenty-six Coupled Model Intercomparison Project Phase 5 (CMIP5) global climate models are available for 1900-2100. Specifically, the 5th, 25th, 50th, 75th and 95th percentiles of the monthly, seasonal and annual ensembles of...

Seasonal and annual multi-model ensembles of projected relative change (also known as anomalies) in mean precipitation based on an ensemble of twenty-nine Coupled Model Intercomparison Project Phase 5 (CMIP5) global climate models are available for 1901-2100. Projected relative change in mean...

The atlas provides printable maps, Web Services and downloadable data files representing seabirds at-sea densities in eastern Canada. The information provided on the open data web site can be used to identify areas where seabirds at sea are found in eastern Canada. However, low survey effort or...

This dataset contains 21 statistics of wind and waves calculated from hourly reanalysis data of historical surface winds and ocean surface waves for the Canadian East Coast for the period 1954-2018 (each statistic has an annual, 4 seasonal, and 12 monthly values). These data can be used for...

Tributary Biomonitoring (Lower Athabasca River) Benthic macroinvertebrates, comprising insects, crusteaceans, molluscs and worms, represent a group of organisms used widely in environmental monitoring programs as early warning indicators to assess the effects of change in water quality...

The Fish Contaminants Monitoring Program (FCMP) was initiated in 1976. The objective is to collect a variety of biological samples in freshwater environments for the purpose of determining ecosystem contaminant levels. Environment and Climate Change Canada (ECCC) collects biological samples from...

NETCARE is a network comprised of researchers from ten Canadian universities (University of Toronto, University of British Columbia, Université du Québec à Montréal, University of Waterloo, Université du Québec à Rimouski, Laval University, Dalhousie University, University of Calgary, Université...

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,...

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...

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...

Acid-Sensitive Lakes Nine hundred and thirty-three lakes located in Saskatchewan, Alberta and the Northwest Territories were sampled to establish current acidification status. Of the 933 lakes, 244 (or 26%) are considered acid sensitive, almost always because of naturally low calcium and...

Aquatic bird eggs are being collected for contaminants analysis. Egg collections in the Peace-Athabasca Delta area support Parks Canada’s activities at Wood Buffalo National Park and the multi-stakeholder Peace-Athabasca Ecosystem Monitoring Program. This monitoring activity employs repeated...

Benthic invertebrates monitoring includes both lotic (rivers/streams) and lentic (wetlands) ecosystems. Aquatic biomonitoring provides a direct measure of change in biotic populations and communities in relation to benchmark or reference conditions and can help identify the ecological effects of...

Deltaic Wetlands Biomonitoring Wetland macroinvertebrates, comprising insects, crustaceans, molluscs and worms represent a group of organisms forming a critical food resource for consumer organisms (e.g. fish, birds), that are used widely in environmental monitoring programs to assess both the...

Particle data from Canadian and U.S. ground-based monitoring networks from 1982 forward include the following: Aerosol Optical Depth (AOD); Aerosol Size Distribution; Aerosol Number; Aerosol Chemical Composition; Particulate Matter Mass; Particulate Matter <= 2.5 microns (PM2.5);...

Information received in response to the data gathering initiative on certain substituted diphenylamine substances (2012). To increase transparency and to facilitate access to information on substances in commerce in Canada, the Government of Canada is providing the summary of the information...

Information received in response to the notice with respect to certain aromatic amines and aromatic azo and benzidine-based substances (2011). To increase transparency and to facilitate access to information on substances in commerce in Canada, the Government of Canada is providing the summary of...

The CanESM2 large ensembles are 50-member perturbed initial condition ensembles from 1950 to 2020, with all historical forcings (historical), solar and volcanic forcings only (historicalNat), anthropogenic aerosols only (historicalMisc, p4), and ozone only (historicalMisc, p6). The model,...
