This dataset, in part, is composed of aquatic benthic macroinvertebrate taxa lists generated as part of the Sequencing the River for Environmental Assessment and Monitoring (STREAM) project (see www.STREAM-DNA.com for more details). Benthic macroinvertebrate sampling was based upon existing...

The Air Quality Health Index (AQHI) is a scale designed to help quantify the quality of the air in a certain region on a scale from 1 to 10. When the amount of air pollution is very high, the number is reported as 10+. It also includes a category that describes the health risk associated with the...

The Hudson Bay Lowlands (HBL) is the wettest ecozone in Canada with 80% of its area covered by wetlands. It forms the third largest wetland in the world and is composed almost entirely of permafrost and non-frozen subarctic peatlands that store more carbon in the first 2 m of soil than the total...

Climate warming and permafrost thaw induced land cover change are well documented in much of the circumpolar north. The frequent exposure of Precambrian continental crust in Canada’s Taiga Shield ecoregion could mean impacts of land cover change documented in other regions without this feature...

The purpose of this study was to assess the release and characterization of forms of silver nanoparticles (AgNPs) in urban effluents across Canada. Samples were collected from various wastewater treatment plants and were measured and analyzed using the single particle ICP-MS technique...

Due to the curvature of the Earth, the height of a radar beam, in relation to the ground, increases as it travels further from the radar. When the radar is pointed down near the ground (a low elevation angle), the beam starts off near the ground but then its height above the ground slowly...

DPQPE product: DPQPE stands for: Dual Polarization Quantitative Precipitation Estimation. The DPQPE product is available only for S-Band radars. It is a two-dimensional representation of the precipitation rate estimated by the lowest sweep of the radar (elevation angle of 0.4 degrees for the...

This product shows the rain accumulation, in mm, over the last 24 hour period based on PRECIP-ET and DPQPE. For PRECIP-ET, this product is available every 10 minutes for C-Band radars and every 6 minutes for S-Band radars. For DPQPE, this product is available every 6 minutes.

The PRECIP-ET (PRECIPET on images) is an extension of the PRECIP product (hence the use of ET in the product name). Compared to the previous PRECIP product, the PRECIP-ET performs a suite of additional quality control (QC) tests and tracks issues better. For example, Doppler filters might be...

The Air Pollutant Emission Inventory (APEI) is an annual report of air pollutant emissions across Canada published by Environment and Climate Change Canada. The report details the release of air pollutants from all known of sources since 1990. The APEI serves many purposes, including:...

Water quality and ecosystem health data collected using a risk-based monitoring approach to support the Great Lakes Water Quality Agreement are included in this dataset. By conducting regular, systematic measurements of the physical, chemical and biological conditions of the Great Lakes...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Water quality in Canadian rivers indicator provide a measure of the ability of river water across Canada to support...

This study aimed to develop and improve upon analytical methods and sampling techniques for detecting oil sands process-affected water (OSPW) seepage from mining containments and discriminating any seepage from the natural bitumen background in groundwaters influenced by the Alberta McMurray...

Water samples were collected in two headwater stream catchments (Nissouri Creek, Cedar Creek) of the Thames River 2017-2019 to help characterize the contribution of groundwater seepage to water quality. Groundwater wells and surface streams were sampled over the course of the study. The...

The Rusty Blackbird (Euphagus carolinus) breeds in boreal forest wetlands across North America, and winters in the southeastern USA. This species is listed under Canada’s Species at Risk Act as Special Concern due to population declines. For the study, 1220 Rusty Blackbirds were captured in...

We conducted a species-specific survey for Common Nighthawk (Chordeiles minor) near the northwestern limit of the species’ breeding distribution, in order to investigate relative abundance and also to determine whether a species-specific survey protocol being established for Canada would be...

We documented seasonal and daily activity patterns of Common Nighthawk (Chordeiles minor) near Whitehorse, Yukon, to evaluate the appropriateness at higher latitudes of national survey protocols for this species. Nighthawk vocalizations and audible aerial displays were detected at four locations...

Historical water quality data measured on a continuous basis at over 23 locations across Canada is included in this dataset. Most locations include hourly temperature, dissolved oxygen, pH, specific conductance and turbidity. Data are collected by Environment and Climate Change Canada (ECCC) and...

We studied the community structure of crustacean zooplankton along the biogeographical zones of the St. Lawrence River (Québec, Canada), to evaluate how the riverscale hydrological network formed by water masses, and local-scale aquatic environment, influenced the distribution of zooplankton...
