The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Ability of the agricultural landscape to support wildlife indicator maps the relative value of Canada's agricultural...

The concentrations of contaminants in seawater influence what is detected in marine mammals and seabirds and levels and time trends of the contaminants in the ocean has been identified as a knowledge gap by the Northern Contaminants Program (NCP). Samples were analyzed for persistent organic...

The purpose of this study is to examine trends over time of mercury and other trace elements, as well as legacy and new persistent organic pollutants (POPs) in landlocked Arctic char collected annually from lakes near the community of Resolute Bay on Cornwallis Island (Amituk, Char, North, Small,...

The Acid Sensitive Lakes Study in the Atlantic Canada was initiated in 1983 by Environment and Climate Change Canada, to evaluate the impact of acid atmospheric pollutant on aquatic ecosystem. Originally, the study focused on the aquatic and terrestrial effects of acid precipitation, but now it...

These datasets contains depth profile of perfluoroalkyl acids (PFAAs) concentrations collected from snow on the Devon Ice Cap from 2005-2015. Perfluoroalkyl acids (PFAAs) are present in remote regions where no local sources exist. To improve understanding of long-range transport of perfluoroalkyl...

Ringed seals (Phoca hispida) are harvested annually in Arviat and Resolute (Nunavut), Sachs Harbour (Northwest Territories) and Nain (Labrador) with the help of the communities in the context of an environmental monitoring program. Samples of meat, blubber, liver and kidney are collected for...

Black carbon is a short-lived, small aerosol (or airborne) particle linked to both climate warming and adverse health effects. It is emitted from incomplete combustion of carbon-based fuels (i.e., fossil fuels, biofuels, wood) in the form of very fine particulate matter. Black carbon is not...

Water chemistry, 26 different metals, and polycyclic aromatic compounds (PACs) were measured at 21 wetland sites where studies of amphibian health are being conducted. The water chemistry measurements (pH, conductivity, total dissolved solids, etc.) are used to further assess water quality,...

Metals in Mallards (pooled 2013 collections) Adult male mallards were collected in 2013 in the area surrounding five Alberta communities south of the Athabasca oil sands industrial region (Mayerthorpe, Barrhead, Lac La Biche, St. Paul and Vermilion) and from two communities north of the...

Assessing polycyclic aromatic hydrocarbon and naphthenic acid concentrations in soils collected in 2012 – Field and Laboratory Assessment of Contaminants The concentrations of polycyclic aromatic hydrocarbons (PAHs) and naphthenic acids (NAs) were measured in soil samples collected in 2012....

Plant species richness, composition, and soil chemistry parameters were assessed in wetlands and uplands in the oil sands region of northern Alberta. The concentrations of metals and polycyclic aromatic hydrocarbons (PAHs) were measured in soil and plant samples collected from 2012-2014, and...

The Great Lakes Sediment Database (also known as the National Water Research Institute (NWRI) Sediment Archive) is an archive of data on the sediments of the Great Lakes, their connecting channels, and the St. Lawrence River which was collected by NWRI and in cooperation with other agencies...

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 indicators provide a measure of the ability of river water across Canada to support...

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...

This project is part of the Northern Contaminants Program core monitoring and looks at contaminant levels in landlocked Arctic char from lakes in Nunavut over time. Landlocked char are the only top predators in most Canadian high Arctic lakes and, therefore, can serve as a sentinel species for...

The Joint Canada-Alberta Implementation Plan for Oil Sands Monitoring (Environment Canada and Alberta Environment 2012) included the initiation of new biomonitoring sites on the Lower Athabasca River mainstem and its major tributaries following the study designs proposed in the Integrated...

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...

During August 2013, September 2013, April 2018, May 2018, and June 2018, a research aircraft was deployed in the oil sands region. The flight paths of the aircraft were designed to measure air pollutants in plumes around the immediate vicinity of the major oil sands surface mining facilities...

Neonicotinoid insecticides are environmentally persistent and highly water-soluble, and thus are prone to leaching into surface waters where they may negatively affect non-target aquatic insects. Most of the research to date has focused on imidacloprid, and few data are available regarding the...

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...
