To determine if levels of contaminants such as mercury or persistent organic pollutants can affect the pigmentation characteristics of semipalmated sandpiper (Calidris pusilla) eggs laid at Arctic sites.

Lake Winnipeg usually experiences ice cover during December to May (South Basin)/ June (North Basin). This dataset are water quality data collected in the South Basin of Lake Winnipeg during the winter of 2024, for the Freshwater Lake Winnipeg project. The bottom part (10cm) of ice-core samples...

Stormwater ponds have been widely used to control increased volumes and rates of surface runoff resulting from urbanization. Stormwater ponds have also been designed to provide multiple other benefits; including protection of downstream waters, sediment and habitat (land/aquatic) quality,...

Meteorological forecasts are datasets that are products of current observations and are used to predict climate conditions for a future time and given location.

Water quality monitoring data collected in priority tributaries to provide nutrient concentration data to estimate nutrient loads to the waters of the Great Lakes. Data is collected to advance the science to understand and address the complex problem of recurrent toxic and nuisance algae in the...

Expanded Geographic Area (M9, M10, M11a, M12, BI1, RI1, SL1, SL2, QU1 [2013] and M9, M10, M11a, M12, BI1, BU1, BU2, RI1, SL1, SL2, QU1, MC2 [2011-March 2018]) Water quality chemistry data for 17 sites in the lower Athabasca River (LAR), the Peace and Slave rivers, and their tributaries, including...

This database contains model output files that were used in the 2021 Arctic Monitoring and Assessment Programme (AMAP) Assessment Report on Short-lived Climate Forcers (SLCFs) and subsequent journal publications. The datasets are stored here:...

Shallow groundwater and the interaction of these waters with surface water in the mineable area of the Athabasca oil sands region are being examined to assess the role and importance of groundwater in the regional river ecosystems. Groundwater quality chemistry data is available from 182 shallow...

The d4PDF-WaveHs dataset represents the first single model initial-condition large ensemble (SMILE, 100-member) of historical significant ocean wave height (Hs) at a global scale. It was produced using an advanced statistical model with predictors derived from Japan's database for policy...

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 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...

Two precipitation measurement super-sites were established in Saskatchewan in anticipation of the World Meteorological Organization (WMO) intercomparison initiatives for automated in-situ measurement of solid precipitation and snow (2013-2015) and to provide infrastructure support for exploring...

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...

Our current understanding of the factors that influence where birds nest is incomplete, yet such information is important for accurate demographic assessments. To address questions related to spatial distributions of shorebird nests and to evaluate factors that may affect nest distribution in...

Although the extent to which large-scale environmental change will affect birds that breed in arctic areas will vary among species, reduced reproductive success and population declines have been observed in long-distance migrants and species whose reproduction depends on non-climatic cues....

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...
