Atmospheric Contaminant Deposition using Snowpack The data set includes snow samples (metals, water chemistry and polycyclic aromatic hydrocarbons [PAHs]). Data from 2012-2014 snowpack samples collected from ~90-130 sites located varying distances from the major oil sands development area show...

Sediment Transport This data set demonstrates some variation in the data parameters, both in time and with distance along the mainstem Athabasca and two tributaries (Ells and Steepbank Rivers). For the mainstem Athabasca (bulk suspended sediment samples collected via continuous flow...

This dataset contains the concentrations of halogenated phenolic compounds in plasma for the fish species Brown bullhead (Ameiurus nebulosus), from 3 site locations (Peche Island, Grosse Ile, Turkey Creek) within the Detroit River Area of Concern. Halogenated Phenolic Compounds have emerged as...

The epiphytic cyanobacterium Gloeotrichia pisum forms spherical colonies embedded in a gelatinous matrix that is attached to submerged aquatic vegetation. In surveys of two fluvial lakes of the St. Lawrence River conducted in 2006–2007, growth conditions and diazotrophic ability in conjunction...

Wheatley Harbour was designated as one of the 43 Areas of Concern in accordance with Great Lakes Water Quality Agreement (GLWQA). Remedial Action Plan (RAP) is an ongoing collaborative effort implemented by federal, provincial, and local governments as well as industry and public partners. There...

Increased productivity from sewage effluents can enhance species richness locally. Results from a study of Spottail shiners (Notropis hudsonius) in 1999 showed that prevalence and the mean number of myxozoan parasite species per host were higher downstream of the wastewater outflow from the...

Dataset contains laboratory-studied Fathead minnow (Pimephales promelas) survival when exposed to bitumen sediments from the oil sands region of northern Alberta, cut through the McMurray Formation (MF). These are the results of the toxicological exposures, when Fathead minnow embryos were...

The National Pollutant Release Inventory (NPRI) is Canada's public inventory of pollutant releases (to air, water and land), disposals and transfers for recycling. Data from the NPRI are available in a number of format, including datasets and mapping products:...

Mesoscale boundaries have an important influence on mesoscale weather. They can trigger, enhance or inhibit convections and severe weather. They are also indicators of shifts in wind speed and direction, temperature and relative humidity, and can affect air quality and heat indices. Around the...

The data consists of temperature indices based on homogenized daily maximum and minimum temperatures at 338 locations across Canada, and of precipitation indices based on adjusted daily rainfall, daily snowfall and daily precipitation amounts at 463 locations across the country. These indices...

The data consist of homogenized daily maximum, minimum and mean surface air temperatures for more than 330 locations in Canada; adjusted daily rainfall, snowfall and total precipitation for more than 460 locations. The data are given for the entire period of observation. Please refer to the...

The CanRCM4 large ensemble is a 50-member ensemble from 1950-2100 with all historical forcings for the North American Domain. Each ensemble member is driven by a member of the CanESM2 large ensemble (https://open.canada.ca/data/en/dataset/aa7b6823-fd1e-49ff-a6fb-68076a4a477c). The model,...

This dataset was extracted from the 50-member Large-Ensemble Canadian Regional Climate Model (CanRCM4-LE) (Scinocca et al., 2015), North American region 0.44° horizontal grid resolution (NAM-44) model runs. Basin averaged means for nine river basins in Western Canada consisting of three...

In situ observations of snow water equivalent (SWE) from manual snow surveys and automated sensors are made at ~1000 sites across Canada in support of water resource planning for flood control and hydroelectricity production. These data represent an important source of information for research...

The Pan and Parapan American Games are a regional international summer sporting event, staged every 4 years in the year prior to the Summer Olympic and Paralympic Games. The 2015 Games were awarded to Canada on November 6, 2009, by the Pan American Sports Organization. The XVII Pan American...

The Alberta foothills are a primary source of spring runoff into the prairie regions to the east. For this reason, precipitation accumulations in the foothills are vital to prairie water resources. The Foothills Orographic Precipitation Experiment (FOPEX) was initiated in 2002 to study the...

NAV CANADA (NC) provided Environment and Climate Change Canada (ECCC) with automated minutely weather observations from six select AWOS stations (i.e. airport locations) in southern Ontario as an experimental, proof-of-concept program in support of the 2015 Games. The minutely data were at a...

The high spatial and temporal resolution network was comprised of new automated land- and marine-based weather stations, and additional experimental monitoring platforms. Environment and Climate Change Canada (ECCC) designed the Mesonet to monitor weather at the venues, while providing close...

Mesoscale boundaries have an important influence on mesoscale weather. They can trigger, enhance or inhibit convections and severe weather. They are also indicators of shifts in wind speed and direction, temperature and relative humidity, and can affect air quality and heat indices. Around the...

Four ground-based radiometers (ultraviolet radiation instruments) were deployed in the Greater Golden Horseshoe Area in support of the Games. They reported minute-by-minute observations of the ultraviolet (UV) component of sun exposure as defined by the Global Solar UV Index (UVI). The...
