This dataset contains annual algal bloom indices (duration, extent, intensity, severity) summary statistics (maximum, mean) over the June through October monitoring period for Lake Winnipeg. These data are derived from satellite remote sensing algorithms using European Space Agency's (ESA's)...

This dataset contains lake-wide algal bloom indices (extent, intensity, and severity) of Lake Erie on a daily basis over the June through October monitoring season. These data are derived from satellite remote sensing algorithms using European Space Agency's (ESA's) MEdium Resolution Imaging...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Greenhouse gas emissions from large facilities indicator reports total emissions of large greenhouse gas emitters in...

A database of verified tornado occurrences across Canada has been created covering the 30-year period from 1980 to 2009. The tornado data have undergone a number of quality control checks and represent the most current knowledge of past tornado events over the period. However, updates may be made...

The Richelieu River, Quebec, is a highly-regulated waterway subject to numerous anthropogenic influences from municipal effluents and agricultural activities. Parasite communities in 234 spottail shiners (Notropis hudsonius) were examined from 4 localities in late spring 2003 and 2004. Parasite...

In this study, seven non‐specific biomarkers were compared in Spottail Shiners (Notropis hudsonius Clinton) from localities receiving urban and industrial effluents and relatively clean localities in the St Lawrence River, Canada. Pigmented macrophages are involved in a variety of functions...

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...

Lake Simcoe is located North of Toronto in Ontario, Canada and is a premier destination for tourists generating $200 million in revenue annually. Lake Simcoe is the 4th largest lake in Ontario with a surface area of 722 square kilometers and a watershed of 2900 square kilometers. Lake Simcoe has...

Environment and Climate Change Canada’s monitoring program for species at risk, rare and difficult-to-monitor species uses targeted sampling designs to assess the population status and trend of species that are not readily sampled by other programs. A formal analysis was used to prioritize...

Parasite communities were examined in Johnny Darters (Etheostoma nigrum) collected from five localities in the St. Lawrence River in southwestern Quebec: two reference localities, one polluted locality upstream of the Island of Montreal and downstream of industrial and agricultural activity, and...
