Environment and Climate Change Canada provides a petroleum product database to be used in oil spill research and response. This database includes the physical properties, chemical composition, and environmental behavior of various types of oils and petroleum products. Original publication:...

The toxicity of pharmaceuticals finasteride (FIN) and melengestrol acetate (MGA) was assessed in freshwater mussels, including acute (48 h) aqueous tests with glochidia from Lampsilis siliquoidea, a sub-chronic (14 days) sediment test with gravid Lampsilis fasciola, chronic (28 days) sediment...

Water quality and ecosystem health surveillance and monitoring data collected to complete assessments of beneficial use impairments of Areas of Concern (AOCs) and to track the effectiveness of remedial measures and confirm restoration of beneficial uses are included in this dataset. AOCs are...

Water quality and suspended sediment monitoring and surveillance data collected from the connecting channels of the Great Lakes to determine baseline water quality status, long term trends and spatial distributions, the effectiveness of management actions, determine compliance with sediment...

Sediment quality data from the Great Lakes collected to determine baseline status, long term trends and spatial distributions, the effectiveness of management actions, determine compliance with sediment quality objectives and identify emerging issues are included in this dataset.

River ice is a known occurrence in cold climate hydrological systems. The annual cycle of formation, growth, decay and clearance of river ice can include low flows and ice jams, as well as mid-winter and spring break-up events. Reports and associated data on river ice occurrence are often limited...

This dataset contains the concentrations of contaminants found in individual and pooled captured Yellow Perch (Perca flavescens) and Shorthead Redhorse (Moxostoma macrolepidotum) from 5 site locations (Stag Island, Lake Huron, Walpole Marsh, Chanel Ecarte, and Chenal Ecarte/Port Lambton) within...

Spanish Harbour was identified as an Area of Concern (AOC) due to degraded water quality and environmental health and was recognized as an Area in Recovery in 1999. As part of the Great Lakes Action Plan, assessments of benthic conditions in Spanish Harbour have been conducted periodically since...

Water quality and ecosystem health data collected in the Great Lakes and priority tributaries to determine baseline water quality status, long term trends and spatial distributions, the effectiveness of management actions, determine compliance with water quality objectives and identify emerging...

Hamilton Harbour is located at the west end of Lake Ontario. It was designated as one of 43 Areas of Concern in 1987 under the GLWQA where 11 beneficial uses of the harbour were deemed impaired. One of the primary recommendations of the Hamilton Harbour Remedial Action Plan was to decrease...

Environment and Climate Change Canada (ECCC) uses satellite remote sensing to monitor lake-wide water quality indicators across Canadian inland waters. Remote sensing provides a cost-effective solution to obtain frequent lake-wide water quality observations in support of lake science and inland...

This dataset contains lake-wide algal bloom indices (extent, intensity, and severity) of Lake of the Woods 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...

This dataset contains lake-wide algal bloom indices (extent, intensity, and severity) of Lake Winnipeg 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 toxicity and bioconcentration of 3 pharmaceuticals (amitriptyline, iopamidol, and sertraline) were examined using multiple life stages (larval, juvenile, and adult) of the unionid mussel Lampsilis siliquoidea. The endpoints examined varied with life stage but included survival, behavior...

Water quality and ecosystem health data are collected in the nearshore zone of the Great Lakes to address the problem of nuisance benthic algae. Monitoring data include physical and chemical water quality data as well as biological data, primarily from Cladophora and dreissenid mussels on the...

Habitat and ecosystem data used to conduct a baseline survey of coastal habitat in the Canadian Great Lakes in support of the Great Lakes Water Quality Agreement (Annex 7, Habitat and Species). The baseline habitat survey integrates various internal and external data sources that are collected or...

Habitat and ecosystem data used to conduct a baseline survey of coastal habitat in Lake Erie, St. Clair River, Lake St. Clair and Detroit River are included in this dataset. The Lake Erie Survey methodology consists of four general steps; 1) delineating the coastal ecosystem into coastal units...

Habitat and ecosystem data used to conduct a baseline survey of coastal habitat in Lake Ontario, Niagara River and the St. Lawrence River (up to the Quebec border) are included in this dataset. The Lake Ontario Survey methodology consists of four general steps; 1) delineating the coastal...

Deltaic Wetlands Biomonitoring Wetland macroinvertebrates, comprising insects, crustaceans, molluscs and worms represent a group of organisms forming a critical food resource for consumer organisms (e.g. fish, birds), that are used widely in environmental monitoring programs to assess both the...

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)...
