Groundwater wells were installed in the Turkey Lakes Watershed basin in the early 1980’s. These test wells were installed in eight sub-basins of the watershed and range in depth from 0.5 to 9.7 metres. They are located on a variety of terrain throughout. The water chemistry has been sampled at...

Communities in east Hudson Bay and James Bay are concerned about ecosystem changes observed in recent decades, particularly related to sea-ice conditions, and also about potential impacts of contaminants from long-range atmospheric transport and regional human activities. The Arctic Eider...

One component of this initiative aims to improve current understanding of nutrient dynamics and cyanobacterial and harmful bloom (cHAB) occurrences on Lake of the Woods. Research will focus on investigating the sources of nutrients and additional mechanisms influencing cHAB development and...

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...

This dataset contains the fish health metrics (length, weight, gonad size, etc.) for Shorthead redhorse (Moxostoma macrolepidotum) and Golden redhorse (Moxostoma erythrurum) collected from two site locations (Stag Island, and Lake Huron) within the St. Clair River Area of Concern for 2003....

This dataset contains the fish health metrics (length, weight, gonad size, etc.) for Brown bullhead (Ameiurus nebulosus) collected from three site locations (Randal Reef, Carol's Point and Jordan Harbour) within the Hamilton Harbour Area of Concern. Supplemental Information: Funding for this...

The delivery of perfluoroalkyl substances (PFAS) from snowpacks into Lake Hazen, located on Ellesmere Island (Nunavut, Canada) indicates that annual atmospheric deposition is a major source of PFAS that undergo complex cycling in the High Arctic. Perfluoroalkyl carboxylic acids (PFCA) in...

These data contain the results of chronic toxicity tests with perfluorooctanoic acid (PFOA) to Hyalella azteca and Fathead minnow (Pimephales promelas) to set a PFOA freshwater target concentration for cleanup of industrial sites.

Since 1988, the governments of Canada and Quebec have been working together to conserve, restore, protect and develop the St. Lawrence River under the St. Lawrence Action Plan (SLAP). One of the projects identified under the theme of biodiversity conservation is the development of an integrated...

Long-term freshwater quality monitoring data for one site in the North Shore - Gaspé basin for the past 15 years or longer for nutrients, metals, major ions, and other physical-chemical variables are included in this dataset. Monitoring is conducted by Environment and Climate Change Canada (ECCC)...

Long-term freshwater quality monitoring data for sites in the Maritime Coastal basin for the past 15 years or longer for nutrients, metals, major ions, and other physical-chemical variables are included in this dataset. Monitoring is conducted by Environment and Climate Change Canada (ECCC) and...

Long-term freshwater quality monitoring data for sites in Newfoundland and Labrador (NL) for the past 15 years or longer for nutrients, metals, major ions, and other physical-chemical variables are included in this dataset. Monitoring is conducted by Parks Canada. Environment and Climate Change...

Long-term freshwater quality monitoring data for over 12 sites in the Saint John and St. Croix River basins for the past 15 years or longer for nutrients, metals, major ions, and other physical-chemical variables are included in this dataset. Monitoring is conducted by Environment and Climate...

This dataset contains the stable nitrogen (δ15N), carbon (δ13C), oxygen (δ18O), and hydrogen (δ2H) isotope data from 1123 samples of underfur hair of adult polar bears (Ursus maritimus) sampled between 1992 to 2017 from subpopulation boundaries (zone) in the Canadian Arctic and sub-Arctic....

Hamilton Harbour is a 2200 ha embayment 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...

Coastal wetlands are valued for their diversity of wildlife, habitats, and functions. The Canadian Wildlife Service (CWS) conducted vegetation and elevation surveys between 2009 and 2019, and bathymetric and light attenuation surveys between 2018 and 2019 in coastal wetlands across the Canadian...

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...
