Laboratory research was completed to assess the relative toxicity of various short-chain PFAS in adult and juvenile freshwater snails. Tests of various duration (7-28 days) and encompassing three life stages (adults, juveniles, and embryos) were completed with three sulfonic acids (PFSAs):...

Knowledge of the location of Earth’s surface water in time and space is critical to inform policy decisions on environment, wildlife, and human security. Dynamic surface water maps generally represent water occurrence, also referred to as inundation frequency, depicting the percentage of valid...

This study examined the toxicity of aged oil sands tailings waste, and it's affect on eight species of freshwater aquatic organisms: Pimephales promelas (fathead minnow), Oryzias latipes (Japanese medaka), Hyalella azteca, Daphnia magna, Vibrio fischeri, Lampsilis cardium, Ceriodaphnia dubia, and...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Water quality in Canadian rivers indicators provide a measure of the ability of river water across Canada to support...

A station is a site on a river or lake where water quantity (water level and flow) are collected and recorded.

The daily mean is the average of all unit values for a given day.

The Coastal Ice-Ocean Predicton System (CIOPS) provides a 48 hour ocean and ice forecast over different domains (East, West, Salish Sea) four times a day at 1/36° resolution. A pseudo-analysis component is forced at the ocean boundaries by the Regional Ice-Ocean Prediction System (RIOPS)...

The annual maximum and minimum instantaneous data are the maximum and minimum instantaneous values for a given year.

The annual maximum and minimum daily data are the maximum and minimum daily mean values for a given year.

The monthly mean is the average of daily mean values for a given month.

Water quality and ecosystem health data collected using a risk-based monitoring approach to support the Great Lakes Water Quality Agreement are included in this dataset. By conducting regular, systematic measurements of the physical, chemical and biological conditions of the Great Lakes...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The phosphorus loading to lake Erie indicator reports on the total phosphorus loads flowing directly into Lake Erie or from...

Examining the short- and long-term toxicity effects (survival, behaviour and egg production) of Bisphenol A (BPA) and its replacement products (BPS, BPF, BPAF) on the embryo, juvenile and adult life stages of the Ramshorn snail (Planorbella pilsbryi) in 96-hour/7-day/13-day...

This study aimed to address the toxicological effects the type-2 diabetes drug, metformin has on wild fathead minnows (Pimephales promelas). Fathead minnow embryos and adults were exposed to metformin via in-lake mesocosm and their survival, development and growth was assessed. Exposures were...

Zooplankton and phytoplankton were collected during the 56-day metformin in-lake mesocosm exposure conducted Lake 114 at the International Institute for Sustainable Development-Experimental Lakes Area (IILSD-ELA) in northern Ontario, Canada. Samples were collected three times throughout the...

This study will determine the toxic effect the pharmaceutical metformin has on an aquatic environment. Chronic exposures were conducted at Lake 114 located at the International Institute for Sustainable Development-Experimental Lakes Area (IILSD-ELA) in Ontario, Canada. Three concentrations of...

The daily water temperature (°C) dataset is reconstructed using the air2stream model (Toffolon and Piccolroaz 2015) with i) air temperature from ~10 km resolution 1980-2018 Regional Deterministic Reforecast System, version 2.1 (Gasset et al. 2021) and ii) streamflow data from the Water Survey of...
