The main objective of this sampling program was to assess the effects of the spill on the toxicity of surface water collected during the spill by comparing them with the results of water collected prior to the discharge.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

This thematic layer represents the characterization of the hardness of surface water in Quebec. The hardness is presented according to the medians calculated from the concentrations of calcium and magnesium ions in seven classes. Water hardness influences the toxicity of certain metals, including barium, beryllium, cadmium, chromium, copper, manganese, nickel, nickel, lead, and zinc. Surface water quality criteria are determined according to the hardness of the receiving watercourse. These criteria are used to make judgments about surface water quality and are the basis for groundwater criteria used to assess the quality of groundwater that recurs as surface water. Finally, they are the key element in calculating environmental discharge objectives (EORs) used to assess the quality of wastewater discharges to the aquatic environment. For a discharge that occurs on an annual basis, the median hardness of the receiving water body is generally used to calculate water quality criteria for aquatic life.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The Riparian Quality Index (IQBR) is used to assess the ecological condition of the shoreline environment. It is built from nine components that have been weighted according to their potential to perform ecological functions in terms of the protection of aquatic ecosystems.Data on shoreline quality come from benthos monitoring stations sampled between 2003 and 2023.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

This dataset is used to: * assess biodiversity levels * define seed zones * map ecosystem types * set targets for the identification of natural heritage systems

Feature point layer showing locations of distributors participating in the Naloxone Take Home Program in Manitoba.This feature point layer shows the locations of distributors participating in the Naloxone Take Home Program in Manitoba. Naloxone is a drug that temporarily reverses overdose (toxicity) caused by opioid drugs (such as fentanyl, heroin, morphine, hydromorphone). Free take-home naloxone kits are available to members of the public who are at risk of opioid overdose (toxicity), and family or friends who may witness opioid toxicity. For more information see Manitoba Health. This feature layer is used in the Naloxone Distributors Map - Take Home Program and Naloxone Finder - Take Home Program application.

Monitoring of Unit 2 redfish by Fisheries and Oceans Canada (DFO) ceased in 2002. Since then, the Atlantic Groundfish Council (AGC, formerly the Groundfish Enterprise Allocation Council [GEAC]) has funded surveys approximately every two years in the area, in collaboration with DFO. Over the years, various vessels and gear types have been used. In 2024, a comparative survey was conducted using the CCGS John Cabot and a fishing industry vessel (the Léry Charles) to develop conversion factors that allow data from the 2020, 2022, and 2024 Unit 2 redfish surveys to be standardized to CCGS John Cabot equivalents. The survey covered the waters off southwestern Newfoundland and eastern Cape Breton, corresponding to redfish management Unit 2, which includes NAFO subdivisions 3Pn, 3Ps, 4Vn, 4Vs, and 4W. Here, data collected aboard the CCGS John Cabot are presented. Objectives• Assess the abundance and condition of groundfish and invertebrates• Assess environmental conditions• Inventory the biodiversity of benthic and demersal megafauna• Monitor the pelagic ecosystem• Collect samples for various research projectsData The CCGS John Cabot employed a four-sided modified Campelen 1800 shrimp trawl, fitted with a Rockhopper ("bicycle") footgear. The trawl extension and codend were lined with 12.7 mm knotless nylon mesh. Standard trawl tows were 15 minutes in duration, timed from bottom contact, with a target towing speed of 3 knots.For each fishing tow, the catch is sorted and weighed by taxa; individuals are then counted and biological data are collected on a subsample. For fish, crab and squid, size and weight are measured by individual and, for some species, sex, gonad maturity, and the weight of certain organs (stomach, liver, gonads) are also evaluated. The soft rays of the anal fin are counted for redfish, and the otoliths are sampled for several species such as Atlantic cod, Atlantic halibut, and Greenland halibut. Roughly 2-kg of shrimp are sorted and weighed by species. The other invertebrates are counted (no individual measurements) and photographed.The biological data are divided into 4 files: a “Stations” file containing set information, a “Catches” file containing catches per set for fish taxa, a “Carbio” file containing biological and morphometric measurements per individual and a “Shrimps” file containing information on shrimp catches. The columns source_info, no_survey, nbpc and set_number serve as a common key linking the four datasets.It is important to note that this is raw data. Only sets considered successful are retained. In each set, all species are kept, with a few exceptions. Data is available from 1997-2022 but please contact the data management team (gddaiss-dmsaisb@dfo-mpo.gc.ca) for access and further details. For any other information please also contact the data management team.

This data contains location information for 1 of Ontario’s snow monitoring networks: * Surface Water Monitoring Centre (SWMC) Snow course data is collected by: * conservation authorities * Ontario Power Generation * Ministry of Natural Resources (MNR) districts Data is collected twice a month from November 15 until May 15. The Surface Water Monitoring Centre uses this data to assess: * current snow cover * frozen ground conditions * snowpack * potential snowmelt * contributions to streamflow The snow data is located in a corporate water and climate database. This data helps MNR and conservation authorities assess the potential for flood at the local and provincial scale.

Prior to January 1, 2008, fishing divisions were administrative units to manage, monitor, assess and regulate recreational fisheries. Each zone was based on angler usage and ecological/geographic patterns. Refer to [Fisheries Management Zone for boundaries after 2008](/dataset/fisheries-management-zone).

Bathymetry line data was collected to assess fish habitat in Ontario. Spot depths (bathymetry points) were used to measure the depth contours, which function like isobars to show lines of constant depth. Their density and positional accuracies vary depending on the survey style and parameters. This data should never be used for navigation.
