Significant parameters for different species with status under the Species at Risk Act (SARA)
Layers that present various important parameters such as inventories, presence, sightings, distribution, relative occurrence or catch rates, critical habitat, breeding and feeding areas, potential spawning and haul-out sites for the different species with status under the Species at Risk Act (SARA).The act classifies those species as being either extirpated, endangered, threatened, or of special concern. Under SARA, Fisheries and Oceans Canada must produce recovery strategies and action plans for aquatic species listed as endangered or threatened. The act is part of Canada’s strategy to protect hundreds of wild plants and animal species from becoming extinct, and to help in their recovery.The different species represented by the layers are the following:1. American shad (Alosa sapidissima)2. Atlantic sturgeon (Acipenser oxyrinchus)3. Atlantic wolffish (Anarhichas lupus)4. Beluga whale (Delphinapterus leucas)5. Blue whale (Balaenoptera musculus)6. Copper redhorse (Moxostoma hubbsi)7. Eelgrass (Zostera marina)8. Grey seal (Halichoerus grypus)9. Harbor seal (Phoca vitulina)10. Humpback whale (Megaptera novaeangliae)11. Lake sturgeon (Acipenser fulvescens)12. Lumpfish (Cyclopterus lumpus)13. Northern wolffish (Anarhichas denticulatus)14. Rainbow smelt (Osmerus mordax)15. Sea pens (Pennatulacea)16. Seaweed17. Smooth skate (Malacoraja senta)18. Sponges19. Spotted wolffish (Anarhichas minor)20. Striped bass (Morone saxatilis)21. Thorny skate (Amblyraja radiata)22. Winter skate (Leucoraja ocellata)

Occurrence and percent cover of the colonial invasive tunicate Didemnum vexillum from near-seafloor drift transect video imagery and high-resolution digital still images in the western Bay of Fundy
Funded under DFO's Marine Conservation Targets Program, this optical imagery benthic survey documents the occurrence and estimated percent cover of the invasive colonial tunicate, Didemnum vexillum in seven drift-camera transects in the 'Head Harbour/West Isles Archipelago/The Passages' Ecologically and Biologically Significant Area (ESBA, ~113km2) in the western Bay of Fundy, New Brunswick, Canada. Occurrence data was derived from the use of high-resolution still images (n=386) taken periodically throughout each transect, and simultaneous continuous high-definition video. Video was divided into 20-second segments (here, we report the start and end location of each segment within a transect) and when D. vexillum was present in a video segment, frequency of occurrence was classified as common (continuous coverage/patches throughout the video segment), occasional (individual colonies of various sizes encountered >5 times throughout the video segment), or rare (small, isolated colonies encountered ≤5 times throughout the video segment). A video segment was deemed unusable and removed from the dataset if there was too much turbidity, or if the camera position was too high off-bottom to reliably image the seafloor. For still images, when D. vexillum was observed in an image, colony percent cover was categorized as >50%, 26-50%, 6-25%, or ≤5% of the images field of view (FOV). Distance travelled and distance between still images (m) was calculated using ArcGIS tools. FOV was estimated by measuring the length and width of a subset of still images and video frame grabs in ImageJ2, using 10-cm lasers for scale. FOV was standardized for each reported altitude, and area sampled (m2) along a continuous video segment was estimated by multiplying the average FOV by the distance travelled in that segment. D. vexillum was found in 44% of the area sampled at depths from 34 to 118m, deeper than previous reports globally of ~80m.Cite this data as: Teed LL, Goodwin C, Lawton P, Lacoursière-Roussel A, Dinning KM (2024) Multiple perspectives on the emergence of the invasive colonial tunicate Didemnum vexillum Kott, 2002 in the western Bay of Fundy, Atlantic Canada.

Education - Authorities Francophone
This is an approximated visualization of the School Authority Francophone information that is currently available on the Alberta Education public website (https://education.alberta.ca/boundary-maps/school-jurisdiction-maps/everyone/view-and-print-maps). The information has been informed by Ministerial Orders and is presented in a mapping format.

Polygons of inland water bodies of the Magdalen Islands Lagoons Marine Refuge
This cartographic dataset represents a geomorphological update of the boundaries of the five inland water bodies that form the Magdalen Islands Marine Refuge. It was produced by Fisheries and Oceans Canada (DFO) as part of its marine refuge characterization work.The data used comes from the August 15, 2022 version of the Quebec maritime Geospatial Database of Coastal Ecosystems (GDB), developed from various sources including satellite and airborne images from 2019 (Jobin et al. 2021; Provencher-Nolet et al. 2024). The boundaries of the inland water bodies were defined according to the upper high tide line, which represents the maximum extent of the water during the highest tides.The final product is a polygonal shapefile representing the five inland water bodies of the marine refuge as well as the terrestrial areas of the archipelago. The data are projected in NAD83 / MTM zone 4.For more information on the method used to generate this layer from the GDB, see Grégoire et al. (2026). The method used to create the source geospatial data is described in Jobin et al. (2021) and Provencher-Nolet et al. (2024).
Paleozoic Structure Map
These structure, isopach and zero edge files are part of a series of stratigraphic framework maps for the Saskatchewan Phanerozoic Fluids and Petroleum Systems (SPFPS) project.The series of stratigraphic framework maps for the Saskatchewan Phanerozoic Fluids and Petroleum Systems (SPFPS) project have been produced using 2 km equi-spaced modified grids generated from Golden Software’s Surfer 9 kriging algorithm. The dataset used to produce each of the maps in this series was created using data from several projects completed by the Ministry (Christopher, 2003; Saskatchewan Industry and Resources et al., 2004; Kreis et al., 2004; Marsh and Heinemann, 2006; Saskatchewan Ministry of Energy and Resources et al., 2007; Heinemann and Marsh, 2009); these data were validated and edited as required to facilitate correlations between the various regional projects. In addition, to minimize edge effects during contouring, the senior author also generated stratigraphic data from wells in adjacent jurisdictions.
