Flood markers
The Ministry of Public Security (MSP) supports the development of knowledge of flood risks. Flood markers make it possible to illustrate the water level reached during a very major flood and thus to raise public awareness of the risks associated with it while maintaining this awareness of risk in the collective memory. __What is a flood marker? __A flood marker is a physical mark (15 cm in diameter for the standard) testifying to the maximum level reached by a watercourse during a very significant flood on a given date. The flood marker is usually located at a permanent location and is easily visible to everyone, for example on the wall of a building or on a dedicated pole.__Point dataset “Flood markers” __ The “Flood reference” data set contains, for each marker, the location, the date of the reference flood and the maximum water level reached. The list of all attributes is provided in the dataset description sheet (Additional Information section).Despite the quality of the work carried out, the Ministry of Public Security cannot guarantee the absence of errors in the data.__Related datasets__ The “Water levels during a flood” dataset produced by the Ministry of Public Security also contains maximum water levels reached during a flood. The link to this dataset is provided in the _Documentation_ section.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

Manitoba Provincial Boundary
Feature layer of the Manitoba provincial boundary.A feature layer of Manitoba's provincial boundaries:Manitoba/Ontario boundary, Manitoba/Saskatchewan boundary, Manitoba/Nunavut boundary, International boundary. Excluding the International Boundary, the graphical data was computed from original boundary survey measurements published in respective official boundary commission reports using least squares adjustment software "Manor". The adjustments were constrained to known NAD83 [nmip94 adj.] federal/provincial boundary marker positions. For the International Boundary, the graphics were created by converting the official published NAD27 marker positions for the boundary into NAD83 using datum conversion software NTv2 and interconnecting the plotted marker positions with straight lines using CARIS map software. The purpose is to provide end users with a digital map of Manitoba's boundaries. This data layer is suitable for most medium and small scale digital map applications as well as GIS georeferencing in general. This Manitoba provincial boundary was originally published on January 12, 2004. It was uploaded to Manitoba Maps as a feature layer on December 15, 2016. Use Constraints: The Hudson Bay shoreline for this product was taken from 1:500,000 scale digital mapping and is intended for generalized small scale mapping of this portion of the provincial boundary. Estimated accuracy if plus or minus 125m. Fields Included: FID: Sequential unique whole numbers that are automatically generated, AREA: GIS area in square-metres calculated in the NAD83 Universal Transverse Mercator Zone 14 coordinate system, PERIMETER: GIS perimeter in metres calculated in the NAD83 Universal Transverse Mercator Zone 14 coordinate system, NAME: province name

Development of a coastal species characterization approach using environmental DNA (eDNA) using the marker COI
Species characterization by environmental DNA (eDNA) is a method that allows the use of DNA released into the environment by organisms from various sources (secretions, faeces, gametes, tissues, etc.). It is a complementary tool to standard sampling methods for the identification of biodiversity. This project provides a list of invertebrates species whose DNA has been detected in water samples collected at 2018 using the marker COI.The surveys were carried out in the summer of 2018 from August 11 to 14, between Forestville and Godbout (Haute-Côte-Nord). Sampling was carried out between 9-52 meters depth in 40 stations with one sample par station. Two liters of water were filtered through a 1.2 µm fiberglass filter. DNA extractions were performed with the DNeasy Blood and Tissue extraction kit (Qiagen). Negative field, extraction and PCR controls were added at the different stages of the protocol. Libraries at the COI locus were prepared by Genome Quebec and sequenced on an Illumina MiSeq PE250 system. The bioinformatics analysis of the sequences obtained was carried out using an in-house analysis pipeline as reported in Bourret et al. 2022. A first step made it possible to obtain a molecular operational taxonomic unit table (MOTU) using the cutadapt software for the removal of the adapters and the DADA2 R package for the filtration, fusion, chimera removal and data compilation. The MOTUs table was subsequently corrected by taking into account the negative controls, where the number of observations in the latter was removed from the linked samples. Singleton MOTUs have also been removed. Finally, the taxonomic assignments were carried out on the MOTUs using the IDTAXA classifier (present in the DECIPHIER R package) using a training set trained on the COI reference bank for Golf St-Laurent (GSL-rl v1.0, https://github.com/GenomicsMLI-DFO/MLI_GSL-rl) and a threshold of 40. Detections with an “Unreliable due to gaps” category were reported at the genus level only.The file provided includes generic activity information, including site, station name, date, marker type, assignment types used for taxa identification, and a list of taxa or species. The list of taxa has been verified by a biodiversity expert from the Maurice-Lamontagne Institute.This project was funded by Fisheries and Oceans Canada's Coastal Environmental Baseline Data Program under the Oceans Protection Plan. This initiative aims to acquire baseline environmental data that contributes to the characterization of significant coastal areas and supports evidence-based assessments and management decisions to preserve marine ecosystems.Data are also available on SLGO platform : https://doi.org/10.26071/ogsl-cd4c205b-f63b
Development of a coastal species characterization approach using environmental DNA (eDNA) using the marker Mifish (12S)
Species characterization by environmental DNA (eDNA) is a method that allows the use of DNA released into the environment by organisms from various sources (secretions, faeces, gametes, tissues, etc.). It is a complementary tool to standard sampling methods for the identification of biodiversity. This project provides a list of fish and marine mammal species whose DNA has been detected in water samples collected between 2019 and 2021 using the mitochondrial marker MiFish (12S).The surveys were carried out in the summer of 2019 (July 14-18) and (July 30 - August 5), in the fall of 2020 (October 27-28) and in the summer-fall of 2021 (May 31 - June 3 ) and (August 24-25) between Forestville and Godbout (Haute-Côte-Nord). Sampling was carried out between 1-50 meters depth in 91 stations, with 1 to 3 replicates per station. Two liters of water were filtered through a 1.2 µm fiberglass filter. DNA extractions were performed with the DNeasy Blood and Tissues or PowerWater extraction kit (Qiagen). Negative field, extraction and PCR controls were added at the different stages of the protocol. The libraries were prepared either by Génome Québec (2019, 2020) or by the Genomics Laboratory of the Maurice-Lamontagne Institute (2021), then sequenced on a NovaSeq 4000 PE250 system by Génome Québec. The bioinformatics analysis of the sequences obtained was carried out using an analysis pipeline developed in the genomics laboratory. A first step made it possible to obtain a table of molecular operational taxonomic units (MOTU) using the cutadapt software for the removal of the adapters and the R package DADA2 for the filtration, the fusion, removal of chimeras and compilation of data. The MOTUs table was then corrected using the R package metabaR to eliminate the tag-jumping and take contaminants into consideration. Samples showing a strong presence of contaminating MOTUs were removed from the dataset. The MOTUs were also filtered to remove all remaining adapter sequences and also retain only those of the expected size (around 170 bp). Finally, taxonomic assignments were made on the MOTUs using the BLAST+ program and the NCBI-nt database. Taxonomic levels (species, genus or family) were assigned using a best match method (Top hit), with a threshold of 95%. Only assignments at the level of fish and marine mammals were considered, and the taxa detected were compared to a list of regional species, and corrected if necessary. The species detections of the different replicas have been combined.The file provided includes generic activity information, including site, station name, date, marker type, assignment types used for taxa identification, and a list of taxa or species. The list of taxa has been verified by a biodiversity expert from the Maurice-Lamontagne Institute.This project was funded by Fisheries and Oceans Canada's Coastal Environmental Baseline Data Program under the Oceans Protection Plan. This initiative aims to acquire baseline environmental data that contributes to the characterization of significant coastal areas and supports evidence-based assessments and management decisions to preserve marine ecosystems.Data were also published on SLGO platform : https://doi.org/10.26071/ogsl-2239bca5-c24a

British Columbia Coastal Anchor Marks
The marks left in the seabed by the commercial anchoring process can be seen as linear features in high-resolution multibeam bathymetry data. These features have been digitized to polylines for individual marks and polygons for anchor scour zones for British Columbia's (BC) commercial anchorages. They are made available via the Federal Geospatial Platform (FGP) for use in a Geographical Information System (GIS). This feature dataset is complete for published BC commercial anchorages and the multibeam bathymetry data available in 2021. It does not represent features produced since the collection of each multibeam bathymetry survey nor any features infilled since. The data are intended to be used for scientific research to better understand the cumulative impacts to the seabed from commercial anchoring at a 1:5000 scale or greater.
