On a délimité les concentrations de plumes de mer, de petites et grandes gorgones, et d'éponges sur la côte est du Canada par le biais de l'analyse spatiale des données sur les prises accessoires recueillies lors des relevés effectués par navire de recherche. L'analyse a adopté une approche de l'Organisation des pêches de l'Atlantique Nord-Ouest (OPANO) dans la zone de réglementation du Bonnet Flamand et le sud-est des Grands Bancs. On a eu recours à une analyse du noyau de densité a fin de délimiter les hautes concentrations. De telles analyses ont été réalisées pour chacune des cinq zones biogéographiques de l'est du Canada. Les plus grandes colonies de plumes de mer ont été découvertes dans le chenal Laurentien qui coupe le golfe du Saint-Laurent, alors que les grands regroupements de gorgones ont été trouvés dans l'Arctique de l'Est et le nord de la pente continentale du Labrador. De grosses éponges en boule de plusieurs espèces de Geodia se trouvaient le long des pentes continentales au nord des Grands Bancs, tandis qu'on a identifié sur le Plateau néo-écossais une seule population de grosses éponges en forme de tonneau de l'espèce Vazella pourtalesi. On fournit la latitude et la longitude marquant les positions de tous les traits qui forment ces colonies et d'autres concentrations denses, ainsi que les positions de tous les traits de chalut qui ont permis de remonter à la surface du corail noir, un taxon que l'on ne retrouve pas enregroupement, qui est d’une grande longévité et vulnérable à la pression de la pêche.

Critical habitat polygons and lines were assembled by SARA regional biologists and recovery teams. They are designed to support the protection and recovery of species listed as Endangered or Threatened under the Species at Risk Act. They are also described and displayed in species’ Recovery Documents and Action Plans. For the complete extent and view of a species' Critical Habitat both Lines and Polygons must be displayed simultaneously. Please note: there are different types of Critical Habitat descriptors. This dataset may use a “bounding box” or "parcel" approach that delineates an area or extent in which the species may be found. Descriptors (such as bounding box coordinates are not included in this dataset).

WMS med FOT data der trækkes fra en kopi af FOT2007. Data opdateres hver nat. Tjenesten er en vektorbaseret WMS, dvs. renderingen af kortudsnittet foretages on-the-fly af serveren ud fra rå data i databasen, hvilket har betydning for performance. Tjenesten indeholder kun gældende FOT objekter, disse er af performancemæssige hensyn samlet i 2 lag: basis (alle FOT objekter med undtagelse af de punktobjekter der kun vise i deltaljelaget) og detalje (punktobjekter fra objektklasserne Teknik og Natur). Kontakt FOTDanmark for nærmere information om denne tjeneste.

The compilation represents publicly available reports of geochronological information for Canada. This includes federal, provincial and territorial government publications and reports, university theses, books and journals, Current coverage is limited to those areas that have been the target of recent past compilation efforts, with other areas and updates being included as they become ready. Users should be aware that the compilation may not include all available data for a given area. Every effort is made to report the ages without reinterpreting the original authors’ intent. However, care has also been taken to highlight the salient features of the data by which the end-user can make initial judgment on the data robustness. Users are cautioned that because of space limitations and the necessary summarization of often complex datasets, that the original publication should be consulted to verify age interpretations and their rationale. Data may be extracted by the user in data in either tab-delimited text or WMS formats. - Cette compilation est composée d'information géochronologique pour le Canada provenant de références bibliographiques. La base de connaissances inclus des publications et rapports du gouvernement fédéral, des gouvernements provinciaux et territoriaux, de thèses universitaires, livres et journaux scientifiques. L'étendue de la couverture est limitée aux régions qui ont été la cible de compilations récentes. D'autres régions de compilation seront incluses dès qu'elles seront disponibles. Il est à noter que la compilation de données peut ne pas contenir toutes les données disponibles pour une région spécifique. Tous les efforts ont été faits pour rapporter les âges sans réinterpréter l'intention originale de l'auteur. Toutefois, une attention particulière à été porté sur les données de façon à mettre en évidence les points saillants pour permettre à l'utilisateur de porter un jugement initial sur la robustesse des données. Dû à l'espace limitée et à la nécessité de résumé des données complexes, les utilisateurs sont avertis que la référence originale devrait être consultée pour vérifier l'interprétation originale et son fondement. Les données peuvent être extraites en format texte délimité par tabulations ou en format WMS.

Flood extent polygons representing past floods throughout Canada as monitored by Natural Resources Canada using satellite imagery for emergency response. In response to large flood events, Natural Resources Canada, for the provision of emergency geomatics services (NRCan), may be activated by Canada’s emergency management protocols. This item contains past years archive of the flood products generated by NRCan emergency geomatics services. The flood products are generated and validated on a best effort basis. Various factors may affect the quality of the flood polygons. Those factors include but are not limited to: sensor type, image resolution, cloud coverage or limits to the flood polygon extraction method. In this layer, a symbology is applied to the flood polygons based on the underlying land use classification, when available, or is simply unclassified and shows the gross flood extent otherwise. Filter on date and Area of Interest (AOI) to view specific products. Time-enabled on Date UTC field. ".zip" file packages that contain the shapefile, PDF map, and ".kmz" of individual product items are available through the FTP links listed in the Package URL field. Disclaimer: Emergency response authorities are the primary users of these satellite-derived open water flood extent map products. These products are generated to provide analysis and emergency response situational awareness and to facilitate decision-making during major flood events. The open water flood extent products are generated rapidly and limited time is available for editing and validation. The flood products reflect the open water flood conditions at the date/time of acquisition. While efforts are made to produce high quality products, near-real time products may contain errors due to the limited time available for vector editing and validation. Please note that current algorithms do not map flooded areas under the forest canopy and are not optimized for urban flood mapping.
