Fisheries and Oceans Canada (DFO) statistical unit areas (also referred to as unit areas) are smaller portions of the Northwest Atlantic Fisheries Organization (NAFO) Subareas, Divisions, and Subdivisions defined in the Convention on Cooperation in the Northwest Atlantic Fisheries (2020). The spatial representation of boundaries defined by NAFO has recently been updated to address inconsistencies and errors in earlier versions, which is available here: https://open.canada.ca/data/dataset/59af1c96-fc8f-4fa0-b398-d65e953eadaa#comment-41855. Unit areas are used by DFO for a variety of purposes including, but not limited to stock assessments, privacy screening of fisheries maps, and statistical analyses.<\/SPAN><\/P> <\/P> Unit areas were originally defined throughout the 1940s and 1950s. Subsequently, several revisions and alternate versions were created by DFO in various regions leading to inconsistencies in spatial extent and naming conventions. These changes have not been formally documented. The datasets often have topological errors such as gaps and overlaps, especially along diagonals and coastlines. In addition, inconsistencies have arisen from conflicting interpretations of the NAFO divisions, where not all land points are defined by coordinates. Therefore, DFO, with input from the Canadian Hydrographic Service (CHS), has created an updated version of the DFO unit areas file to address inconsistencies and errors among previous versions. The recently updated NAFO divisions were used as the basis for an updated DFO unit areas file.<\/SPAN><\/P> <\/P> This version of the DFO must not be used for legal purposes. Legal descriptions of fishing area boundaries can be found in the Atlantic Fisheries Regulations, Maritime Provinces Fishery Regulations, and DFO License Conditions. All datasets were derived using NAD83.<\/SPAN><\/P> <\/P> ********************<\/SPAN><\/P> <\/P> Les zones unitaires statistiques de Pêches et Océans Canada (MPO) [également connues sous le nom de « zones unitaires »] sont de petites portions des sous-zones, divisions et subdivisions de l\u2019Organisation des pêches de l\u2019Atlantique Nord-Ouest (OPANO) définies dans la Convention sur la coopération dans les pêches de l\u2019Atlantique du nord-ouest (2020). La représentation spatiale des frontières définies par l\u2019OPANO a récemment été mise à jour afin de corriger les incohérences et les erreurs présentes dans les versions antérieures. Cette mise à jour est disponible à l\u2019adresse suivante : https://open.canada.ca/data/fr/dataset/59af1c96-fc8f-4fa0-b398-d65e953eadaa. Les zones unitaires sont utilisées par le MPO à des fins diverses, comme l\u2019évaluation des stocks, la vérification de la confidentialité des cartes des pêches et les analyses statistiques.<\/SPAN><\/P> <\/P> Les zones unitaires ont été définies dans les années 1940 et 1950. Par la suite, plusieurs révisions et nouvelles versions ont été créées par le MPO dans diverses régions, ce qui a entraîné des incohérences quant à l\u2019étendue spatiale et aux conventions d\u2019appellation. Ces modifications n\u2019ont fait l\u2019objet d\u2019aucune documentation officielle. Les ensembles de données comportent souvent des erreurs topologiques, comme des lacunes et des chevauchements, notamment le long des côtes et des diagonales. En outre, des incohérences sont nées d\u2019interprétations contradictoires concernant les divisions de l\u2019OPANO, où tous les points terrestres ne sont pas toujours définis par des coordonnées. Ainsi, le MPO, avec l\u2019aide du Service hydrographique du Canada (SHC), a créé une version actualisée du fichier des zones unitaires du MPO afin de corriger les incohérences et les erreurs présentes dans les versions précédentes. Les divisions de l\u2019OPANO récemment mises à jour ont servi de base à la mise à jour du fichier des zones unitaires du MPO.<\/SPAN><\/P> <\/P> Cette version des zones unitaires du MPO n\u2019est pas destinée à être utilisée à des fins juridiques. Les descriptions juridiques relatives aux limites des zones de pêche figurent dans le Règlement de pêche de l\u2019Atlantique, le Règlement de pêche des provinces maritimes et les conditions de permis du MPO. Tous les ensembles de données ont été dérivés en utilisant le système NAD83.<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>",
