Abstract

This resource documents a dataset of infauna occurrences collected from 2021 to 2023 during the Canadian Beaufort Sea Marine Ecosystem Assessment (CBS-MEA) conducted by the Department of Fisheries and Oceans (DFO). This scientific program focuses on the integration of oceanography, food web linkages, physical-biological couplings, and spatial and interannual variabilities.The program also aims to expand the baseline coverage of species diversity, abundances, and habitat associations in previously unstudied areas of the Beaufort Sea and Western Canadian Archipelago. Endobenthic invertebrates were identified from catches collected with a 50 x 50 cm box corer. //Cette ressource documente un jeu de données sur les occurrences d'endofaune collectées de 2021 à 2023 lors de l'évaluation environnementale marine de la mer de Beaufort canadienne (CBS-MEA) menée par Pêches et Océans Canada (MPO). Le programme CBS-MEA se concentre sur l'intégration de l'océanographie, des liens dans le réseau alimentaire, des couplages physico-biologiques et des variabilités spatiales et interannuelles. Le programme vise également à élargir la couverture de référence de la diversité des espèces, des abondances et des associations avec les habitats dans des zones de la mer de Beaufort et de l'archipel canadien de l'Ouest précédemment non étudiées. Les invertébrés endobenthiques ont été identifiés à partir des prises collectées par un carottier à boîte de 50 x 50 cm.
