Fisheries and Oceans Canada (DFO) selected the Manicouagan Peninsula area as a site of interest for the possible establishment of a Marine Protected Area (MPA) in 1998. With this in mind, DFO conducted surveys to assess benthic biodiversity between 2006 and 2008. During the various campaigns, more than a hundred stations were sampled using various tools to target epibenthic and endobenthic species. Various tools were used during the three years of sampling, including an SM (Smith-McIntyre) grab with an area of 0.1 m² and a height of 20 cm, an IKU-type grab with a surface area of 1.5 m² and a height of 50 cm, and a hydraulic dredge measuring 1.36 m wide and 0.66 m high with a net mesh size of 2.3 cm. As the dredge clogged fairly quickly, small organisms were collected in abundance. In 2006 and 2007, a camera mounted on a sled pulled by a boat along transects of varying lengths depending on the sampling campaign collected images (3,008 x 2,000 pixels) every 10 seconds, representing a seabed area of 40 x 40 cm. The data are presented in Darwin Core format in the file “donnees_manicouagan_data” The available data include taxonomic identifications of samples (individuals collected or…
