Abstract

fetched live from OpenAlex

This dataset derives from a series of beam trawl tows conducted during several research surveys in coastal areas of the St. Lawrence Estuary, between Portneuf-sur-Mer and Pointe-des-Monts, and between June and October of 2019, 2020 and 2021. It contains catch data for fish and invertebrates (occurrence and catch weights by species), in trawl tows conducted at depths ranging from 10 to 50 meters. The research surveys were undertaken by the Department of Fisheries and Oceans Canada as part of the baseline program of the Ocean Protection Plan. This initiative aimed to acquire environmental baseline data contributing to the characterization of important coastal areas and in support of evidence-based assessments and management decision-making for preserving marine ecosystems. Data acquired during the research surveys additionally included: 1) occurrence data on epibenthic invertebrates and submerged aquatic vegetation in photo samples from a drop camera system, 2) occurrence data on fish and invertebrate taxa in video samples collected using a baited underwater video system (BUV), 3) substrate classification based on drop camera photo samples, 4) oceanographic measurements of the water column from Seabird 19plus V2 profiling CTD (conductivity, temperature, depth, photosynthetic active radiation, pH, dissolved oxygen), 5) nutrients (NO2, NO3, NH4, PO4, SiO3) and dissolve organic carbon (DOC) concentrations, and 6) current speed and direction from tilt meters. The first two items are available as independent data on the OBIS portal. To obtain data from items 3-6 and/or biological data collected on fish and invertebrate taxa, please contact David Lévesque or Marie-Julie Roux. // Ce jeu de données provient de captures réalisées dans une série de traits de chalut à perche effectués lors de relevés en milieux côtiers sur la rive nord de l'estuaire du Saint-Laurent, entre Portneuf-sur-Mer et Pointe-des-Monts, et entre juin et octobre de 2019, 2020 et 2021. Il contient les données de capture de poissons et invertébrés (occurrence et poids de capture par espèce) pour des traits de chalut effectués à des profondeurs allant de 10 à 50 mètres. Les relevés scientifiques ont été réalisés dans le cadre du Programme sur les données environnementales côtières de référence de Pêches et Océans Canada et du Plan de protection des océans. Cette initiative vise à acquérir des données environnementales de base qui contribuent à la caractérisation des zones côtières d’importance en soutient aux évaluations fondées sur des preuves et la prise de décisions de gestion afin de préserver les écosystèmes marins. Les données acquises lors des relevés comprennent aussi : 1) les données d’occurrence des taxons d'invertébrés épibenthiques et de végétation aquatique submergée provenant d’un système de caméras photo déposé, 2) les données d’occurrence des poissons et invertébrés observés dans des échantillons vidéo provenant d'un système de caméras vidéo sous-marines appâté, 3) la classification du substrat basée sur les échantillons photos récoltés avec le système de caméras déposé, 4) des mesures océanographiques de la colonne d'eau d’un CTD Seabird 19plus V2 type profilage (conductivité, température, profondeur, rayonnement photosynthétique actif, pH, oxygène dissous), 5) les concentrations de nutriments (NO2, NO3, NH4, PO4, SiO3) et carbone organique dissous (DOC) et 6) la vitesse et la direction du courant mesurées par des inclinomètres. Les deux premiers éléments sont disponibles en tant que jeux de données indépendants sur le portail OBIS. Pour obtenir les données des éléments 3 à 6 et/ou les données biologiques récoltées sur différents taxons de poissons et invertébrés, veuillez contacter David Lévesque ou Marie-Julie Roux.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
