Coastal Biodiversity of the Benthic Epifauna of the St. Lawrence Estuary (2018-2019)
St. Lawrence Global ObservatoryThe North Shore of the Lower Estuary (Upper North Shore, Quebec) is a productive coastal system where many commercial species of benthic invertebrates are fished in the infralittoral (10-20 m) and circalittoral (20-50 m) zone. However, little data exist on the…

Biodiversity of the Planning for Integrated Environmental Response Coastal Survey in the St. Lawrence Estuary and Gulf (2017–2021)
St. Lawrence Global ObservatoryThe Planning for an Environmental Response (PIER) initiative falls under the umbrella of the Government of Canada’s Oceans Protection Plan (OPP), whose goal is preserving marine ecosystems vulnerable to increased transportation and the development of the…

Aquatic invasive species (AIS) program of the eastern Atlantic coast from 2006 to 2019 - Data from Québec's region.
St. Lawrence Global ObservatoryFisheries and Oceans Canada established a program to monitor aquatic invasive species (AIS) on the eastern Atlantic coast from 2006 to 2019 (activities into the five Atlantic provinces). The data in this database are those of the Quebec region, whose territory…

Fish and Invertebrate Assemblages in Coastal Areas of the St. Lawrence Estuary (north shore) Sampled With a Beam Trawl
St. Lawrence Global ObservatoryThis 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…

Hypoxia, Driver of Environmental Change: eDrivers Project for the St.Lawrence System
St. Lawrence Global ObservatoryThe data used to characterize hypoxia come from the Department of Fisheries and Oceans’ (DFO) Atlantic Zone Monitoring Program survey in late spring and fall of 2013 to 2017, as well as from DFO’s annual multispecies surveys for the northern Gulf in August and…

Commercial fisheries intensity, Driver of Environmental Change: eDrivers Project for the St.Lawrence System
St. Lawrence Global ObservatoryThe impacts of fisheries activities in the St. Lawrence are evaluated using DFO fisheries logbooks program. While logbooks are not mandatory for all fisheries in the St. Lawrence, they still provide a very thorough overview of the spatial distribution and…

Sea Surface Temperature Anomalies, Driver of Environmental Change: eDrivers Project for the St.Lawrence System
St. Lawrence Global ObservatoryThe data used to characterize surface-water temperature anomalies come from the Department of Fisheries and Oceans’ (DFO) Atlantic Zone Monitoring Program. The surface-water layer is characterized using sea surface-water temperature (SST) monthly composites…

Toxic algae, Driver of Environmental Change: eDrivers Project for the St. Lawrence System
St. Lawrence Global ObservatoryThe data we use to describe the risk of toxic algae come from an expert based map delineating the areas where coastal areas are at risk from five different toxins. The map presents coastal areas at risk from: 1) paralytic shellfish poisoning (PSP) toxins from…

Acidification, Driver of Environmental Change: eDrivers Project for the St. Lawrence System
St. Lawrence Global ObservatoryOceans are the largest reservoirs and sinks of atmospheric carbon dioxide (CO2). Its uptake increases seawater acidity and lowers the saturation state of waters with respect to calcite (ΩC) and aragonite (ΩA), the two most common CaCO3 polymorphs that…

Sea Bottom Temperature Anomalies, Driver of Environmental Change: eDrivers Project for the St.Lawrence System
St. Lawrence Global ObservatoryThe data used to characterize bottom-water temperature anomalies come from the Department of Fisheries and Oceans’ (DFO) Atlantic Zone Monitoring Program. Bottom-water temperatures are interpolated in the Gulf using conductivity-temperature depth (CTD)…

Characterization of the Batture-aux-Alouettes Kelp Bed, Baie-Sainte-Catherine, Quebec
St. Lawrence Global ObservatoryThis project aims to characterize the kelp bed of the Batture-aux-Alouettes, a preferred food source for the green sea urchin (Strongylocentrotus droebachiensis) which is fished commercially in Quebec. This dataset presents an assessment of the abundance and…

Use of the MiFish Marker (12S) for the Development of an Approach for Characterizing Coastal Species Using Environmental DNA (eDNA)
St. Lawrence Global ObservatorySpecies characterization by environmental DNA (eDNA) is a method that allows the use of DNA released into the environment by organisms from various sources (secretions, faeces, gametes, tissues, etc.). It is a complementary tool to standard sampling methods…
