Integrated nutrient data for nitrate, phosphate, and silicate from 49 stations in the Estuary and Gulf of St. Lawrence. The dataset includes time series from 2013 to 2022, with separate layers for June and autumn surveys. It is produced by Fisheries and Oceans Canada's Atlantic Zone Monitoring Program.
December 2024 data from four regional annual multispecies trawl surveys in the Northwest Atlantic, used to characterize mesoscale biological assemblages. The analysis identified 3 to 6 predominant assemblage types per region, with indicator analyses selecting 3–34 emblematic taxa for each type. Random forest models predicted assemblage distributions from environmental covariates with high accuracy (AUC > 0.95).
Fisheries and Oceans Canada provides mean pelagic fish total biomass data from 2014 to 2023 for the Estuary and Gulf of St. Lawrence. The data aggregates fish biomass from annual multidisciplinary surveys, averaged within 10 km x 10 km grid cells. Separate survey layers are presented due to non-comparable fishing gear between northern and southern surveys.
Nova Scotia's Atlantic coast provides monthly field data on seagrass productivity and resilience from May 2018 to July 2019. The dataset includes vegetative and reproductive shoot density, above and belowground biomass, and plant morphology measurements from 10 sampling stations per site. It also contains high-frequency bottom temperature records logged at 15-minute intervals.
Fisheries and Oceans Canada provides cumulative commercial fishing effort data for Canada's Atlantic and Eastern Arctic waters from 2005 to 2023. The data, derived from logbook and vessel monitoring system records, is standardized into percentiles where the top 20th percentile indicates cells of most intense fishing activity.
2014-2023 bottom salinity data from 49 stations in the Estuary and Gulf of St. Lawrence, with time series for June and autumn surveys. The dataset includes CSV files with columns for Station, Latitude, Longitude, Date(UTC), Sounding(m), Depth/Profondeur(m), and Salinity/Salinité. Data was collected by Fisheries and Oceans Canada's Atlantic Zone Monitoring Program to track marine environmental changes.
Fisheries and Oceans Canada's dataset contains 403 survey stations from 1997 and 2007-08 on three scallop fishing grounds. It records presence/absence for 68 benthic invertebrate taxa and includes 14 environmental variables like seabed depth and temperature. The data also features a 68x27 taxa-by-traits matrix using fuzzy coding for seven biological traits.
Spatial distribution of Thorny Skate presence in the Estuary and Gulf of St. Lawrence, expressed by catch weight aggregated into 100 km² cells. The data originates from annual Department of Fisheries and Oceans groundfish research surveys conducted between 2004 and 2010, following standardized trawling protocols.
Fisheries and Oceans Canada provides mean total biomass estimates for demersal fish from 2014 to 2023 in the Estuary and Gulf of St. Lawrence. Data is aggregated from annual August and September multidisciplinary surveys, averaged within 10 km x 10 km grid cells. The dataset is presented as distinct layers for the northern and southern surveys due to differing fishing gear protocols.
13 years of commercial-size sea scallop abundance data from the Bay of Fundy, collected via unlined dredge surveys. Each row represents a standardized tow, with scallop counts binned into 5-mm shell height increments and prorated to a swept area of 4267 m². The dataset includes a comparative gear survey from 2012 and supports the findings of Hebert et al. (2025).
Fisheries and Oceans Canada provides field measurements of eelgrass (Zostera marina) from sites along the Atlantic coast of Nova Scotia. Data includes percent cover, shoot density, and plant metrics like leaf length, width, and weight collected in July-August 2022. These measurements support allometric and cover-biomass relationship modeling for non-destructive biomass estimation.
2014-2023 time series of bottom dissolved oxygen measurements from 49 stations in the Estuary and Gulf of St. Lawrence. The dataset includes data from 3 fixed stations and 46 stations grouped into transects, sampled during June and autumn surveys. It is managed by Fisheries and Oceans Canada's Atlantic Zone Monitoring Program (AZMP).
2013-2022 time series of integrated chlorophyll-a concentration (mg/m²) from 49 stations in the Estuary and Gulf of St. Lawrence, managed by Fisheries and Oceans Canada. The dataset includes data from June and autumn surveys, with weekly sampling at the Rimouski fixed station. It provides chlorophyll-a measurements linked to station coordinates, depth ranges, and sampling dates.
Pelagic fish group richness data from 2014 to 2023, estimated by species count per 10 km x 10 km grid cell. Data originates from annual August and September multidisciplinary surveys conducted by Fisheries and Oceans Canada. The surveys aim to monitor biodiversity and the status of marine resources in the region.
Spatial distribution of Winter Skate relative occurrence is based on annual DFO groundfish research surveys from 2004 to 2010. Data are aggregated into a grid of 100 km² cells, calculating the probability of catching the species per set. The dataset supports monitoring of marine resource status and biodiversity in the Estuary and Gulf of St. Lawrence.
More than 120 commercial fishers along the Atlantic coast of Nova Scotia collected juvenile lobster data using scientific project traps. The project records lobster count, sex, length, egg presence, tags, v-notch status, and bottom temperature. Data is managed by the Fishermen and Scientist Research Society with funding from Fisheries and Oceans Canada.
Macrofauna abundance and biomass data from eelgrass and bare soft sediment sites in Atlantic Nova Scotia. The dataset covers collections from 2009 to 2013. It was published by Fisheries and Oceans Canada in 2020 and is associated with peer-reviewed ecological studies.
UNEP-WCMC provides this geospatial dataset of marine and terrestrial protected areas and other effective area-based conservation measures (OECMs) for China. Updated monthly as part of the Protected Planet Initiative, it serves as the primary source for tracking progress toward the Kunming-Montreal Global Biodiversity Framework.
This geospatial dataset tracks marine and terrestrial protected areas and other effective area-based conservation measures (OECMs) within Singapore. Managed by the UNEP-WCMC in collaboration with the IUCN, the records are updated on a monthly basis to support international biodiversity reporting. The data serves as the official record for tracking progress toward the Kunming-Montreal Global Biodiversity Framework's 30x30 target.
4200 kilometers of Quebec's estuarine and maritime coastline were mapped for eelgrass distribution using polygons from the 2022 Coastal Ecosystems Cartography geodatabase. The dataset, created by Fisheries and Oceans Canada and the University of Quebec at Rimouski, includes attributes on vegetation cover, seagrass bed composition, and associated ecosystem names. It integrates field data from over 7300 sampling stations to validate photo-interpretation results.
