A 2021 study funded by Fisheries and Oceans Canada applied a Nitrogen Loading Model to estimate Total Nitrogen Load from human sources for 109 coastal watersheds bordering the Bay of Fundy and Scotian Shelf. The dataset includes calculated loads from point and non-point sources like wastewater and fertilizer, plus two eutrophication risk indicators for 40 coastal embayments. This research was published in Estuarine, Coastal and Shelf Science (Kelly et al., 2021).
Aerial survey data estimates ringed seal (Pusa hispida) density across a latitudinal gradient in the eastern Canadian Arctic. The dataset captures the species' response to regional variation in sea-ice conditions, showing an order of magnitude lower density at higher latitudes with multiyear ice. Data is provided by Fisheries and Oceans Canada.
Three northern New Brunswick estuaries—Bouctouche, Tabusintac, and Cocagne—were surveyed using a novel towfish package combining underwater video and sidescan sonar. The dataset includes maps of eelgrass cover, health (epiphyte load), and ancillary bottom features like algal growth and bacterial mats. The data was published in November 2017 by the Coastal Ecosystems Science Division of Fisheries and Oceans Canada.
A 2021 survey used a novel towfish integrating sidescan sonar, video, and echosounder to map the nearshore seabed from the shoreline to 10 meters depth across Bedford Basin, Inner Harbour, and Outer Harbour. The resulting geospatial data distinguishes zones by substrate type, benthic invertebrates, and macrophyte canopy. The data is intended to support management questions like habitat compensation project placement.
Fisheries and Oceans Canada conducted a scallop stock assessment and biodiversity survey in the Magdalen Islands (fishing area 20) using a dredge approximately every 1-2 years since 1992. The survey documents occurrences of sea scallops, Icelandic scallops, and associated epibenthic invertebrates and demersal fish by station, with taxonomic validation using the World Register of Marine Species. Sampling occurs at depths of 10 to 38 meters using a fixed random sampling plan.
Fisheries and Oceans Canada provides spatial distribution data on Spotted Wolffish relative occurrence from annual groundfish research surveys. The dataset aggregates catch and effort data into 100 km² cells for the Québec (1978-2008) and Gulf (1971-2008) regions. It maps the probability of catching a Spotted Wolffish per set within each cell.
Fishery-independent catch, effort, location, and biological data from multi-species longline surveys on the northern British Columbia coast. The Outside North Hard Bottom Longline survey series began in 2006 and is conducted biennially, covering the mainland coast north of Milbanke Sound and the Haida Gwaii region. Data is collected by Fisheries and Oceans Canada in collaboration with the Pacific Halibut Management Association using chartered commercial vessels.
Fisheries and Oceans Canada provides spatial data on the relative occurrence of northern wolffish from annual groundfish research surveys. The dataset aggregates catch and effort data by 100 km² cells, covering the Estuary and Gulf of St. Lawrence from 1971 to 2008. It maps the probability of catching the species based on research trawl surveys and Sentinel Fisheries programs.
Ecological and human use data layers used in a 2016-17 Marine Protected Area network analysis for the Scotian Shelf-Bay of Fundy Bioregion. The layers, modified for the analysis, include information on biodiversity and commercial fishing impacts. The dataset is documented in a 2021 technical report.
Canadian Pacific waters contain predicted occurrence layers for 65 groundfish species at a 1 km resolution. The dataset includes species richness and median standard error per grid cell, derived from integrated fisheries-independent survey data. It covers seafloor habitats between 10 and 1400 meters depth with mean summer salinity above 28 PSU.
Kernel density estimation (KDE) was applied to trawl survey data from Eastern Canada, including the Gulf of Saint Lawrence, to model biomass surfaces for sponges, small and large gorgonian corals, and sea pens. The analysis updates previous work with up to 5 additional years of data and identifies significant concentration areas. The dataset is provided by Fisheries and Oceans Canada and includes polygon and point data formats.
Quebec's Department of Fisheries and Oceans provides biological data on commercially caught redfish (Sebastes sp.) in the Estuary and Gulf of St. Lawrence. The dataset includes sample weight, fish length, sex, and specimen counts, covering the periods 1980-1996, 1999-2013, 2015-2016, and 2019. Data was collected by specialized DFO staff at wharves or at sea to support stock assessments.
A coastal surficial substrate layer for the Scotian Shelf and Bay of Fundy, created by Fisheries and Oceans Canada. It integrates geological characterizations from NRCan with digital elevation models and substrate samples to classify grain size and primary habitat type. Each characterization includes a ranking of confidence and original data resolution.
Fisheries and Oceans Canada data describes the likelihood of American Lobster presence in Area Response Planning pilot regions. The analysis is based on a stratified random bottom trawl survey design from the Ecosystem Survey. This dataset was created for consideration in oil spill response planning and published in June 2018.
Approximately 1,000,000 geospatial points at a 250-meter resolution provide relative exposure index, unweighted fetch, and effective fetch data for the coastal zone. The dataset was produced by Fisheries and Oceans Canada using a 5-kilometer coastal buffer and GIS analysis. It supports the study of wave energy and coastal processes.
Spatial distribution data maps the relative occurrence of Atlantic Wolffish from groundfish surveys in the Estuary and Gulf of St. Lawrence. The dataset aggregates catch and effort data into 100 km² cells for the Québec (1978-2008) and Gulf (1971-2008) regions, calculating occurrence probability from set records. It supports analysis of species distribution across multiple time series from research surveys and the Sentinel Fisheries program.
Fisheries and Oceans Canada collected water quality and plankton community observations from multiple georeferenced stations in Toronto Harbor. Data includes physiochemical measurements like temperature and chlorophyll-a, biological metrics for phytoplankton and zooplankton, and microbial community parameters. This dataset supports the evaluation of Beneficial Use Impairments related to plankton degradation and habitat loss.
A geospatial dataset delineating the likelihood of seasonal Snow Crab presence in the Bay of Fundy and Port Hawkesbury areas of Nova Scotia. The data was created by the Coastal Oceanography and Ecosystem Research section of Fisheries and Oceans Canada, based on a review of scientific and local knowledge sources as of March 2017. It was published in June 2018 to support Area Response Planning under the World Class Tanker Safety System initiative.
A study analyzes the biodiversity associated with Vazella pourtalesi glass sponge grounds in Emerald Basin on the Scotian Shelf. The research uses in situ photographs and trawl catch data to examine community composition, species density, and abundance of epibenthos and fish. It provides evidence of the sponge grounds' role in shaping deep-sea community structure.
A habitat suitability model for soft-shelled clams (Mya arenaria) in the Fisheries and Oceans Canada Maritimes region classifies areas as 'Not Suitable', 'Suitable', or 'Suitable and Validated'. The model integrates substrate classification and bathymetric data from 0 to 70 meters depth. It was validated using clam harvesting intensity and infraction location data from DFO and Conservation and Protection programs.
