This dataset is a compilation of numerous data files recovered as part of a data request in 2024 from a historical archive of DFO research data. Sediment and Suspended Particulate Matter (SPM) samples were collected over more than a decade as part of Dr. Douglas Loring’s research program while...

Description: Chlorophyll-a concentration (a proxy for phytoplankton biomass) was retrieved from the MODIS instrument on the Aqua satellite, with data distributed by the NASA Ocean Biology Processing Group, and averaged into monthly climatological composites. The data span the years 2003-2020...

The Species at Risk (SAR) Program is responsible for carrying out DFO’s mandate under the Species at Risk Act (SARA) to protect, recover and conserve all listed aquatic SAR in Canada. Critical habitat is identified for species listed as Endangered or Threatened under the Species at Risk Act...

Canadian tides and water level station information, benchmarks, observed water level data, and tidal predictions. The Canadian tide and water level data archive presently holds water level observations reported from over a thousand stations, with the earliest dating back to 1848. The number of...

Argo is a global in situ ocean climate monitoring system consisting in an array of over 4,000 free-drifting floats that collect data on ocean temperature and salinity, and sometimes oxygen, in the upper 2000 m of the ocean. It is an international effort, with more than 30 nations contributing...

Description: Night-time sea surface temperature (SST) was retrieved from the MODIS instrument on the Aqua satellite, with data distributed by the NASA Ocean Biology Processing Group, and averaged into monthly climatological composites. The data span the years 2003-2020; records were created at...

Ecologically and Biologically Significant Areas (EBSAs) are areas within Canada's oceans that have been identified through formal scientific assessments as having special biological or ecological significance when compared with the surrounding marine ecosystem. Failure to define an area as an...

Funded under DFO's Marine Conservation Targets Program, this optical imagery benthic survey documents the occurrence and estimated percent cover of the invasive colonial tunicate, Didemnum vexillum in seven drift-camera transects in the 'Head Harbour/West Isles Archipelago/The Passages'...

Description: Night-time sea surface temperature (SST) was acquired from the AVHRR Pathfinder project, with data distributed by NOAA, and averaged into monthly climatological composites. The data span late 1981 through 2010 at 4 km pixel resolution. Methods: AVHRR Pathfinder version 5.3...

Description: Night-time sea surface temperature (SST) was acquired from the AVHRR Pathfinder project, with data distributed by NOAA, and averaged into monthly climatological composites. The data span 1990 through 2020 at 4 km pixel resolution. Methods: AVHRR Pathfinder version 5.3 Level 3C...

The endangered St. Lawrence Estuary (SLE) beluga population is in decline and has shown no signs of recovery despite multiple protection measures. Changes in prey availability and exposure to organohalogen contaminants have been proposed as potential factors limiting the its recovery. Studies on...

These data sets provide information pertaining to shrimp and bycatch estimates associated with beam-trawling and trapping (2001-2002) in Clio Channel. Data sets were compiled and formatted by Meagan Mak. Abstract from report: As part of a project investigating possible modification of marine...

Funded under DFO's Marine Conservation Targets Program, this optical imagery benthic survey captured 16 drift-camera transects in the St. Anns Bank Marine Protected Area (MPA - 4364 km2) and 2 coastal transects west of the MPA, Atlantic Canada from August 15-23, 2023. High-resolution still images...

Description: Seasonal climatologies for Zooplankton biomass in seven size categories were calculated for the period 1990-2019. The data used were a subset of the Fisheries and Oceans Canada, Institute of Ocean Sciences Zooplankton Database. This dataset is incomplete and is regularly updated...

Funded under DFO's Marine Conservation Targets Program, this optical imagery benthic survey captured 24 drift-camera transects from September 22-26, 2023 in the Quoddy Region of the lower, western Bay of Fundy, New Brunswick, Canada. The survey area includes Passamaquoddy Bay, the 'Head...

The Species at Risk (SAR) Program is responsible for carrying out DFO’s mandate under the Species at Risk Act (SARA) to protect, recover and conserve all listed aquatic SAR in Canada. As part of this mandate, this spatial database has been developed to identify areas in which aquatic species...

The Science Branch of Fisheries and Oceans Canada (DFO) in the Newfoundland and Labrador (NL) region has been conducting multispecies research vessel (RV) surveys using a stratified random survey design since the early 1970s. The DFO RV survey dataset represents the longest time series of species...

Description: Seasonal sigma-t climatology of the Northeast Pacific Ocean was computed from historical observations including all available conductivity-temperature-depth (CTD), bottle, expendable bathy-thermograph (XBT), and Argo data in NOAA (http://www.argo.ucsd.edu/), Marine Environmental...
