PURPOSE: This data relates to the Canadian Science Advice Secretariat (CSAS) Regional Science Advisory Process from the Limit Reference Point and Population Model Review of the Southern Gulf of Saint Lawrence Sea Scallop peer review meeting held on November 1-2, 2023. The SFAs 22 and 24 have...

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...

Fisheries and Oceans Canada (DFO) Maritime Science Branch has collected grain size data from sediment and water column samples using bottle samples, sediment cores, and sediment grabs as part of numerous research projects not only in the Atlantic provinces, but also worldwide. The data collected...

Description: Data on recreational boating are needed for marine spatial planning initiatives in British Columbia (BC). Vessel traffic data are typically obtained by analyzing automatic identification system (AIS) vessel tracking data, but recreational vessels are often omitted or...

Monitoring programs are an important component of Marine Protected Area (MPA) management, providing requisite information on the state of, and changes in, protected ecosystems. Monitoring is required to gauge the efficacy of MPAs towards their conservation objectives and provides information...

The shallow, coastal regions of the world’s oceans are highly productive ecosystems providing important habitat for commercial, forage, endangered, and iconic species. Given the diversity of ecosystem services produced or supported by this ecosystem, a better understanding of its structure and...

Description: Seasonal climatologies for salinity of the Northeast Pacific Ocean were computed to cover the period 2001 to 2020. Historibal observations included all available conductivity-temperature_depth (CTD), bottle and profiling floats in the NODC World Ocean Database, Marine Environmental...

Salmon have a complex hierarchical population structure extending from groups of salmon at individual spawning sites all the way up to taxonomic species. These independently functioning aggregates are defined as Conservation Units (CUs) in the Wild Salmon Policy. A stock management unit (SMU) is...

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...

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...

Map of Canada showing locations of facilities selling nautical charts in both paper and digital formats.

Canadian Hydrographic Service (CHS) has made available all the publishable limits of modern day surveys whose data has been collected since 1989.

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...

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...

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...
