Fisheries and Oceans Canada (DFO) conducts an annual multidisciplinary scientific survey with a bottom trawl in the Estuary and the northern Gulf of St. Lawrence since 1978. Over the years this survey has been conducted on five vessels: the MV Gadus Atlantica (1978-1994), the MV Lady Hammond...

Witch Flounder otoliths are collected from scientific surveys, fisheries observers on fishing vessels and from scientific sampling of commercial fisheries. The otoliths collected are placed in paper envelopes, recorded and held in a climate-controlled storage facility. Digital images of each pair...

This collection of eelgrass data has been collated to produce a national map of the location and distribution of eelgrass beds across Canada. The data providers collaborating in this initiative include Federal, Provincial and Municipal government departments and agencies, academia,...

Atlantic Cod otoliths are collected from scientific surveys and from scientific sampling of commercial fisheries. The otoliths collected are placed in paper envelopes, recorded and held in a climate-controlled storage facility. Age determination is performed yearly on the available samples....

A rotary screw trap (RST; also known as a smolt wheel) is used to perform a capture-mark-recapture experiment on the main stem of the Margaree River. Smolts are captured at the wheel, a subset are tagged (max 200 individuals daily) and released upriver. Individuals not tagged are enumerated and...

The Ocean Data Inventory database is an inventory of all of the oceanographic time series data held by the Ocean Science Division at the Bedford Institute of Oceanography. The data archive includes about 5800 current meter and acoustic doppler time series, 4500 coastal temperature time series...

In Canada, DFO assessments have reported a high probability of significant climate change impacts in all marine and freshwater basins, with effects increasing over time (DFO 2012a, 2012b), while climate projections indicate that ecosystems and fisheries will be disrupted into the foreseeable...

Records of marine mammal sightings (N = 4,572) collected by ASOs and submitted to Fisheries and Oceans Canada (DFO) regions between 1990-2022, across three DFO regions: the Arctic, Newfoundland and Labrador, and the Maritimes. Methods for compilation and summary statistics are provided in the...

Summary The Quebec region of the Department of Fisheries and Oceans (DFO) is responsible for the assessment of several fish and invertebrate stocks exploited in the Estuary and the northern Gulf of St. Lawrence. The commercial catches sampling program is one of the sources of information used...

This service provides routeing measures. These include established (mandatory) direction of traffic flow, recommended direction of traffic flow, separation lines, separation zones, limits of restricted routeing measure, limits of routeing measures, precautionary areas, archipelagic sea lanes...

As part of the Musquash Marine Protected Area (MPA) Monitoring Plan, this project was implemented to establish a baseline for infaunal biodiversity for this area. Data collection began in 2010 and contributed monitoring information for productivity, biodiversity, and habitat indicators within...

These datasets provide information pertaining to sediment grain size, porosity, organic content, total carbon and nitrogen concentrations, trace element concentrations, chlorophyll and phaeopigment concentrations, and meiofauna and macrofaunal abundance in Simoom Sound between November, 2000, and...

Pacific Herring roe catch data for British Columbia from 1999 to 2023. There are five major stock assessment regions: Haida Gwaii, Prince Rupert District, Central Coast, Strait of Georgia, and West Coast of Vancouver Island; and two minor stock assessment regions: Area 2W and Area 27. Herring roe...

Catch, effort, location (latitude, longitude), relative abundance indices, and associated biological data from groundfish multi-species bottom trawl surveys in Queen Charlotte Sound. Introduction The Queen Charlotte Sound (QCS) synoptic bottom trawl survey was conducted annually from 2003...

The Fisheries and Oceans Canada (DFO) ecosystem surveys consist of research vessel survey data collected to monitor the distribution and abundance of fish and invertebrates throughout the Scotian Shelf, Bay of Fundy and Georges Bank. The surveys follow a stratified random sampling design, and...

"Fall" missions occur primarily in October and November, but sets from September and December are also present in the data. Collected data includes total catch in numbers and weights by species. Length frequency data is available for most species, as are the age, sex, maturity and weight...
