Thermograph Network in the Gulf of St. Lawrence

Le commandant du NGCC Amundsen, Alain Gariépy, le chef officier Jean Gaumond et les scientifiques Guillaume Massé et Louis Fortier prennent grand plaisir à répondre aux questions de l’animatrice.
Oceanographic buoys

The thermograph network program led by a scientific team from the Maurice Lamontagne Institute was started in 1993 with six monitoring stations. The main objective was to measure seawater surface temperatures in the Estuary and Gulf of St. Lawrence, and to maintain a database.

Today, the measurements are no longer limited to the surface temperature of the water: some stations are equipped with multi-instrument platforms that make it possible to measure oceanographic, optical and meteorological parameters. There are now some 25 stations in operation. About half of them are found on Canadian Coast Guard buoys, while the others are mainly on buoys of the Maurice Lamontagne Institute. The buoys are all launched and recovered by Canadian Coast Guard teams.

The water temperatures from the network are used to validate the hydrodynamic models, the satellite surface temperature images or to monitor certain commercial species such as the lobster.

A technical report has just been published. It focuses exclusively on the seawater temperature records with the goal of facilitating their use by identifying available data as well as missing data records during the period from 1993 to 2014. Tables and a figure show the valid data records for each station for every year. Several examples of physical oceanographic phenomena in the program's coastal waters were also presented.

Fin whales

The Atlantic population of fin whales was reduced by whaling during much of the 20th century. Since 1971, however, the species has not been hunted in Canada and sightings remain relatively common off the Atlantic coast and in the Estuary and Gulf of St. Lawrence.

The species was designated “special concern” in May 2005 by the Committee on the Status of Endangered Wildlife in Canada and was officially added to Schedule 1 of the Species at Risk Act in July 2006.

Fisheries and Oceans Canada, in collaboration with its partners, has produced a management plan that describes threats and proposes management measures to maintain the population. This management plan is now on the Species at Risk Public Registry for a public comment period until August 8, 2016.

Conviction for Fisheries Act Violations

Fisheries and Oceans Canada, Quebec Region, has released the names of fishermen who have received fines for violations of the Fisheries Act and continues to strictly enforce its zero tolerance policy for offenders. The Department has a mandate to protect and conserve fishery resources and is ever vigilant in its efforts to prevent poaching of marine resources.

Fisheries and Oceans Canada encourages the public to report poaching incidents by using the online form or calling 1-800-463-9057. All reports are confidential.
