Thermographs Network of St. Lawrence Estuary and Gulf

Sea Surface Temperature Subsurface Temperature

The thermograph network at the Maurice Lamontagne Institute (IML) of Fisheries and Oceans Canada (DFO) has been measuring temperature almost continuously since 1993 at depths generally ranging from 1 to 30 meters. Thermograph data from 2010 to 2013 are available in the “Data and Resources” section of this dataset. Data prior to 2011 are available on OGSL via the SGDE (MPO). For more information please see [data context] (https://ogsl.ca/fr/conditions-maritimes-thermographes-mpo-contexte/).

**Parameter: ** water temperature.

Access the data in the [MARINE CONDITIONS] application (https://ogsl.ca/conditions/).
