Sea Surface Temperature Anomalies, Driver of Environmental Change: eDrivers Project for the St.Lawrence System

The data used to characterize surface-water temperature anomalies come from the Department of Fisheries and Oceans’ (DFO) Atlantic Zone Monitoring Program.

The surface-water layer is characterized using sea surface-water temperature (SST) monthly composites from Advanced Very High Resolution Radiometer (AVHRR) satellite images obtained from the National Oceanic and Atmospheric Administration (NOAA) and European Organization for the Exploitation of Meteorological Satellites (EUMETSAT). Images used are from DFO’s Maurice Lamontagne Institute at a 1 km resolution from 1985-2013 and from DFO’s Bedford Institute of Oceanography (BIO) Operational Remote Sensing group at a 1.5 km resolution since 2014. Monthly anomalies were constructed as the difference between monthly averages and the 1985-2010 climatological mean for each month.

It is possible to consult the scientific report of the eDrivers project: Characterizing Exposure to and Sharing Knowledge of Drivers of Environmental Change in the St. Lawrence System in Canada and the additional data. It is possible to consult the application eDrivers.
