Sea Surface Temperatures Map

This map shows charts of sea surface temperatures for the previous two weeks at shellfish harvesting locations in BC.

The temperature estimates in the charts are composite values calculated based on night-time observations from several satellite instruments. The temperature estimates are from a one-kilometer square at the location marked on the chart. These estimates represent the foundation sea surface temperature, which is the sea surface temperature that is free of diurnal temperature variability, usually occurring at a depth of about 10 metres below the surface. Data is downloaded daily.

  • These charts are useful to assess temperature trends over time to show warming patterns in the ocean that would affect shellfish harvesting. They do not provide maximum daytime temperatures, temperatures that would be at the surface of the ocean or air temperatures, all of which would normally be higher than the values shown in the graphs. For more resources, see Shellfish Harvesting & Control.

  • The SST product being used in these maps is the “SSTfnd” product”, which is the sea surface foundation temperature. This is the temperature at the first time of the day when the heat gain from the solar radiation absorption exceeds the heat loss at the sea surface, and it is free of diurnal temperature variability.  The sea surface foundation temperature usually occurs at a depth of about 10 metres below the surface.
