St. Lawrence Observation NetworkThe St. Lawrence Observation Network presents real-time water temperatures as well as an access to archives from two data collection networks.
The SINECO network is an operational system for the observation and forecast of water levels operated by the Canadian Hydrographic Service (CHS), Québec Region, and is made up of 23 recording stations. The on-line scientific buoy network includes 5 stations jointly exploited by DFO and the Institut des sciences de la mer de Rimouski (ISMER).
Further developments of this site include adding more data sources and featuring various parameters such as salinity, atmospheric pressure, etc.
