Current research and/or projects
Through environmental monitoring activities, helps to ensure the conservation and protection of aquatic ecosystems.
- Monitoring of wetland vegetation along the St. Lawrence using remote sensing to provide a current portrait of the distribution of major classes of plants.
- Monitors land use in the Great Lakes – St. Lawrence basin in order to determine the relationship between changes in shoreline land use and water quality (development of new indicators).
- Participates in activities aimed at developing water quality monitoring using remote sensing.
- Participates in a project aimed at integrating the various environmental indicators monitored along the St. Lawrence.
- Seeks partnerships to extend current activities over a larger geographic area.
