The accumulation of nutrients, what is called eutrophication, in the marine waters of the St. Lawrence Estuary is raising concerns for aquatic life.

It results in proliferation of harmful algae, but also development of acidified areas poor in dissolved oxygen. Our researchers have been studying various aspects of this phenomenon. Using newly created digital tools, they have managed to assess the contribution of nitrate inputs to oxygen depletion and acidification of the water. These results are explained in two scientific articles.
