Le Saint-Laurent au bord de l’asphyxie | La semaine verte

The St. Lawrence River, like many marine areas around the world, is literally on life support. Oxygen is becoming scarce in certain areas: a phenomenon called hypoxia, which is accelerating with climate change. An underwater odyssey has allowed Quebec researchers to access the hypoxic depths of the Laurentian Channel and better understand the impact of hypoxia on marine species and the fishing industry. To breathe new life into environments affected by hypoxia, researchers are also exploring the idea of ​​artificially reoxygenating them. This concept is not unanimously accepted in the scientific community.
