Concentrations of dissolved oxygen in the deep waters of the Lower St. Lawrence Estuary (LSLE) have dropped by over 50% over the past two years. The consequences for many marine species, who depend on oxygen to survive, are potentially very serious. A compilation of historical data reveals that dissolved oxygen concentrations in the deep waters of the Lower St. Lawrence Estuary decreased by about 50% during the fifty years between 1934 and 1985. And then remained fairly constant until 2019, when the situation changed dramatically.
