Dissolved oxygen concentration at 300 m depth in the Lower St. Lawrence Estuary (1932–2016, declining trend of 0.89 µmol/kg per decade, significant at 1% level [there is only a 1% possibility that such changes are due to chance]); depth-averaged dissolved oxygen concentration in the Labrador Sea (150–400 m, 1990–2011, declining trend of 0.75 µmol/kg per decade, significant at 1% level); Station P dissolved oxygen concentration at 150 m depth (1956–2017, declining trend 0.61 µmol/kg per decade, significant at 1% level) and at 400 m depth (1957–2017, declining trend 0.19 µmol/kg per decade, significant at 1% level).
