Fig. 4: Temporal variability of the water properties in the Irminger Sea from Argo data. Variability between 2010 and 2018 of a salinity (psu), b potential temperature θ (C), c oxygen concentration (μmol kg−1), and d Apparent Oxygen Utilization AOU (μmol kg−1) computed from Argo data in the Irminger Sea. The dashed black contours highlight the lower and upper boundaries of the Labrador Sea Water (LSW) layer. Note that the vertical white lines indicate missing data for interpolation.
