Figure 7

Temperature and salinity in the upper 150 m of the water column averaged over the entire shelf and in 5-year intervals from EcoMon data. The open circles demarcate the surface and the triangles mark the 50 m depth. The red dotted line is the average ring signature up to 150 m taken from Argo float data over the period 2011–2020 taken from Silver et al.13. The red triangle marks 50 m within the ring water. Contours of density are also shown at an interval of 1 kg/m3.
