Fig. 1: Ocean temperature, salinity and age anomalies.

a Ocean temperature, (b) salinity and (c) age anomalies at the LIG compared to PI averaged across 385–601 m depth. Zonally-averaged (d) ocean temperature, (e) salinity, and (f) age anomalies (shading) with density anomalies in kg m⁻³ overlaid (contours).
