Short summary
The instability of the Azores Current often generates large eddies that can transport heat, salt, and biological properties. Using 10 000 Argo profiles and 20 years of satellite data, this study shows that eddy cores deepen and intensify westward. Anticyclones have warm and salty cores, while cyclones are cold and fresh. In general, the vertical movement of the density surfaces shapes their vertical structure, while the interior transport of different water masses dominates near the surface.
