It is located in the tropical Atlantic where the upper-ocean circulation is a complex superposition of thermohaline and wind-driven flows. The zonally and vertically integrated upper-ocean meridional flow is associated with the upper branch of the Atlantic Meridional Overturning Circulation (AMOC) — a major component of the global climate system. In the tropics, the northward AMOC flow is superimposed by the shallower overturning associated with the wind-driven Subtropical cells (STCs). One of the key regions in the tropical Atlantic is the western boundary current system off Brazil. This region serves as a crossroads for the meridional transfer of mass, heat, and salt between the Northern and Southern hemisphere. The eastern boundary serves as a gateway for equatorial variability in the Benguela upwelling system: The TRACOS array consists of moorings at the western and eastern boundary and bottom pressure measurements on both sides of the basin in 300m and 500m depth.12.9882813.71885-10.83972-10.6685
