Abstract:
The TRACOS (Tropical Atlantic Circulation and Overturning at 11°S) array at 11°S between Brazil and Angola consists of ship and moored observations as well as pressure inverted echosounders at the western and eastern boundary. 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.
