The South Atlantic Ocean is a major component of the climate system, regulating the intensity of the Atlantic Meridional Overturning Circulation (MOC). The circulation at depth controls the efficiency of the AMOC, connecting the North Atlantic Deep Waters with the Antarctic Bottom Waters; furthermore, the circulation patterns at the surface and intermediate layers control de returning limb of the AMOC, linking the very cold subducting regions of the Southern Ocean with the tropical and equatorial upwelling regions. Despite its regional and global relevance, the South Atlantic is a relatively unexplored region.
This effort will analyse existing data, produce valuable new data sets, and will explore some principal physical and biogeochemical processes occurring in the South Atlantic Ocean. The field work will combine traditional and innovative measurements, complementing the ongoing international sampling efforts (through instrumented platforms and remote sensing) and numerical modelling. Field sampling will include two transoceanic cruises and the monitoring of zonal flows in the interior ocean, in a region that has been recently identified as a gateway for both the starting and returning limbs of the AMOC (South Atlantic Gateway, SAGA).
