Observing and Modelling the Meridional Overturning Circulation in the South Atlantic (SAMOC)


The meridional overturning circulation (MOC) in the Atlantic is a key element of the time-variable coupled climate system and may have played a significant role in the subsurface sequestration of heat during the recent global warming hiatus. New in the observing systems monitoring this event is the SAMOC (South Atlantic MOC) Basin Wide Array (SAMBA). 

Extending from South America to Africa, this system includes efforts to monitor zonal fluxes across the Drake Passage and the gap between Africa and Antarctica, which is very poorly sampled to the current date. The SAMOC Working Group seeks to enhance SAMOC by strengthening  the existing international partnership and attracting more participants. 

How SAMOC contributes to POGO priority areas

POGO advocates for a global coverage in the ocean observing system, which is why addressing the imbalance of available observation systems between the northern and southern hemisphere is at the heart of the POGOs Strategy. Coordinating the ongoing and near future actions related to SAMOC contributes to this aim. Working Group participants will attend scientific reunions concerning SAMOC and will hold frequent online discussions in order to design an action plan aimed at the ultimate goal of enhancing the MOC observing system in the South Atlantic.​
