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
