Since the inception of the international South Atlantic Meridional Overturning Circulation (SAMOC) initiative in 2007, substantial advances have been made in observing and understanding the South Atlantic component of the Atlantic Meridional Overturning Circulation (AMOC). The goals of the SAMOC initiative are to monitor climatically relevant oceanic fluxes of mass, heat, and freshwater, provide observations to validate and improve numerical models and climate predictions, and understand the impacts of the SAMOC on climate and weather.

In a recent article published in the Journal of Geophysical Research - Oceans, scientists at AOML evaluate the variability of the heat transport in the South Atlantic by developing a new method to measure its changes on a daily basis. This study presents, for the first time, full‐depth, daily measurements of the volume and heat transported by the Meridional Overturning Circulation (MOC) in the South Atlantic at 34.5°S based on direct observations.

First-ever Daily Time Series Reveals the Strength of the Deep Ocean Circulation in the South Atlantic

In a recent study published in the journal Science Advances, oceanographers at AOML and the Cooperative Institute for Marine and Atmospheric Studies for the first time describe the daily variability of the circulation of key deep currents in the South Atlantic Ocean that are linked to climate and weather. The study found that the circulation patterns in the upper and deeper layers of the South Atlantic often vary independently of each other, an important new result about the broader Meridional Overturning Circulation (MOC) in the Atlantic.
