Over the past decades, international efforts to observe and predict the Atlantic Meridional Overturning Circulation (AMOC) have been undertaken by ocean and climate science communities, such as OSNAP. Below is a non-exhaustive list of these organizations.
Collection of Transport Mooring Arrays (Fram Strait, GSR, OSNAP, NOAC, RAPID Array, MOVE, 11°S, SAMBA-SAMOC) can be found here.
Measure the strength and variability of the MOC and the meridional heat and freshwater transport in the South Atlantic.
Aims to better constrain the uncertainties on ocean circulation and provide new information on chemical element fluxes along the OVIDE section.
OVIDE and RREX data can be found on their website.
Since 2002, the Ovide project contributes to the observation of both the circulation and the water mass properties along a section from Greenland to Portugal.
The Reykjanes Ridge Experiment (RREX) aims to investigate the interactions of the ocean currents with the Reykjanes Ridge, a major topographic feature of the North-Atlantic Ocean lying south of Iceland.
Meridional Overturning Variability Experiment
Aims to determine the transport fluctuations across the section between the Lesser Antilles (Guadeloupe) and the Mid-Atlantic Ridge. More info can be found here.
Prediction and Research Moored Array in the Tropical Atlantic
Designed to study ocean-atmosphere interactions in the tropical Atlantic that affect regional weather and climate variability on seasonal, interannual and longer time scales. More info can be found here.
Monitoring the Atlantic Meridional Overturning Circulation
Measure the strength and variability of the MOC in the North Atlantic at 26°N. More info can be found here.
Overturning in the Subpolar North Atlantic Program
Part of the international OSNAP, UK-OSNAP is a partnership between NOC, SAMS, the University of Oxford and the University of Liverpool. More info can be found here.

The METRIC python module enables consistent calculations of Atlantic meridional overturning circulation (AMOC) estimates at various observational arrays from ocean general circulation models. The current version allows AMOC estimates at the RAPID (26.5°N) site, the MOVE (16°N) site, and the SAMBA (34.5°S) site.
