The last couple of decades have seen a sea change in understanding deep currents in the North Atlantic Ocean. And this change has fundamental importance for explaining the ocean's role related to climate change.
The deep circulation provides a buffer for increased heat and carbon dioxide that would otherwise reside in the atmosphere. For climate studies, understanding the mechanisms driving changes in the meridional overturning circulation (MOC) is essential.
Various basin-scale observational programmes have toppled the traditional view of the deep circulation. Read how our Peter Spain looks at examples of Teledyne RDI's ADCPs in programmes observing the MOC in the subpolar North Atlantic.
