TL;DR: The Atlantic Meridional Overturning Circulation (AMOC) is one of the major sources of energy and carbon flux in the North Atlantic Ocean as mentioned in this paper, and it has been extensively studied in the literature.

TL;DR: The Prediction and Research Moored Array in the Tropical Atlantic (PIRATA) as discussed by the authors is a multinational program initiated in 1997 in the tropical Atlantic to improve our understanding and ability to predict ocean-atmosphere variability.

TL;DR: In this article, a multi cruise data set of microstructure observations is used to infer regional and seasonal variability of upper ocean mixing and diapycnal heat flux within the Atlantic cold tongue (ACT) region.

TL;DR: The tropical Atlantic observing system is motivated by goals to understand and better predict phenomena such as tropical Atlantic interannual to decadal variability and climate change; multidecadal variability, its links to the meridional overturning circulation; air-sea fluxes of CO2 and their implications for the fate of anthropogenic CO2; the Amazon River plume and its interactions with biogeochemistry, vertical mixing, and hurricanes; the highly productive eastern boundary and equatorial upwelling systems; and oceanic oxygen minimum zones, their impacts on biogeochemical cycles and marine ecosystems,

TL;DR: In this article, the authors present results from two research cruises and the first 10.5 months of moored observations in comparison to the observations a decade ago, showing that the average transports of the North Brazil Undercurrent and the Deep Western Boundary Current (DWBC) have not changed between the observational periods.
