The study introduces an innovative method for estimating meridional heat transport (MHT) across latitudes. By combining diverse oceanographic approaches, including remote sensing (gravimetry, altimetry), in-situ observations, and advanced statistical modeling, the study bridges several domains of ocean science. It opens the door for things such as an improved estimation of ocean heat content, surface fluxes, sea level variability, currents and enhanced error characterization in satellite observations. The new method could serve as the foundation for alternative estimates of both MHT and the Atlantic Meriodional Circulation (AMOC) that do not depend on costly, geographically limited in-situ observing arrays, which is especially beneficial if it allows the AMOC to be observed across a range of latitudes.
