Mass, Heat, and Freshwater Transport From Transoceanic Sections in the Atlantic Ocean at 30°S and 24.5°N: Single Sections Versus Box Models?

The Atlantic meridional overturning circulation (AMOC) is central to the climate of by redistributing mass, heat, and freshwater. Hydrographic sections help monitor its strength at different latitudes, inverse box models provide estimates AMOC, freshwater transports. We have used all available hydrographic zonal 24.5°N 30°S over last 30 years conclude that single section agree with monthly outputs from an ocean general model time cruise. In contrast, using multiple latitudes times year for each three decades are more consistent decadal averages same model. Therefore, solutions affected aliasing represent state However, greatly reduced when assess low-frequency variability.
