Freshwater: An Observation-Based Estimate of Atlantic Meridional Freshwater Transport. AMFT given by RAPID array at 26.5°N was integrated southward and northward in combination with ocean freshwater content (calculated by salinity) and surface freshwater flux, with the residual of the freshwater budget equation being the AMFT.
