The North Brazil Current (NBC) is a western boundary current that flows off the coast of northeast Brazil and retroflects between 4°N and 10°N.
The NBC sheds large anticyclonic rings that move northwestward along the continental break. (Didden and Schott, 1993). These warm rings could play an important role in the net meridional transport of warm water in the upper layers of the Atlantic Ocean as part of the meridional overturning circulation (MOC).

Time series of geostrophic transport
Geostrophic transport time-series of the NBC Current and its retroflected flow both estimated using a combination of satellite altimetry fields and climatological data. Comparison between results obtained from alimetry and inverted echo sounders (IES). These time-series is updated on a monthly basis. Go
