Wind-driven circulation for the eastern North Atlantic Subtropical Gyre from Argo data
A trans-oceanic section at 24.5°N in the North Atlantic has been sampled at a decadal frequency. This work demonstrates that the wind-driven component of the Meridional Overturning Circulation (MOC) may be monitored using autonomous profiling floats deployed in the eastern North Atlantic Subtropical...

A trans-oceanic section at 24.5°N in the North Atlantic has been sampled at a decadal frequency.
