This transect, which runs off the coast of Brazil since 2004 and has produced more than 40 realizations, supports the MOVAR Project (from Portuguese: Monitoring the upper ocean transport variability in the western South Atlantic). This transect is critical to investigate the fluctuations of the zonally integrated baroclinic transport of the Brazil Current , and to complement other South Atlantic Observations that will provide insights on the link between the variability of the subtropical gyre and the meridional heat transport.
