International audience;  At their generation site, 50% of observed eddies have non-significant isopycnal temperature/salinity (θ/S) anomalies in the TAO.  On density-coordinates, both CEs and AEs can exhibit significant positive, negative or n

We study mesoscale eddy characteristics in the tropical Atlantic Ocean, using 23 years of daily altimetry sea level anomalies. Eddies are mainly generated in the eastern boundary upwelling systems and in the Brazil Current region. Their westward prop
