Color-shading: Aviso Duacs2014 sea level anomaly. Daily, 1/4° x 1/4° merged product.
Eddy detection and tracking algorithm: Pegiasco et al., 2015;
Eddy edges correspond to closed sea level anomaly contours and centers are indicated by * for anticyclonic and o for cyclonic eddies. Filters: We only retain eddy trajectories having lifetimes longer than 14 days, mean radii larger than 50 km, and mean amplitudes greater than 2 cm.
