Mean El Niño (EN; a,c) and La Niña (LN; b,d) composites for the surface salinity anomaly (SSA, color) and surface shelf current anomaly (red arrows; significant values only) during winter (December–February; a,b) and spring (March–May; c,d). Gray dots indicate significant salinity anomalies at the 90% confidence level. Black contours depict the 25- and 200-m isobaths.
