Satellite‐derived time series for the California Current System (CCS) showed marked changes in the surface chlorophyll a concentration (Chl, mg m −3 ) associated with the 1997–98 El Niño. In addition to the previously known decrease in Chl off Southern California (Fiedler, 1984), we also observed a significant increase of Chl off Baja California. Whereas the extent of eutrophic (Chl >1.0) areas decreased throughout the CCS, the extent of mesotrophic areas (0.2
