Weak upwelling offshore (yellow arrows) favors production of smaller plankton and spawning of the Pacific sardine, while stronger upwelling near the coast (red arrows) favors production of larger plankton and spawning of the northern anchovy. CCE-LTER region.

Long-term variation in summertime upwelling, seawater density (red line), nutricline depth (blue line), and chlorophyll-a concentration (green line). These properties of the ocean water column are more highly correlated with curl-driven upwelling (gray line) than with coastal upwelling (black line) after 1970. CCE-LTER site.
