Which ocean phenomenon spreads invasive species during El Niño?

💡 Explanation

Suppressed equatorial upwelling allows invasive species normally restricted by temperature or nutrient gradients to disperse because it weakens nutrient transport from the deep ocean to the surface. Therefore species spread, rather than being contained by temperature gradients intensified by upwelling.
