Which outcome reliably indicates the increased frequency of El Niño events on coastal kelp forest biomes?

💡 Explanation

Decreased kelp biomass results from El Niño disrupting the thermocline's positioning thereby reducing coastal upwelling of nutrient rich waters. This change reduces algal productivity because lower availability of nitrogen & phosphorous limit kelp growth, therefore a signal of deepening thermocline is shown, rather than more nutrients from decreased temperatures strengthening stability.
