Which risk increases when coastal hydro-engineering prevents upwelling?

💡 Explanation

Increased harmful algal bloom frequency occurs because nutrient replenishment from upwelling ceases and stratification increases, strengthening surface blooms; therefore algal blooms occur rather than pH reduction driven by carbon fluxes.
