Which mechanism causes localized ocean acidification within a subtropical gyre's convergence zone?

💡 Explanation

When surface water converges in a gyre, downwelling occurs transporting carbon dioxide-rich surface waters to lower depths because surface waters absorb atmospheric CO2. Therefore increased acidity results, rather than bicarbonate upwelling or pollution, which would decrease surface acidity, and photosynthesis, which always lowers surface CO2.
