Which outcome increases when coastal algal blooms deplete oxygen?

💡 Explanation

Harmful algal blooms consuming ample oxygen promote bottom water hypoxia, because decreased oxygen forces marine life upwards towards the surface; therefore upwelling is increased rather than creating stratification, as deoxygenation exacerbates mortality.
