"where did this definition of 'acidification' come from? it was beat into my head in junior high that nothing is an acidic until its pH is <7. if an alkaline substance drops in pH it is still a base until it hits 7, at which point it would be 'neutral'. i guess saying that there are areas where sea water is 'less alkaline/less basic' isnt as scary sounding as saying that the ocean is 'acidifying?'" . . . .
