Round 1: Tossup 2

The capacity to maintain this quantity is considered low for systems with a high Revelle factor. This quantity is plotted on the x-axis (15[2])of a Bjerrum ("B’YAIR-um") plot. A decrease in this quantity drives the CCD upward, damaging (-5[1])the habitat of coccolithophores (-5[1])(“kok-oh-LITH-oh-fohrs”). Aragonite-using organisms are the first to be affected by changes in this quantity. (15[1])(*) Coral bleaching is exacerbated (10[1])by a global decrease in this quantity. This quantity drops when the equilibrium of a bicarbonate-carbonate buffer is altered. For 10 points, increased carbon dioxide uptake causes a decrease in what quantity through ocean (10[1])acidification? (10[1])■END■

ANSWER: oceanic pH [prompt on ocean acidification or acidity or alkalinity before "acidification"; prompt on concentration of carbon dioxide or concentration of CO2 or dissolved inorganic carbon or total inorganic carbon before "carbon dioxide"]
