Packet 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 of a Bjerrum ("B’YAIR-um") plot. A decrease in this quantity drives the CCD upward, damaging the habitat (15[1])of coccolithophores (-5[1])(“kok-oh-LITH-oh-fohrs”). Aragonite-using organisms (-5[1])are the first to be affected by changes in this quantity. (15[1])(*) Coral bleaching (10[1])is exacerbated (-5[3])by a (-5[1])global (-5[1])decrease in (10[1])this quantity. (10[2]-5[2])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 (-5[1])quantity through ocean acidification? (10[1])■END■ (10[9])

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