Noaa S Coral Reef Conservation Program Crcp Ocean Acidification The first station, gbrwis 36,37 (− 23.459° s, 151.927° e), is located in the subtropical southern mid shelf gbr, at ~ 16 m depth in a channel separating the coral reefs of wistari reef from. The phenomenon known as ‘ocean acidification’ results from the dissolution of carbon dioxide in oceanic waters causing a decrease in the ph of the seawater according to the reaction: co 2 h 2 o → hco 3 − h (reaction 1) (where hco 3 − is bicarbonate and h is the acidic hydrogen ion).
Coral Reef Introduction Earth 103 Earth In The Future Ocean acidification (oa) is a process through which dissolution of co 2 into seawater lowers the calcium carbonate saturation state of seawater (Ω) 5. in the marine environment, oa is expected to. In the case of ocean acidification, observations at naturally acidified coral reefs at co 2 volcanic seeps indicate that differential susceptibility to elevated ph among coral taxa may drive a shift towards species with stress tolerant life histories (darling et al., 2012; fabricius et al., 2011), resulting in a change in coral assemblage. Yet in the decade since the in augural international year of the reef in 1997 (2), which called the world to action, coral reefs have continued to deteriorate as a result of human in fluences (3, 4). rapid increases in the atmospheric carbon dioxide concentration ([co2]atm), by driv . ing global warming and ocean acidification, may be the final. Coral reefs are thought to be particularly vulnerable to ocean acidification, because the entire structure of the ecosystem is supported by biogenically precipitated calcium carbonate. as co 2 increases and the saturation state of aragonite (Ω) continues to decline, ocean acidification threatens the very foundation of these valuable ecosystems.
