Progressive seawater acidification on the Great Barrier Reef continental shelf
Coral reefs are highly sensitive to ocean acidification due to rising atmospheric CO 2 concentrations. We present 10years of data (20092019) on the long-term trends and sources of variation in the carbon chemistry from two fixed stations in the Australian Great Barrier Reef. Data from the subtropica...

Coral reefs are highly sensitive to ocean acidification due to rising atmospheric CO 2 concentrations. We present 10years of data (20092019) on the long-term trends and sources of variation in the carbon chemistry from two fixed stations in the Australian Great Barrier Reef. Data from the subtropical mid-shelf GBRWIS comprised 3-h instrument records, and those from the tropical coastal NRSYON were monthly seawater samples. Both stations recorded significant variation in seawater CO 2 fugacity ( f CO 2 ), attributable to seasonal, daytime, temperature and salinity fluctuations. Superimposed over this variation, f CO 2 progressively increased by > 2.0 0.3 atm year −1 at both stations. Seawater temperature and salinity also increased throughout the decade, whereas seawater pH and the saturation state of aragonite declined. The decadal upward f CO 2 trend remained significant in temperature- and salinity-normalised data. Indeed, annual f CO 2 minima are now higher than estimated f CO 2 maxima in the early 1960s, with mean f CO 2 now ~ 28% higher than 60years ago. Our data indicate that carbonate dissolution from the seafloor is currently unable to buffer the Great Barrier Reef against ocean acidification. This is of great concern for the thousands of coral reefs and other diverse marine ecosystems located in this vast continental shelf system. |
