Have coral calcification rates slowed in the last twenty years?
International audience This paper reports a reanalysis of calcification rates of 328 Porites cores from the Great Barrier Reef from which previous workers have concluded that a 14% reduction in calcification rates has occurred between 1990 and 2005. In this reanalysis it is shown that the apparent r...
