Combined Effects of Ocean Acidification and Warming on Calcification Rate and Skeletal Morphology of the Caribbean Reef-building Coral Siderastrea siderea ...
Atmospheric pCO2 is predicted to rise from 400 to 900 ppm by year 2100, causing seawater temperatures to increase by 1-4 °C and pH to decrease by 0.1-0.3. Sixty-day experiments were conducted to investigate the independent and combined impacts of acidification (pCO2=425/915 ppm) and warming (T=28/32...
