| Assessing the Risk of Ocean Acidification for the Great Barrier Reef Recent climate change research is focused on the potential consequences of “ocean acidification”, a process that poses a threat to the calcification of scleractinian corals and other marine calcifiers due to the lowered saturation state of aragonite. However, the impacts of ocean acidification on the photo-physiology of coral symbioses are poorly understood. Furthermore, a very recent study (Anthony et al., 2008) has found that CO2 levels representing a year 2100 Intergovernmental Panel on Climate Change (IPCC) scenario lead to loss of productivity and bleaching. During my PhD, we will investigate the physiological and genetic changes that lead to this stress and the effect on coral reef ecosystems by: 1. Investigating the implementation of photoprotective mechanisms under several predicted future scenarios of CO2 and temperature; 2. Determining the changes and variability in gene expression in populations of corals on the Great Barrier Reef.
