Photosynthesis and Calcification of the Green Calcareous Algae Halimeda under Ocean Acidification and Climate Change Conditions

Ocean acidification is known as the reduction of pH in the oceans due to the absorption of excess atmospheric CO2 produced by human activities. Additionally, CO2 emissions contribute to the greenhouse effect that is known to be one of the main causes of climate change. Similar to corals and coralline algae, the marine macroalgae in the genus Halimeda are a major carbonate producer. Halimeda are calcareous green algae that live in warm seas near and associated with coral reefs. Therefore it is important to understand what factors affect the capacity of this macroalgae to provide habitat. The objective of my research is to (1) understand how the physiological processes of photosynthesis and calcification in Halimeda will respond to the synergistic effect of CO2, light and temperature, and (2) predict the carbonate production by this calcifying alga under future ocean acidification and climate change conditions throughout a series of mesocosm experiments and field work.
