Clusters of Excellence 80 (EXC): The Future Ocean, Ocean Acidification - Biogeochemical Studies on the effects of ocean accidification

Description: Although ocean acidification due to anthropogenic CO2 emission is inevitable and will extend as long as fossil fuel CO2 continues to enter the atmosphere, our understanding of its biological consequences is in it s infancy. Experiments with tropical reef building corals demonstrated that a lowering of the carbonate ion concentration significantly reduces coral calcification growth. In the middle of this century, many tropical coral reefs may well erode faster than they can rebuild. At present, virtually nothing is known about the effects of seawater acidification on coldwater corals. This gap of information has to be closed urgently, because cold-water corals are living in an environment (high latitude, cold and deep waters) with carbonate saturation already close to unity. Using high-resolution archives like living and fossil coral fragments, we aim to reconstruct past variabilities of ocean acidification (pH) from the initiation of the reefs 8,000 to 9,000 years ago, as well as during their further development in the Holocene.
