Dimethylsulfide (DMS), marine biogenic aerosols and the ecophysiology of coral reefs
Global climate change and the impacts of ocean warming, ocean acidification and declining water quality are adversely affecting coral-reef ecosystems. This is of great concern, as coral reefs provide numerous ecosystem, economic and social services. Corals are also recognised as being amongst the st...
