Researchers from the Australian Institute of Marine Science (AIMS) are currently studying the shallow volcanic CO2 seeps in eastern Papua New Guinea (PNG) in Milne Bay Province to observe how ocean acidification (OA) is affecting the oceans.
"These experiments and field trips are essential to study at first-hand what is occurring in nature when more and more CO2 from the atmosphere mixes with water," said AIMS research scientist, Dr Katharina Fabricius.
When CO2 from the atmosphere dissolves in water, it causes OA, slightly lowering the pH of the water and changing its carbonate chemistry. This in turn makes it harder for a range of marine animals to form their shells and skeletons.
Over the past five years AIMS researche...
