My Research has followed two main themes; the first is Paleoceanography and the second is investigating Coral reef ecosystems to assess the impact of higher pCO2 on reef sustainability into the future, not just in Australia, but globally. These investigations led my research team to discover that Dolomite is being deposited in crustose Coralline Algae on the margins of reef platforms. Following up on this discovery continues at pace with detailed studies progressing with local collaboration with the Research School of Physics as well as geochemical mass-balance studies under way. We continue to take advantage of the Coral Reef coring that I did in the previous decade to construct detailed climate records that extend back thousands of years with one objective to be able to compare Early and Late Holocene climate records from Northern Australia.
