Observational records in the oceans are commonly too short to identify significant trends and variability.

Our research into the palaeoceanography and palaeoclimate of the oceans around Australia and Antarctica provides information about the natural background state and variability in the Earth system prior to human influence.

This data gives us context for the changes we see in the modern ocean (for example, increasing temperatures and ocean acidity).

Using different archives and techniques, we aim to understand past changes in ocean composition, temperature, productivity and circulation.
