Australian membership of the International Ocean Discovery Program:
This project is for a 5-year membership of the International Ocean Discovery Program, the world’s largest collaborative research program in earth and ocean sciences addressing international priorities. The program conducts seagoing coring expeditions and monitoring of instrumented boreholes to study the history and current activity of the Earth, recorded in sediments and rocks below the seafloor. The program’s aims include understanding past global environments on multiple time scales, the deep biosphere, plate tectonics, occurrence and distribution of resources, and generation of hazards. Several multinational expeditions are scheduled and planned in our marine jurisdiction and within the Australasian region. Read moreRead less
High resolution warm ocean records from laminated sediment. This project will produce environmental records during ocean warming events in the geologic past to reveal processes associated with warm oceans similar to those anticipated in the coming century. New Australian technology allows investigation of sediment records at unprecedented time resolution providing insight into processes operating on societally relevant time scales of decades to centuries. This work will open an archive of climat ....High resolution warm ocean records from laminated sediment. This project will produce environmental records during ocean warming events in the geologic past to reveal processes associated with warm oceans similar to those anticipated in the coming century. New Australian technology allows investigation of sediment records at unprecedented time resolution providing insight into processes operating on societally relevant time scales of decades to centuries. This work will open an archive of climate information revealing feedback, thresholds and tipping points from past events previously inaccessible because of technical and conceptual limitations. It will provide critical inputs into models predicting future climate and to illuminate the risks and compensating feedbacks occurring with warming.

Carbon sequestration by mineral surface area as a feedback to climate warming in a greenhouse ocean. The project will investigate a previously unrecognised negative feedback to global warming resulting from sequestration of carbon to marine sediments by soil-formed clay minerals. By studying the past transitions to greenhouse periods, this project will assess the likely influence of this feedback in the present transition to a warmer climate.
Driving a palaeomagnetic revolution: geophysical and environmental signals from magnetic biominerals. Magnetotactic bacteria biomineralise magnetic nanoparticles. They are ubiquitous in aquatic environments, so their inorganic remains (magnetofossils) should give rise to sedimentary palaeomagnetic signals. Ancient magnetofossil identifications were sparse until new techniques recently demonstrated their extensive geological occurrence. This project proposes to determine: the mechanisms by which ....Driving a palaeomagnetic revolution: geophysical and environmental signals from magnetic biominerals. Magnetotactic bacteria biomineralise magnetic nanoparticles. They are ubiquitous in aquatic environments, so their inorganic remains (magnetofossils) should give rise to sedimentary palaeomagnetic signals. Ancient magnetofossil identifications were sparse until new techniques recently demonstrated their extensive geological occurrence. This project proposes to determine: the mechanisms by which magnetofossils contribute to sedimentary palaeomagnetic signals; if magnetofossil occurrences provide information about the marine carbon cycle; and, if magnetofossil chemistry can constrain the depth of sedimentary palaeomagnetic signal acquisition. These are major outstanding questions in sedimentary palaeomagnetism.Read moreRead less
The Limits of maritime jurisdiction: overcoming uncertainties and safeguarding Australia's interests. Research on the definition of baselines along Australia's long, complex and dynamic coastline will assist in the stable definition of the limits of its vast maritime claims. Allied to research on key oceans governance and maritime security challenges, the research will help to safeguard Australia's significant and growing marine resource interests.
