How the complexity of continental breakup controls ocean circulation. This project aims to address the evolution of oceanic seaways formed during separation of tectonic plates (such as Australia and Antarctica). The seaways that form are key components modulating the global ocean circulation system and are implicated in major glacial expansion events.

This project aims to address the evolution of oceanic seaways formed during separation of tectonic plates (such as Australia and Antarctica). The seaways that form are key components modulating the global ocean circulation system and are implicated in major glacial expansion events. This project aims to unravel their role relative to other drivers for example carbon dioxide (CO2). Unravelling the influence of seaway opening compared with declining CO2 in the onset of Antarctic and Northern hemisphere glaciation will enable more accurate future climate simulations. The project will also give international exposure and training to the next generation of numerically adept geoscientists and oceanographers.Read moreRead less
Pyrite: a deep-time capsule of ocean chemistry and atmosphere oxidation. Surprisingly little is known about trace element trends in past oceans, even though these data are vital for interpreting the evolution of the Earth's atmosphere, evolutionary pathways of marine life and cycles of major mineral deposits. Using laser-based analysis of sedimentary pyrite in deep marine rocks, this project aims to produce, for the first time, temporal variation curves for 25 trace elements in seawater over the ....Pyrite: a deep-time capsule of ocean chemistry and atmosphere oxidation. Surprisingly little is known about trace element trends in past oceans, even though these data are vital for interpreting the evolution of the Earth's atmosphere, evolutionary pathways of marine life and cycles of major mineral deposits. Using laser-based analysis of sedimentary pyrite in deep marine rocks, this project aims to produce, for the first time, temporal variation curves for 25 trace elements in seawater over the last 3.5 billion years. Preliminary research has validated the technique and demonstrated major changes in certain trace elements over geologically short periods. Outcomes will assist the minerals industry in the discovery of new deposits of zinc, copper, gold and iron ore in Australia.Read moreRead less

Summary
Deep-sea magnetics: a key tool for enhanced 4D hydrothermal exploration. This project aims to constrain the magnetic response and detectability of mantle and hotspot-related vents. Deep-sea hydrothermal systems are oases of unique life and are considered as the most valuable scientific and mining targets ever discovered in the oceans. The project is expected to enable a better understanding of these enigmatic features, in both their active and inactive phases. It will use new and highly powerful ....Deep-sea magnetics: a key tool for enhanced 4D hydrothermal exploration. This project aims to constrain the magnetic response and detectability of mantle and hotspot-related vents. Deep-sea hydrothermal systems are oases of unique life and are considered as the most valuable scientific and mining targets ever discovered in the oceans. The project is expected to enable a better understanding of these enigmatic features, in both their active and inactive phases. It will use new and highly powerful processing methods on existing data and on data collected off the Tasmanian continental shelf. The project is expected to unveil the characteristics of hydrothermalism in a wide range of contexts and improve Australia’s competitiveness in scientific and mining hydrothermal exploration and to potentially guarantee the supply of raw materials for future generations.Read moreRead less

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

Calcification and shell chemistry response of Southern Ocean planktic foraminifers to ocean acidification and changing climates. Plankton that form tiny calcium carbonate shells will be cultured to determine how they will respond to acidification of the Southern Ocean caused by rising CO2 in the atmosphere. The same experiments will be used to gauge from their fossil shells how the Southern Ocean has caused and responded to changing atmosphere CO2 over the last glacial climate cycle

Resolving the warming East Australian Current's impact on a marine food web. This project aims to understand the effects of climate change on marine food webs, from plankton production to predation by iconic marine fauna, by integrating data on oceanographic conditions and fish distribution with the foraging patterns and breeding success of seabirds. Warming waters due to strengthening western boundary currents have unknown consequences for coastal marine food webs. Innovative prey capture signatures from accelerometers, and advanced movement models from satellite locations will show how predators locate and prey upon fish schools. Anticipated outcomes are insight into how changing resource availability in the oceans affects ecosystem resilience; improved viability for coastal industries; and ecosystem-based conservation management strategies.Read moreRead less
Using animal-borne cameras to quantify prey field, habitat characteristics and foraging success in a marine top predator. To understand the factors which influence population dynamics, knowledge of habitat use is required. This project will determine the key ecological characteristics of the Australian fur seal habitat, enabling fundamental issues of foraging ecology and wildlife management to be addressed for the first time in a marine mammal.

This multidisciplinary proposal has four integrated research themes which enhance existing Antarctic research. The proposal will build new polar research capability in Tasmania to secure and reinforce its recognition as a global leader in Antarctic and Southern Ocean science; develop a marine technology hub; leverage co-investment with national and overseas agencies; and further establish Tasmania as a gateway for Antarctic research, education, innovation and logistics. The initiative will bolster Australia's Antarctic program via integration of novel understanding of ice-shelf and ice sheet contributions to present-day sea level change, and new perspectives on polar marine ecosystems and biogeochemical cycles, and sea-ice forecasting.Read moreRead less

Developing solutions to marine mammal interactions with long-line fisheries. This project aims to use innovative techniques to determine aspects of natural marine mammal behaviour that can be exploited, in conjunction with optimal fishing vessel operations, to minimise their interactions with commercial fisheries. Marine mammal interactions with commercial fisheries are a growing worldwide issue with both ecological (incidental bycatch and increased dependence on fisheries) and economic consequences (annual losses of tens of millions of dollars to the fishing industry). Successful solutions to reduce these interactions have remained elusive. Outcomes from this research are expected to be applicable worldwide, have substantial economic and ecological benefits, and ensure the sustainability of the fishing industry.Read moreRead less
