This project aims to unravel the biogeochemistry of vanadium in modern marine sediments for use as a tracer of ancient oxygen concentrations in the oceans of the early Earth. This project will generate fundamental knowledge on the behaviour of vanadium in modern marine sediments by applying advanced analytical tools for imaging its concentration and chemical form at ultra-high resolution. This information is critical for accurate interpretation of the geological record to infer the oxygen concentration of the oceans at various points in Earth's history. This interdisciplinary project will facilitate strong collaboration between Australian and Danish researchers in the field of marine geochemistry and paleoceanography.Read moreRead less
Geomorphological development of coral reefs, southern Great Barrier Reef: an integrated record of Holocene palaeoecology and palaeoclimate from cores. Very little is known about how the Great Barrier Reef (GBR) has responded or may respond to predicted environmental change and/or degradation. The project will reconstruct the recent biological and physical history of reefs in the southern GBR in order to better understand how they may react to future environmental changes.
Mantle evolution and the origin of Earth's atmosphere. This project aims to investigate Earth’s early evolution and the origin of our atmosphere. Using state-of-the-art instrumentation the project will measure noble gas and tungsten isotopes in unique volcanic glasses that record the composition of the Earth’s mantle. These measurements are expected to clarify the relationship between the formation of Earth’s atmosphere, mantle and core, and to generate new knowledge about convective currents ....Mantle evolution and the origin of Earth's atmosphere. This project aims to investigate Earth’s early evolution and the origin of our atmosphere. Using state-of-the-art instrumentation the project will measure noble gas and tungsten isotopes in unique volcanic glasses that record the composition of the Earth’s mantle. These measurements are expected to clarify the relationship between the formation of Earth’s atmosphere, mantle and core, and to generate new knowledge about convective currents in the modern mantle. The project aims to train the next generation of Earth scientists and to provide new knowledge to assist in overcoming the challenges in mitigating climate change and sustaining a resource-based economy.Read moreRead less
Understanding marine migratory connectivity for more sustainable oceans. Ocean basin-scale migrations of iconic sea turtles, marine mammals, seabirds, and fish expose them to multiple stressors and governance regimes, leading to gaps in management and population declines. The project aims to deliver the methods and evidence base of cross-taxa migratory connectivity that is essential to support the
conservation of these species. Expected outcomes include comprehensive and integrated models of mig ....Understanding marine migratory connectivity for more sustainable oceans. Ocean basin-scale migrations of iconic sea turtles, marine mammals, seabirds, and fish expose them to multiple stressors and governance regimes, leading to gaps in management and population declines. The project aims to deliver the methods and evidence base of cross-taxa migratory connectivity that is essential to support the
conservation of these species. Expected outcomes include comprehensive and integrated models of migratory connectivity, conservation theory development, and new methods that allow incorporation of migratory connectivity in conservation planning. Benefits include: a cross-taxa baseline that will enable Australia to measure environmental change in marine migratory connectivity for the first time.Read moreRead less
An elemental hypothesis for sub-tropical refugia in reef corals. This project aims to discover the underlying traits that permit Australian reef corals to live near the edges of their ranges in relatively cool water. As ocean temperatures warm, novel communities are expected to develop in high latitude ecosystems, which might become important as thermal refugia for low latitude coral reefs. The project aims to test the role of elemental composition (carbon, nitrogen and phosphorus) in coral host ....An elemental hypothesis for sub-tropical refugia in reef corals. This project aims to discover the underlying traits that permit Australian reef corals to live near the edges of their ranges in relatively cool water. As ocean temperatures warm, novel communities are expected to develop in high latitude ecosystems, which might become important as thermal refugia for low latitude coral reefs. The project aims to test the role of elemental composition (carbon, nitrogen and phosphorus) in coral host and symbiont response to changing water temperature along a latitudinal gradient. The intended outcome of the project is to provide knowledge to support predictions of likely species migrations from tropical to subtropical waters, enabling managers to anticipate the future response of coral communities to seawater warming.Read moreRead less
Microscale insights into ocean-scale processes: microbial behaviour as a driver of ocean biogeochemistry. Microscopic plankton regulate the ocean's chemical cycles, which ultimately support life on earth. However, the ecological interactions driving these processes are poorly understood. This project will use novel approaches to decipher the behaviours of marine microbes, providing a more complete perception of how ocean ecosystems operate and influence climate.
Orientation in the pelagic environment: how do larval marine fish find their way home? This study will determine what senses tiny fish larvae use to orientate in the ocean and to influence where currents disperse them. Because larval dispersal determines the spatial extent of fish populations, this knowledge is important for management of marine fisheries and the design and operation of marine parks.
How sponges and bacteria maintain productivity on coral reefs. This project aims to listen in on conversations between a Great Barrier Reef sponge and its bacterial symbionts. Coral reefs thrive in nutrient-poor tropical seas by efficiently retaining and recycling essential elements. Marine sponges help coral reefs by co-operating with metabolically diverse bacterial symbionts via largely unknown mechanisms. Using an advanced genome-enabled sponge, invertebrate biology, microbiology, genomics an ....How sponges and bacteria maintain productivity on coral reefs. This project aims to listen in on conversations between a Great Barrier Reef sponge and its bacterial symbionts. Coral reefs thrive in nutrient-poor tropical seas by efficiently retaining and recycling essential elements. Marine sponges help coral reefs by co-operating with metabolically diverse bacterial symbionts via largely unknown mechanisms. Using an advanced genome-enabled sponge, invertebrate biology, microbiology, genomics and metabolomics, this project seeks to reveal genomic and metabolic details of the partnership, which could inform environmental restoration, pharmaceuticals and biotechnology.Read moreRead less
Climate change impacts on latitudinal diversity gradients in reef corals. This project will investigate the consequences of a warmer ocean that occurred during past intervals of global climate change on the latitudinal distribution of reef-building corals. This work will provide managers and industry with critical insight into the effects of ongoing climate change on the biodiversity and biogeography of living coral reefs.
Habitat degradation on coral reefs. This project aims to determine how reef degradation modifies predator-prey dynamics in fish communities, and how parental effects may help species to cope with habitat change. Live corals are ecosystem engineers that support the world’s most biodiverse communities, but anthropogenic factors have led to unprecedented global declines in live coral. The transition from live to dead coral-dominated habitats is associated with a modified sensory landscape of fear f ....Habitat degradation on coral reefs. This project aims to determine how reef degradation modifies predator-prey dynamics in fish communities, and how parental effects may help species to cope with habitat change. Live corals are ecosystem engineers that support the world’s most biodiverse communities, but anthropogenic factors have led to unprecedented global declines in live coral. The transition from live to dead coral-dominated habitats is associated with a modified sensory landscape of fear for resident fishes, via chemical interference emanating from degraded coral. Inter-generational advantages would help management to regulate reef usage to promote resilience.Read moreRead less
