Indian Ocean Climate Change: Ningaloo Reef, a litmus test for the survival of coral reefs. Coral reefs are at the frontline from the effects of rapidly rising levels of carbon dioxide that is causing both global warming and oceans to become more acid-like. Our research program will determine how the survival of one of the World’s most pristine and best preserved coral reefs, Ningaloo Reef, is linked to the response of Australia’s Indian Ocean to climate change. For the first time, we will simula ....Indian Ocean Climate Change: Ningaloo Reef, a litmus test for the survival of coral reefs. Coral reefs are at the frontline from the effects of rapidly rising levels of carbon dioxide that is causing both global warming and oceans to become more acid-like. Our research program will determine how the survival of one of the World’s most pristine and best preserved coral reefs, Ningaloo Reef, is linked to the response of Australia’s Indian Ocean to climate change. For the first time, we will simulate realistic ‘future’ conditions and see how actual coral reef systems respond. This will provide a ‘yardstick’ against which the best-case survival potential of the world’s coral reefs can be assessed, critical for underpinning the urgently needed action to reduce greenhouse gas emissions if we are to ensure the survival of coral reefs.Read moreRead less

How the Earth works - toward building a new tectonic paradigm: This fellowship project aims to build on the latest technological and conceptual advances to establish the patterns of Earth evolution, and use this information to examine a ground-breaking geodynamic hypothesis which links cyclic plate aggregation and dispersion to deep Earth processes. Half a century after the inception of plate tectonics theory, we are still unsure how the Earth 'engine' works, particularly the forces that drive plate tectonics. The project involves extensive national and international collaboration to potentially create a paradigm shift in our understanding of global tectonics, and hopes to contribute to an understanding of the formation and distribution of Earth resources to provide a conceptual framework for their exploration.Read moreRead less
The Social Production of Science in Antarctica: A Study of Davis Station. Antarctica is a unique scientific laboratory. It is the only continent historically uninhabited by humans; access to its vast land and ice-scapes, and its surrounding oceans, is today almost exclusively reserved for scientists. Although these 'Antarcticans' represent multiple disciplines, and pursue a wide variety of research agendas, their shared experiences of working on the continent, and their shared professional netwo ....The Social Production of Science in Antarctica: A Study of Davis Station. Antarctica is a unique scientific laboratory. It is the only continent historically uninhabited by humans; access to its vast land and ice-scapes, and its surrounding oceans, is today almost exclusively reserved for scientists. Although these 'Antarcticans' represent multiple disciplines, and pursue a wide variety of research agendas, their shared experiences of working on the continent, and their shared professional networks, mean that they constitute a distinct community of practice. However, this community has yet to be subjected to detailed ethnographic enquiry. This project aims to examine Antarctic scientists' research practices, and their cultures of knowledge production, through an ethnographic study of Australia's Davis Station.Read moreRead less

This project aims to use land surface radiation management to reduce the intensity of heat waves. Heat waves have high social, environmental, and economic effects, and their intensity will increase. Using climate models, this project will examine how altering current land management practices could change properties of soils and vegetation to reduce the intensity of heat waves. The expected outcomes of this project are information on adaptation to the increasing intensity of heat waves in Australia, which will be applicable globally.Read moreRead less
Revealing the impacts of super-charged photosynthesis on leaf respiration. This project aims to use state-of-the-art technologies to develop a novel framework that links a super-charged version of photosynthesis (known as C4 photosynthesis) to changes in nocturnal leaf respiration. A quarter of global land photosynthesis occurs in C4 plants that include several important cereal crops. Although advances have been made in modelling C4 photosynthesis, these advances are unable to model variations i ....Revealing the impacts of super-charged photosynthesis on leaf respiration. This project aims to use state-of-the-art technologies to develop a novel framework that links a super-charged version of photosynthesis (known as C4 photosynthesis) to changes in nocturnal leaf respiration. A quarter of global land photosynthesis occurs in C4 plants that include several important cereal crops. Although advances have been made in modelling C4 photosynthesis, these advances are unable to model variations in nocturnal respiration. Expected outcomes include equations that predict respiration in C4 plants growing in current/future climates. Benefits to include knowledge needed to engineer faster-growing crops and providing climate modelers the ability to more accurately predict carbon exchange in C4-dominated ecosystems.

Quantifying and parameterising ocean mixing. This project aims to advance our ability to describe the efficiency and intensity of ocean mixing. The project will develop and apply innovative techniques to estimate ocean mixing from both traditional ship-based, vertical-profiling turbulence measurements and from autonomous moorings. The project will undertake a re-analysis of historic measurements and obtain new measurements using autonomous systems. The results will be used to develop both a uni ....Quantifying and parameterising ocean mixing. This project aims to advance our ability to describe the efficiency and intensity of ocean mixing. The project will develop and apply innovative techniques to estimate ocean mixing from both traditional ship-based, vertical-profiling turbulence measurements and from autonomous moorings. The project will undertake a re-analysis of historic measurements and obtain new measurements using autonomous systems. The results will be used to develop both a universal relationship describing the efficiency of ocean mixing, and to quantify the underlying length scale controlling mixing intensity. This will enable the development of the next generation of turbulence closure models needed to describe ocean circulation and stirring.Read moreRead less
Annual rainfall variability and extreme drought over the late Holocene. This project aims to understand long-term rainfall variability for Australia by developing a network of extended, high resolution rainfall records from tree rings.

This project aims to understand long-term rainfall variability for Australia by developing a network of extended, high resolution rainfall records from tree rings. How anthropogenic changes to the atmosphere have influenced changing rainfall patterns across Australia is unclear. By extracting climatic information from tree growth rings across a latitudinal gradient from the subtropical north to the south coast of western Australia, the project will extend hydroclimatic records by several centuries, to identify the frequency and extent of extreme droughts across the continent. Outcomes are expected to provide appropriate context for evaluating and adapting to climate change, allowing climate modellers, agricultural producers and other industries to improve forecasts of likely change for risk management.Read moreRead less

Dating Murujuga's Rock Art: new scientific approaches. The Dampier Archipelago is on Australia's National Heritage List because of its significant rock art and stone features. Known as Murujuga to its traditional custodians, this land- and seascape has over 1 million art works. While the scientific and cultural significance of this area is acknowledged, we still know little about the age of this landscape, the regional palaeoclimatology, and the timing and intensity of rock art production since ....Dating Murujuga's Rock Art: new scientific approaches. The Dampier Archipelago is on Australia's National Heritage List because of its significant rock art and stone features. Known as Murujuga to its traditional custodians, this land- and seascape has over 1 million art works. While the scientific and cultural significance of this area is acknowledged, we still know little about the age of this landscape, the regional palaeoclimatology, and the timing and intensity of rock art production since Aboriginal people moved into this region 50,000 years ago. This project will develop new scientific approaches to direct-dating engravings and stone features, reconstruct climate from geological proxies, and model voyaging opportunities as this unique cultural estate transformed to an archipelago.Read moreRead less
Building Central Asia: Linking the Growth of Asia to its Exhumation. The consumption of the Tethys Ocean and the associated collision of Gondwana-derived terranes with Eurasia resulted in the uplift of the highest mountain belt on Earth: the Himalayas. However, stresses from this collision zone propagated far into the Eurasian interior by reactivating faults and creating mountain belts along these fault zones. This project aims to map and model how and when fault (re)activation occurred by integ ....Building Central Asia: Linking the Growth of Asia to its Exhumation. The consumption of the Tethys Ocean and the associated collision of Gondwana-derived terranes with Eurasia resulted in the uplift of the highest mountain belt on Earth: the Himalayas. However, stresses from this collision zone propagated far into the Eurasian interior by reactivating faults and creating mountain belts along these fault zones. This project aims to map and model how and when fault (re)activation occurred by integrating multi-method thermochronological and structural data on major Meso-Cenozoic Central Asian fault systems. The resulting time-integrated tectonic model will aid in the understanding of the India-Eurasia collision, the building of the mountainous Central Asian landscape and its influence on the Asian climate.Read moreRead less
