Quantifying the Tree of Life's Diversity with the Paleobiology Database. The Paleobiology Database is the Internet's key source of scientific data on the fossil record. It records names and classification of fossil organisms and the ages, locations, and environments of the places that yield these fossils. It has often been used to estimate the number of species existing at different points in geological time. Macquarie will house the Database as it is expanded to record evolutionary relations ....Quantifying the Tree of Life's Diversity with the Paleobiology Database. The Paleobiology Database is the Internet's key source of scientific data on the fossil record. It records names and classification of fossil organisms and the ages, locations, and environments of the places that yield these fossils. It has often been used to estimate the number of species existing at different points in geological time. Macquarie will house the Database as it is expanded to record evolutionary relationships of many species. This information will help to estimate dates of origination for major groups such as mammals and birds. It will also help to show whether mass extinctions tend to target old groups with few surviving species, which will help to predict which groups will survive the current mass extinction.Read moreRead less
Redox conditions in the earth's upper mantle and the implications for kimberlite petrogenesis, diamond formation and mantle metasomatism. Diamonds are an important and high value commodity. Australia is the world's leading producer in terms of carats, due mainly to the massive Argyle deposit in northern Western Australia. Although diamonds form at great depths in the earth, they are accessible at the surface because they are transported by rare volcanic rocks, kimberlites and lamproites. Despite ....Redox conditions in the earth's upper mantle and the implications for kimberlite petrogenesis, diamond formation and mantle metasomatism. Diamonds are an important and high value commodity. Australia is the world's leading producer in terms of carats, due mainly to the massive Argyle deposit in northern Western Australia. Although diamonds form at great depths in the earth, they are accessible at the surface because they are transported by rare volcanic rocks, kimberlites and lamproites. Despite their importance the genesis of these rocks is poorly understood. This research will address this, providing scientific constraints on models for formation of diamonds and their host volcanics, which will directly inform the minerals industry's exploration models. There will be an economic benefit to the nation in terms of more successful outcomes from exploration expenditure.Read moreRead less
Stochastic Methods in Mathematical Geophysical Fluid Dynamics. The project will develop analytical and numerical methods for long-term weather forecasting and climate modelling. The project deals with the mathematical aspects and fundamental mechanisms underpinning numerical climate forecasting. The project will develop new methodology for accurate modelling of the important and dominant slow global processes without explicitly resolving the precise detail of the weather of each day at all scale ....Stochastic Methods in Mathematical Geophysical Fluid Dynamics. The project will develop analytical and numerical methods for long-term weather forecasting and climate modelling. The project deals with the mathematical aspects and fundamental mechanisms underpinning numerical climate forecasting. The project will develop new methodology for accurate modelling of the important and dominant slow global processes without explicitly resolving the precise detail of the weather of each day at all scales. Using sophisticated mathematics, this project investigates how to parameterize the fast and small processes by using stochastic processes in a controllable and adaptive way.Read moreRead less
