Novel tools for dating explosive volcanic eruptions in the critical window. This project will develop novel dating methods necessary for precise reconstruction of the eruption histories of super-volcanoes in the Asia-Pacific region over the last million years. The project outcomes will provide better models for predicting super-eruptions, thereby informing global climate change research, urban planning, and transport and telecommunications infrastructure engineering. Results will also improve ex ....Novel tools for dating explosive volcanic eruptions in the critical window. This project will develop novel dating methods necessary for precise reconstruction of the eruption histories of super-volcanoes in the Asia-Pacific region over the last million years. The project outcomes will provide better models for predicting super-eruptions, thereby informing global climate change research, urban planning, and transport and telecommunications infrastructure engineering. Results will also improve existing volcanic risk models used by insurers to quantify volcanic risks and calculate expected losses from volcanic eruptions, and greatly improve our ability to use eruption deposits as time markers for important events in human evolution.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

Summary
Controls on the severity of past environmental crises. This project aims to investigate how the rate of volcanic volatile emissions controlled the severity of past environmental crises. Catastrophic mass extinctions and major oceanic anoxia events are principally caused by the emplacement of gigantic volcanic eruptions but the volume of magma does not correlate with environmental severity. This project couples high-precision age and volatile emission measurements to model distinct climatic pertu ....Controls on the severity of past environmental crises. This project aims to investigate how the rate of volcanic volatile emissions controlled the severity of past environmental crises. Catastrophic mass extinctions and major oceanic anoxia events are principally caused by the emplacement of gigantic volcanic eruptions but the volume of magma does not correlate with environmental severity. This project couples high-precision age and volatile emission measurements to model distinct climatic perturbations over Earth’s last 540 million years. The intended outcome is to find a root cause for severity of past environmental crises, with past emission rates to be used as tools to model possible future climatic crises and provide a new fundamental understanding of Earth’s magmatic engine.Read moreRead less
