The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

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
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
