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.

Investigation of the early history of the moon. The project will address outstanding questions related to the early evolution of planets in the solar system, including the earth, by investigating major events that took place on the moon, where the record of early history is preserved exceptionally well. It will test major models describing the chemical evolution of both the moon and earth.

Summary
Ultra-precise dating in Earth, planetary and archaeological science. An advanced facility incorporating next generation, multi-collector mass spectrometer and ultra-clean gas line systems, capable of ultra-precise dating of Earth, planetary and archaeological material. This joint Melbourne-Curtin facility seeks to generate ultra-precise age data from ever smaller and younger samples, such as minute particles from space return missions and tiny inclusions in diamonds. The facility is expected to ....Ultra-precise dating in Earth, planetary and archaeological science. An advanced facility incorporating next generation, multi-collector mass spectrometer and ultra-clean gas line systems, capable of ultra-precise dating of Earth, planetary and archaeological material. This joint Melbourne-Curtin facility seeks to generate ultra-precise age data from ever smaller and younger samples, such as minute particles from space return missions and tiny inclusions in diamonds. The facility is expected to revolutionise noble gas dating techniques, resulting in new knowledge on solar system genesis, hominid evolution, indigenous migrations, palaeo-climate change, natural hazards and ore deposit formation, while further enhancing Australia’s international leadership and competitive advantage in the discipline.

Consequences of extraterrestrial impacts on the biosphere and geosphere. This project will investigate whether high-velocity meteorite impacts can account for the Earth's mass extinctions and whether meteorite impacts and mass extinctions were synchronous. This work will help scientists understand the long-term climatic and biologic effects of massive injections of greenhouse gases into the atmosphere.
Nanoscale repositories of the geological record of Earth and other planets. Rhenium-Osmium (Re-Os) dating is used widely to infer Earth's evolution, but most samples are hydrated, with consequent mobility of Re, which is problematic for interpretation of isotope results. This project will solve this problem by determining the effects of hydration on Re and Os. Further, our knowledge of the mobility of Re and related elements will allow us to recognise rocks that once interacted with water, even ....Nanoscale repositories of the geological record of Earth and other planets.

This project will solve this problem by determining the effects of hydration on Re and Os. Further, our knowledge of the mobility of Re and related elements will allow us to recognise rocks that once interacted with water, even after that water has gone, providing a tool to read the record of Earth's earliest oceans. Our new methods will enable Re-Os dating with clarity and confidence, with profound implications for understanding of Earth and extra-terrestrial planetary evolution.Read moreRead less
