The Australian Synchrotron has been used by our researchers to answer questions about our geological history and help us understand processes on other planets.
Researchers have used the Synchrotron to rapidly assess the processes and nature of volcanic eruptions, and learn about our past climate to help predict what might happen in future.
These are a few of New Zealand researcher' contributions to better understanding of planetary processes.
How hot springs can help us find life on Mars >> The possibility of life on Mars has fascinated lay people and scientists for decades. Analysis of sinter samples from hydrothermal systems in Chile and New Zealand together with samples from ancient sinter deposits revealed biostructures associated with life. Biosignatures from Martian samples would be detectable with current techniques, which would represent a significant scientific milestone.
A new process discovered in deep submarine volcanic eruptions >> In July 2012, the submarine Havre Volcano quietly erupted, generating a massive pumice raft. The study was the first to use the FTIR imaging to investigate water speciation in volcanic ash in detail. It highlighted a previously unknown process and showcased the potential of the technique to better understand this newly identified phenomenon.
Rapid assessment of pumice from the 2022 Tonga volcanic eruption assists disaster response efforts >> The Hunga-Tonga-Hunga-Ha'apai eruption was the largest in more than 30 years. Rapid assessment of samples using the Imaging and Medical beamline found that the small particles ejected were a hazard to helicopter flight and people. As well as scientific value, the team were able to relay the hazard information to assist disaster agencies.
South Pacific cave formations help understand past climate and predict future changes >> Like ice cores, cave stalagmites and stalactites are an archive of climate history. The researchers found a new way to reconstruct historical climate changes from formations from Niue and the Cook Islands, which helps improve our understanding of how the region’s climate might respond in future.
