Proposed cuts at #ANSTO look very likely to affect the Australian Quaternary community - worryingly via ceasing expert support for 14C dating. I wonder what proportion of Australian quaternarists have leaned on ANSTO facilities? I'm going to guess all of us!
There is still oportunity to make comment, more details in this quite hidden press release:

#ANSTO is advertising an ongoing position on the MX beamline at the Australian Synchrotron, looking for a chemical crystallographer to join the team.
I've no experience on MX, but in general the beamline scientists at the Aussietron seem to have a good time? Should be a great experience!

Historical holes: Beneath the surface, caves hold the key to Australia’s wildfire history
My colleague @michcampbell recently held a postdoctoral research grant from AINSE. They've just released this 2025 Research Spotlight for early career researcher awardees all about her fire research. I think this is nicely done. If you'd like to know how caves and cave stalagmites can be used to reconstruct records of past fires, here's the article

Just published in Organic Geochemistry, "Fire-induced shifts in stalagmite organic matter mapped using Synchrotron infrared microspectroscopy", led by #ANSTO colleague Dr. Liza McDonough. We demonstrate for the first time that Synchrotron IRM is a promising non-destructive, high resolution (5 µm) technique for analysing stalagmite organic matter. The paper can be found #OpenAccess here: https://doi.org/10.1016/j.orggeochem.2024.104842

The things that dissolve out of wildfire ash
A few weeks ago my colleague @michcampbell published a paper all about this. As the title states, combustion completeness and sample location determine wildfire ash leachate chemistry. So what is that chemistry? Lets start with the story of the paper. After the 2019/2020 Australian wildfires, there was a lot of wildfire ash on the landscape.

Paper publication day is one of my favourite days! Our paper on wildfire ash chemistry is out today and #OpenAccess in the #AGU journal 'Geochemistry, Geophysics, Geosystems.' We analysed the inorganic and organic chemistry of wildfire (and prescribed burn) ashes from 4 karst areas in Australia and found that ash chemistry varies with burn severity and sampling location. Another team effort from #ANSTO, #UNSW, #UWA, #GNSScience colleagues (👋 @Andbaker )

If you are interested in the chemical tracers of wildfires, and how those might vary with burn severity, check out our new #preprint https://www.authorea.com/doi/full/10.22541/au.170689252.26414470/v1
We leached wildfire ashes and soils from karst areas, so we can better understand the speleothem palaeofire proxy signal. Another team effort, with co-authors from #UNSW (👋 @Andbaker) #ANSTO, #UWA, and #GNSScience

Thank you to Bernadette Zanet and her team at Yarrangobilly Caves for supporting another fruitful research visit this week.
UNSW alumnus and data analyst Rebecca Chapman returned to explain all about her research on the hydrology at the Harrie Wood Cave. Her novel application of a statistical method called 'functional data analysis' has been submitted for publication, and there is a pre-print available here:
https://lnkd.in/gX6iSGz9We welcome all comments and feedback.
I had the opportunity to download the latest hydrology data from the caves, now a 12-year record of water movement from the surface to the groundwater. And also help out with some questions on cave climate monitoring. And catch some wonderful views.
The pre-print is "Spatiotemporal Variation in Cave Percolation Waters: A Functional Approach" with co-authors Shawn Laffan (UNSW), Monika Markowska (MPIC) and Liza McDonough (ANSTO) and is another collaboration between UNSW and ANSTO.

Congratulations to my groundwater friends and colleagues at ANSTO, who appear to have swept the boards at their award night.
ANSTO is Australia's nuclear science organization, running a research reactor to generate isotopes used in the health sector.
And they have an environmental isotopes team, which is where I collaborate. So: congratulations to Dr Karina Meredith (Excellence in Research), Liza McDonough (early-mid career award) and all of the groundwater team

Over the last few years, we (Pauline Treble, @michcampbell, Liza McDonough, @unsw and ANSTO) have been establishing a new methodology to obtain records of fire history. It uses cave stalagmites as the archive of past fires, a novel approach for cave science and fire research communities.
Why use cave stalagmites to record fire history? They can contain exceptionally long and continuous annual laminae that allow us to count back in time very precisely. And this allows the precise determination of fire frequency in the past, which is measured using high-resolution geochemical techniques such as laser ablation mass spectrometry and synchrotron elemental mapping.
Next week, Liza, Micha and Pauline present our most recent results at the EGU General Assembly in Vienna. If you are interested, the abstracts are accessible to everyone using the links below.

Are you interested in fire history, and novel methods for obtaining records of past fires.
At the EGU General Assembly in April 2023, please consider attending the session "Novel proxies for understanding past fires: outcomes for land and ecosystem management".
My colleague @michcampbell is co-convening and she'd love to see you there!
EGU23 will be fully hybrid, and she welcomes submissions from online attendants.

Next week we have a poster of our latest research at the American Geophysical Union Fall Meeting (#AGU22).
What are we presenting about? Our use of stalagmites as archives of past fires
Why use stalagmites? They have a very high resolution, meaning that we can count annual growth layers and identify the frequency of fires in the past.
How do we do it? We detect the ash-derived elements that are transported from the surface to the cave in drip waters
And the poster? Is about how the oxygen and carbon isotope composition of stalagmites is also affected by fires
For anyone interested, here's the session details:
Quantifying the fire imprint in speleothem oxygen and carbon isotope records
Final Paper Number: PP25C-0894
Tuesday, December 13th; 2:45 PM - 6:15 PM (Chicago time)
Location: online iPoster and Zoom linkThere's a copy of the poster below.
