New paper for the palaeofire fans!
Presenting the SahulCHAR collection, containing 687 sedimentary charcoal records from across Australia, New Guinea, and Aotearoa/New Zealand π₯
Read it open access here: https://doi.org/10.5194/essd-17-2681-2025
This is the product of my final postdoc role - thank you to the many generous researchers who contributed their data!
Dear #EGU25 attendees, please consider going along to our session, "CL1.2.12 Understanding carbon cycle β climate interactions during the Quaternary through the study of oceanic circulation, vegetation, and wildfire", which is taking place on Friday.

I'm very pleased to be co-convening this proposed session at #EGU25 with @Geo_Juv and others - "CL1.2.12
Using proxy data, observations, and modeling to understand vegetation-wildfire-climate interactions during the past, present, and future." We look forward to your submissions, and catching up in Vienna!
Box of rocks arrived for me today π we will be taking these beauties to the Aus Synchrotron next month to get an idea if they might be suitable for #palaeofire research. Happily, these were collected by a friend of mine for her PhD, which means a potential collaboration with a friend (yay!), and the reuse of old samples rather than collecting new (double yay!).
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 (π @Andbaker) #ANSTO, #UWA, and #GNSScience

The good folk at ANSTO did a nice summary of our speleothem palaeofire project over on Insta! Apparently, they did it last May, and I totally missed it π€¦π»ββοΈ

#ArtAdventCalendar - one of my paintings features on the cover of a science-art journal, just released! It shows palaeoecology as an Australian landscape made up of fragments of time

#ArtAdventCalendar - a selection of drawings from my Charcoal in Charcoal series. These are charcoal drawings of some of the magnified fossil charcoal particles I studied from the lake cores in my PhD, to reconstruct ancient fire histories
Some of these are 8,000 years old!
With perfect timing for #CharcoalTuesday, I just came across this great overview of charcoal analyses (and why we do them) by Fleur King et al.
It gives a brief look at #palaeofire and goes into some depth on #anthracology! π₯
This paper was included in the 11th issue of Excavations, Surveys and Heritage Management in Victoria and was presented at the annual Victorian Archaeology Colloquium (held on-line) by La Trobe University on 4 February 2022.
We were very kindly invited to write a communication piece for #AGUPubs Eos magazine, to go along with our recent review paper. If you'd like a quick overview on using #speleothems for #palaeofire research, look no further!
