Professor of Earth Science at UNSW Sydney, investigating groundwater, climates, cave science, paleoclimate, geochemistry, organic matter fluorescence, stalagmites. Not all at once, at least not most of the time. Posting more often at @andbaker@aus.social
It's a wrap on our Wellington Caves fieldwork and filming about groundwater recharge. I have some superstar UNSW colleagues, happy to film and be filmed. Looking forward to see how all this looks. Thanks to @marilumelozurita.bsky.social and the

It's starting to look a lot like fieldwork (Wellington Caves and UNSW Research Station edition).

Thanks to the Capricorn Caves team for another amazing research visit.
We downloaded cave hydrology loggers and a groundwater level logger, and ACKMA cave climate loggers. Visited the groundwater recharge zone above the cave. Saw lots of bats, and tree roots deep into the cave system.

It was 'student night' at IAH NSW in Sydney ( and online everywhere).
Thanks to Akhi Kumar, Danyang Sun, Nane Weber and Yaggesh Sharma for presenting their groundwater research.
I might have photobombed the official photo!

Day one of the #IAH2025 Congress and the fieldtrip led by Wendy Timms at the Walhalla Long Tunnel Heritage Gold Mine.
What has this to do with groundwater? Mines like this are observatories of groundwater recharges in action. And we have had loggers in the mine recording when recharge events occur.

Two weeks later, I looked at
Reviewer 2, who seems to have also used a LLM model in their review.
The hyperlinks seem okay, but behind them are references to different papers that have the same authors.
I asked ChatGPT to check for AI use.
That's 2 of 3 reviews with fake reference auggestions.

It's been a privilege present our groundwater hydrology research at the ACKMA2025 conference on cave and karat management at Wellington Caves, Australia.
Even more to be invited to co-lead conference cave tours with Bec Pedemont. Expert delegates ask the tough questions!

Don't be this reviewer, who uses #ChatGPT to show the references that I should have cited, and which are of course fake.
And don't be the editor who let this through as an allowable review.
Calling out publisher IOP and journal Environmental Research Commications.

What a wet #City2Surf!
Luckily, I only got soaked in the final 3km, running ankle deep in stormwater.
And there are not many 'after' photos on socials as our phones (and everything else) were dripping wet.
Anyway, turns out you run faster in the pouring rain 🤔 #running

It was an honour to present to the Ghana Association of Hydrogeologists and the Ghana Institute of Geoscientists this morning. Thank you for the invite!
Hoping for some new collaborations investigating climate and groundwater recharge. This is the amazing flier they designed.

Thursday's office: a cave that has groundwater flooding.
The stalagmites here grow only when the water table is below them.
And have to grow through white calcite ctystals left from the floodwater.
This is how it looks after the 2023 floods.

Thanks to Dubbo Regional Council for hosting us again at Wellington Caves, Australia.
We'll be underground, continuing our investigation of caves as observatories of groundwater recharge.
In the meantime, this is Dippy the diprotodon.

Result! When a large part of your eucalyptus tree comes down and misses all power lines and your neighbours parked cars and can moved off the road with some brute force before emergency services arrive.

#AMOS2025 Day 3. I've been learning about compound weather events, extreme rainfall, & how climate drivers influences on rainfall.
Why?
agupubs.onlinelibrary.wiley.com/doi/full/10....
You need top 10% rainfall events for rain to reach the groundwater.
Find out more today in the final session.

Another Willi Willi fieldwork is successfully completed, and the caves are as photogenic as ever. This is one of our long term climate and groundwater #hydrology monitoring site, now in its 12th year of data, only possible due to the 'citizen science' of Kempsey Speleo Soc members & support of NPWS.

150 mm overnight here on the NSW Central coast, on top of around 120 mm the last few days. Sadly there is major flooding. This weather is only good for rain gauges
