Kicking off my research journey at the #WesternGroundwaterCongress 2025 in San Diego! As a geographer at @isoewikom I’m diving into the state’s water challenges—especially the #SGMA process.
For Europe, there’s much to learn as we rethink #water management post-2027: funding mechanisms & stakeholder engagement stand out.
Next stop: UC-Davis as a Visiting Scholar to explore water-agriculture links. Excited to connect & share insights #WFD #Groundwater #Sustainability #CaliforniaWater #WaterPolicy

Why #windfarms attract so much #misinformation and #conspiracytheory
If you think #climatechange is a #hoax, you might believe #windturbines poison #groundwater.
Although we’ve known about #climate change from #carbondioxide as since at least 1950s, early arguments for #renewables tended to be seen more as a way of breaking stranglehold of #fossilfuel companies.
Meanwhile, advocates of renewables—especially wind—often found it difficult to build public support for wind.

"Madison Boyle with the Amarillo Minority Coalition questioned the use of #groundwater for the data center, stating, 'Why are we using ground water that farmers could be using for agriculture, for AI data center, where it's going to deplete a resource that's not really renewable?'
"Boyle highlighted the strain on the #OgallalaAquifer, which is already depleting. Protest organizers urged city officials to consider future generations.
"Amarillo citizen Ashlyn Major called for transparency and suggested a public vote on the project. Fermi America has not responded to interview requests, but former Gov. #RickPerry, now vice president of #FermiAmerica, previously downplayed water concerns, emphasizing water recycling efforts."

Decade of Research in Macleay Caves: Key Findings and Future Directions
Around a decade ago, thanks to a government committee that I was a member of, I was encouraged to consider improving our understanding of the caves and karst in the Macleay karst region of Australia*.
*Roughly midway between Sydney and Brisbane on the east coast of Australia.
That led to me to working with the Kempsey Speleological Society (KSS) members, the local experts on the caves and karst. Some of the KSS designed some climate and hydrology monitoring projects that they were interested in, to know more about the caves and karst in the region. The KSS Cave Studies Team was born.
Forward on over a decade… the KSS has become ‘my’ caving club. A decade ago, the KSS Cave Studies Team designed sampling programs to understand cave climate, and some of the complex hydrology of the Macleay karst. The cave climate research is still unpublished, but yes, we have some very long term climate data.
The first hydrology paper, using drip loggers placed in caves in an altitudinal transect through the Macleay karst, was published in the Journal of Hydrology in 2020, which was interesting for anyone interested in how much rainfall is needed to replenish the groundwater in the regions. But it was only the first step in understanding the karst hydrology in the region.
Which sets the scene for this new pre-print, with the title “Identification of synoptic climate and drought controls on rainfall stable water isotopic composition in the Macleay karst region of eastern Australia”. It is online here and open for community and research comments.
The story of the paper goes something like this…
The KSS desgn their research question a decade ago, and we implemented the monitoring programs to get some answers (hopefully!). Low cost solutions were great, and water stable isotope analyses of spring water samples was one that I proposed as a natural tracer and something that could KI could help with to enable the KSS Cave Studies Team to understand the karst hydrology of the region. That would require grab samples of water from springs and creeks in the region. And rainfall samples to measure the isotopic composition of the ‘input’. The KSS Cave Studies Team were ‘in’!
Please head over to the pre-print to read all about the results, with rainfall isotope data and spring water data from 2017 to 2023. The pre-print has all the formal acknowledgements and research credit statements, but they are quite formal. So here…
I would like to thank Sophia Meehan, without whom, none of this would have happened.
In the KSS, special thanks to Allister Gee for leading the ‘big picture’ monitoring program design.
Philip Holberton, who I never knew as a cave explorer, but I did as a retired former GP and the KSS journal editor, managed monthly IAEA grade water isotope sampling from his property for three years from 2017-2020, including through bushfire evacuations. Vale Philip. He never got to see the results of his meticulous sampling.
Glen Bowman, one of the founding KSS Cave team, who took on the rainfall sampling and went to event sampling from his property from 2020 and is ongoing. Data from his samples through to 2023 are also in the pre-print.
And it is a huge effort to collect the karst spring and creek samples. Thanks to the whole KSS Cave Studies Team for collecting these samples. I have been on many of these club caving trips, and I’ve got to all the sample sites. This is tough, tough country to move through, and at the same time one of the most beautiful landscapes I have have worked in. Thank you to the team for agreeing to pack sample bottles on all those caving expeditions
