Subaqueous speleothems as archives of groundwater recharge on Australia's southern arid margin Abstract. As anthropogenic climate change enhances aridity across many regions of the globe, understanding drivers of aridification is more important than ever before. Unfortunately, arid regions globally tend to exhibit a paucity of palaeoclimate records, and the archives that are available typically comprise unconsolidated sediments prone to reworking, large dating uncertainties, and ambiguous climatic interpretations. This is certainly true of Australia's vast continental interior, which is dominated by harsh, arid conditions. Mairs Cave, in the southern Ikara-Flinders Ranges (South Australia), is located on the southern margin of the arid zone. In the present day, the cave is largely dry, and there is limited evidence of active speleothem growth. However, historical records and observations throughout the cave indicate that it was periodically flooded, suggesting the local water balance was once much more positive than it is today. The cave contains a curtain of hanging speleothems known as pendulites, which grow subaqueously when submerged in water that is saturated with respect to calcite. Geochemical evidence, including trace element concentrations, uranium isotope ratios, and dead carbon fractions (DCFs), indicates that a rise in the local groundwater during periods of enhanced groundwater recharge is the cause of the cave flooding events that trigger pendulite growth. Uranium–thorium dating of a pendulite retrieved from Mairs Cave has revealed two multi-millennial growth phases (68.5–65.4 and 51.2–42.3 ka) and two short bursts of growth (18.9 and 16.4 ka) during the Last Glacial Period (LGP). The absence of subsequent pendulite growth suggests that strong water deficits under warm Holocene interglacial conditions give rise to episodic, rather than persistent, cave flooding.

Interesting paper out recently in ClimPast - subaquous speleothems record groundwater recharge in Mairs Cave, South Australia.

The deadline for the S-4 (@s42025.bsky.social) #Speleothem summer school to be held in October in Morocco is coming up in ~10 days—see below for details👇🏼

Hi #speleothem folks, April is the month for third episode of ICCP speleothem lecture series. Dr. @annabelwolf.bsky.social will share her insight about Southeast Asian monsoon in past, present and future using water isotopes. E-see you on 21st April, 09:00 am KST

Recurrent humid phases in Arabia over the past 8 million years - Nature A climatic record from desert speleothems shows that the central Arabian interior experienced recurrent humid intervals over the past 8 million years, which likely facilitated mammalian dispersals between Africa and Eurasia.

Always a good day when friends have a good day! Out today in NATURE (!) from Monika Markowska - 8 million year record of recurrent humid phases in Arabia.

So much stuff going on! We’re getting ready to finish uploading a database of European ostracodes, building tools to work with #speleothem researchers around the world, and getting ready to meet a fantastic group of #aeDNA folks for one of our next grants. Neotoma really is one big packrat midden!

Yesterday was so productive. Adding more taxa to @neotomadb.bsky.social and working in more stable links to the @gbif.org taxonomic backbone, and getting new data structures up to support the #speleothem community. Today, it’s like a chore to even get my tea brewed. But we move forward…

Cave and Karst Science Issue 51(3). Now available online and on paper.

🧪 in the latest OA issue of the #BCRA Cave and Karst Science we report on newly identified #speleothem growth periods during #MIS4 & #MIS3 in #Assynt, northern #Scotland 😜
More speleothems- less ice - more info on glacial climate. Kudos to a lovely team to work with! 👇

For #speleothem experts: We use trace elements (Mg/Ca) to derive semi-quantitative cool season precipitation amount and combine that with stable isotopes 💪. The result shows: dynamic - (not thermodynamic) processes determine precipitation variability.

Picture in a cave, showing some older stalactites that are not well formed, possibly due to human action. There are some bright spots at the tips of the stalactites where water is dripping off.

Today's travel in Kikaijima took me to Ufuyaguchi Limestone Cave. Before World War II, this cave was full of speleothems, but they were removed to make it a bunker. New speleothems are starting to form, though. ⚒️ #Japan #speleothem #cave
