New paper from my colleague and friend Julio Cauhy, reconstructing extreme rainfall events in Southern Brazil over the past 7.5 ka. Julio and colleagues combined cave monitoring with painstaking petrography and careful U-Th dating to analyse detrital flood layers in speleothems from Malfazido cave. They found that extreme rainfall events are influenced by Antarctic-tropical teleconnections, and that El Nino events had an important contribution in the last millennium. It's a fantastic piece of work!

🔦 Feldforschung in Alaska: Der #Geologe Paul Wilcox entdeckte dort in einer schwer zugänglichen Höhle rund 20.000 Jahre alte Ablagerungen. Eine Analyse dieser Proben erlaubte Rückschlüsse über das Ende der letzten #Eiszeit und darüber, wie das Abschmelzen der riesigen Gletscher damals vor sich ging.

Another excellent edition of Quaternary Australasia is out! I always enjoy the post-conference student reports, especially when the students seem to have really gotten into the 'AQUA vibe'!

Dating Speleothems and Speleothem Growth
On Sunday I was invited to give a Science Forum webinar to the Australasian Cave and Karst Management Association. The topic was 'Dating Speleothems and Speleothem Growth'. The recording is now up on the ACKMA website. Although the talk was aimed as cave managers and guides, I hope it will be useful for anyone interested in caves and how they can be dated, as well as educators in the field of landscape evolution, Quaternary Science, stalagmite paleoclimate and caves and karst geomorphology.

If you are interested in paleoclimate, Quaternary environments, cave science or speleothem science, this pre-print might be of interest
The global speleothem isotope database SISAL has been updated to version 3. The oxygen and carbon isotope data included in previous versions of the database have been substantially expanded.
SISALv3, contains speleothem data from 364 sites from across the globe, including 94 Mg/Ca, 83 Sr/Ca, 51 Ba/Ca, 25 U/Ca, 29 P/Ca and 14 Sr-isotope records. The database also has increased spatiotemporal coverage for stable oxygen (831) and carbon (588) isotope records compared to SISALv2.
Want to read more? The preprint is:
SISALv3: A global speleothem stable isotope and trace element database, led by Nikita Kaushal and co-authors, and the preprint is now accessible and open for interactive public discussion until 18 Oct 2023 at: https://essd.copernicus.org/preprints/essd-2023-364/
