Honored and excited to receive an #ERCStG! Looking forward to pursuing a research idea I have been working towards for a long time: using speleothems to reconstruct past tropical-cyclone activity and investigate its links to climate variability and extreme rainfall. @erc.europa.eu

We have a new preprint in #Geochronology discussions! Have a read - especially if you’re interested in speleothems and how to date them in presence of high and variable initial Th contamination… find our new chronology from a Maya archeological site on the Yucatán peninsula here… ⬇️⬇️⬇️

Challenges of initial Thorium and Approaches to Robust Speleothem Age Models: A case study from the Yucatán peninsula, Mexico
Abstract. Speleothems, such as stalagmites and flowstones, are invaluable archives of past environmental and climatic conditions due to their layered growth and suitability for precise 230Th/U dating....

With the threats being levied against NOAA, I felt it was time to download all the sediment core and paleoceanography data being stored on NOAA's NCEI, just in case. I have uploaded the script to Github, just in case anyone wants to do the same! 🧪 ⚒️ 🦣 🌊 github.com/evangowan/EJ...

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.
