[For almost 300 years – from 1709 to 2004 – Penicuik and district was producing high-quality paper which went out all over the world; Walter Scott’s Waverley novels and Robert Louis Stevenson’s notebooks were printed on Penicuik paper, and Turner painted on it too.]

🚨 talk announcement! 🚨
How does the geological record form?
We can observe modern depositional environments using advanced remote sensing and direct sampling.
We can observe geological strata through seismics, drillcores, and direct sampling.What happens in between?
Xianyi Liu in my team is trying to find out, using the oldest known aerial photographs of the #Bahamas, and comparing them with today's facies distribution. It's a journey through #carbonate #sedimentology, #GIS, modelling and #MachineLearning. If you'd like a sneak peek, join his talk coming Tuesday at 17:00 CET at PaleoPERCS.

Some more #work stuff.
Getting an European Research Council (ERC) grant had this terrible outcome that I thought: now we can do in-depth, thoughtful research without cutting corners and ducktape solutions. Understanding #evolution in the #fossil record required a reproducible model representation of that record and we weren't satisfied with any of the existing models. Computer models made by (Earth) scientists are rarely very good, because we are not necessarily trained to make them, but to model events happening over hundreds of thousands of years, we crucially rely on their quality.
So we decided to develop one. Thanks to its main developer Johan Hidding @eScienceCenter and the collaboration with Peter Burgess, Xianyi Liu and @Niklas_Hohmann we have a fast, sustainable, #OpenSource package in #julialang for modeling #carbonate platforms.
The preprint is out for public review: please leave us a comment at https://egusphere.copernicus.org/preprints/2025/egusphere-2025-4561/ or try CarboKitten.jl at https://mindthegap-erc.github.io/CarboKitten.jl/
