  1. RE: social.uibk.ac.at/@uniinnsbruc

    The #ancient #Roman #city of #Pompeii at the Gulf of #Naples offers remarkably #wellpreserved #insights into #dailylife before it was buried by Mount #Vesuvius in 79 AD. G. Sürmelihindi et al. (2026) investigated the #carbonate #incrustations in the #baths, the #aqueduct, and in #wells, with the latter being replaced by the penultimate as #technical #improvement. The periodicity of #δ13C variations from wells and republican #pools indicated poor #hygienicconditions.

  6. Hygienic conditions in Pompeii’s early baths were poor: Limescale deposits in wells, pipes, and bathing facilities provide information about Pompeii's ancient water supply 👉 press.uni-mainz.de/hygienic-co

  7. 🚨 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.

  8. 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 egusphere.copernicus.org/prepr or try CarboKitten.jl at mindthegap-erc.github.io/Carbo

  10. Rocks breaking in tension, compression, and shear; an interesting teaching talk yesterday by Dr. Drew Lubiniecki. Below is a fascinating figure showing the loss of porosity in deformation bands (DB) in a sheared carbonate. The original porosity is shown in blue.

  11. Just a gentle reminder that through geological time, shifts in #carbonate producers mean that the geometry of carbonate platforms (as well as #reef shape) changed.
    Please try to keep that in mind when drawing your models. I'm trying to stay mad, but I'm actually just growing disappointed.

  12. Somehow, with everything going on, I forgot to acknowledge that the term started (and now a few weeks in). As taxing as it is, it's nice to be back in the classroom. Being able to talk about the #marine #carbon system and #carbonate rocks to #students is a nice change of pace.

  13. Thermal-induced #crystallographic transformation in shells of #mussels reveal that crystallographic features in the #carbonate are more resistant to #diagenetic alteration than stable #isotope ratios.

  14. #WeekendReading: Cala et al. on the dissolution kinetics of #carbonate minerals in the oceanic water column. Showing that the dissolution rate is proportional to the saturation state, seems trivial, but it really isn't.
    Something like this was much needed for a while now.

  15. #NewPaper out in the world!
    What destroys a #carbonate (#mesophotic) platform? It turns out that erosion, destabilization, and lower slope dismantling all work independently of each other.

  18. #WeekendReading: Catching up on Wei and Zhang's thoughts on shallow-water #carbonate early #diagenesis. I think I'd like to play again at some point with this idea of diagenesis based correlation.

  19. Cold seeps are apparently rather prevalent on the US Atlantic margin. To me that supports that near-seafloor #authigenic #carbonate formation (which happens there) is likely much more prevalent than previously considered.

  20. We've been working on a massive riddle tying together #self-organization, #carbonate #diagenesis, reactive transport, #paleoclimate and #Milankovich cycles, and very stiff PDE systems.

    If you've missed the poster at #egu24, you can still find it attached to the abstract in the conference program (meetingorganizer.copernicus.or) and on Zenodo zenodo.org/records/10943274 If you're into numerical methods, tricky PDEs or other aspects of #modeling, please see if you have any advice to us 😄 #solvers #PDE

  21. In case you missed it - my talk from last week at the at #DGGV Sedimentology Lunch on how #carbonate factories in the #Mediterranean responded to it's restriction over the #Miocene is now available on YouTube.

  22. #Ediacaran #fossils reveal origins of #biomineralization that led to expansion of life on Earth
    phys.org/news/2023-09-ediacara

    Constraining the onset and environmental setting of #metazoan biomineralization sciencedirect.com/science/arti

    "#Cloudina originated in a low #oxygen environment with periods of notably higher #oxygenation... it was not a case of sustained oxygenation that resulted in the appearance of #skeletonization... high #carbonate concentrations in the ocean were necessary"

  23. can form when cool groundwater warms as it rises to the surface. Calcium carbonate exhibits inverse solubility -it's less soluble in warmer water. As a result deposits can form -like those at Mono Lake. A nice write up of groundwater carbonate deposits at:

  24. Developing Tailored Data Combination Strategies to Optimize the #SuperCam Classification of Carbonate Phases on Mars: agupubs.onlinelibrary.wiley.co -> Optimizing #Carbonate Classification on #Mars: eos.org/research-spotlights/op - combining data from several of #Perseverance rover’s spectroscopic sensors offers a more accurate means to classify carbonate #minerals that may hold hints of ancient life.

  25. New work by @bach_lennart

    The experiments show that anthropogenic #alkalinity can strongly reduce the generation of natural alkalinity, thereby reducing additionality. This is because the #anthropogenic alkalinity increases the calcium carbonate saturation state, which reduces the dissolution of calcium #carbonate from sand, a natural alkalinity source.

  26. I think that at this point we established the #Bahamas is an anomaly - can we stop use it as a benchmark to explain #carbonate depositional environments and #diagenesis?

  27. It's back to the #RockyIntertidal of #Washington's #SanJuanIslands this #MarineLifeMonday, this time to visit an odd #seaweed group. Coralline red #algae are distant relatives of plants, but they're named because they look like some types of #coral. In fact, this similarity is more than skin-deep. Just as coral animals often encase themselves in calcium #carbonate shells, these algae line their cell walls with the same #mineral, making them much more rigid than other #seaweeds.
