#diagenesis — Public Fediverse posts

#WeekendReading: Akhtar et al. show a multi-element/isotopes approach to explore the differences in early #diagenesis of #carbonates with marine and meteoric fluids, as well as along the gradient.

#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.

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 (https://meetingorganizer.copernicus.org/EGU24/EGU24-16400.html) and on Zenodo https://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

#WeekendReading: Monedero-Contreras et al. discuss why they think #sapropels initiated and terminated abruptly, how #diagenesis complicated detecting the termination and what it might mean for other oxygen depletion events.

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?

Scientist's life is: hardly being able to sleep from excitement. This week we kicked off not one, but TWO new projects with two new team members. The second one will be experimental #diagenesis in #foraminifera, which are widely used for #climate reconstructions. They record the #isotope composition of the seawater in which they lived, but that composition may be altered after their death - we will try to reproduce this experimentally in the lab as part of a nessc.nl project. I started a #palaeontology BSc course 👩🏼‍🏫 by incorporating analytical methods and teaching students documentation of their analyses by using #RMarkdown. It is an attempt to change the perception of #palaeontology from descriptive and exploratory to a more hypothetico-deductive and quantitative field. And I finished at the Uni of Leicester 🇬🇧 with the big honour of examining a PhD candidate who epitomized this approach by establishing a quantitative proxy for the trophic level of #conodonts and possibly any #invertebrates with dental tools. And that's just the highlights. It's a big privilege to be a scientist.
