Geologist goes swimming: working on natural and enhanced silicate weathering @UUEarthSciences | interested in silica-carbon coupling, CDR and stable isotopes

[Sonja Geilert @steinlaus3]

Just out: Our Goldschmidt 2025 session on marine silicate alteration and impact on marine element cycles was just accepted!

If you have exciting new data on all (!) involved elements, consider submitting an abstract

So happy to announce that our #PRELIFE consortium was awarded🥳In one of 16 projects on the emergence of life, I will investigate the onset of silicate weathering and its coupling to ocean chemistry.

For the silica lovers: special emphasis on reverse weathering😉@UUEarthSciences

Btw:

Clays, clays, clays!

triggers directly

⛵️Boats! Boats! Boats!⛵️

Oh dear...😅🤪😵‍💫

Who knows what I'm talking about? Same effect?😏

[John Higgins @blueicehiggins]

Clays, clays, clays! Clays are complicated, but this paper does a nice job framing some of these complications using ISOTOPES (of silicon)! 👏! For all those interested in 'enhanced' 🪨🌧️ for CDR, these are the sorts of papers you should be👀! Ask yourself how your MRV is going to keep track of all the alkalinity passing through clays!

[Sonja Geilert @steinlaus3]

Thanks for the nice words! Highly appreciate it!

Using your comment to link 'my' CDR community to it. Can only emphasize: BEWARE of CLAYS and CO2 release during formation!

Finally it's out!🥳

Interested in detecting marine silicate alteration and element cycling using stable isotopes? Then you might like this one, where we show the diagenetic impacts on Si isotopes during authigenic clay maturation.

I can only join the applause!👏 Great fieldwork prep Steffi and Alice!

And what else can I say than:

'schist happens!'😝

[Sonja Geilert @steinlaus3]

Good to note as well:

Abstract deadline is already THIS FRIDAY (29.03.)!
😅🤪

So, put your data in a nice abstract and let's discuss it together @goldschmidt2024 !

Well done, Michi!👍
Our latest study highlights the challenges associated with the detection of mineral dissolution in the context of #CDR due to high natural background fluxes🌊

Great idea @climatejesper, thanks for making the effort👍👍👍 !

I really appreciate this compilation as it is really difficult to keep track in this quickly evolving #CDR field!

Hmm, quite tricky to find pics for mineral-water reactions in the water column and at the seafloor 😅

ClimateZone: t = -2days!

Unless humanity drastically reduces its greenhouse gas emissions, global warming is unstoppable, with
unpredictable consequences.

Our goal is to make climate change impacts perceivable in a creative-poetic way.

ClimateZone: t = - 3days!

We, the Institute of Climate Beauty, are getting ready!

In Kiel this and next weekend (16./17.+34./24.09.)? Then come and visit us at the Kielline, close to the aquarium.

Preserving climate beauty instead of managing
climate crises!
