🚨PhD position alert!🚨 We're hiring a PhD to investigate isotope compositions of sulfur-bearing organic molecules to try to develop potential bio-signatures. Funded by NCCR Genesis and joint between Johanna Marin-Carbonne @unil.bsky.social and myself! career5.successfactors.eu/career?caree...

New paper in JGR:Solid Earth! We use hot springs to answer a seemingly simple question: How deep does water derived from the surface penetrate into the Himalayas? Tl, dr: it depends + fault type and deep volatile degassing matter agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Circulation Depths of Meteoric Water in the Himalayas: Controls and Implications for Seismicity

Meteoric water circulation is more prevalent along active fault zones, but its maximum depth is controlled by the fault's deformation style Variations in topography, orographic precipitation, and...

🚨paper alert!🚨 Thrilled to share our work, led by @climategordon.bsky.social, on terrestrial OC burial during the PETM, which was likely much higher then previously thought. Implications for C-cycle responses to hothouse climates! @natgeosci.nature.com www.nature.com/articles/s41...

Enhanced marine burial of terrestrial organic carbon through the Palaeocene–Eocene Thermal Maximum - Nature Geoscience

The burial of terrestrially derived organic carbon in coastal marine sediments greatly increased during the Palaeocene–Eocene Thermal Maximum, probably helping to draw down a large portion of carbon r...

Rock weathering can counteract river CO2 emissions induced by permafrost thaw - Nature

Permafrost thaw on the Qinghai–Tibet Plateau increases rock-weathering rates while reducing river CO2 emissions, suggesting geological carbon fluxes may eventually outpace thaw-driven emissions.

I will be presenting tomorrow some of our ideas around the landscape and hydrological drivers of terrestrial microbial sulfate reduction and how it affects pyrite oxidation quantification. If you are at @egu.eu do come around! Thursday, 7 May Room: -2.43 15:35-15:45 CEST Session ERE 4.5

Glacier retreat is reshaping water chemistry worldwide. By showing that melting ice can deliver both vital micronutrients and potential contaminants, this study highlights new challenges for managing fragile mountain and polar ecosystems under climate change. 🌐🧪

🚨 Paper alert! 🚨 Happy to see this review out in @natureportfolio.nature.com Reviews Earth & Environ! We go through looming uncertainties related to wide-scale application of ERW. It will be a rocky path! @mschiedung.bsky.social @profbobhilton.bsky.social @eth-eaps.bsky.social @usyseth.bsky.social

Very excited to announce *TWO* fully-funded PhD positions starting this summer focusing on greenhouse gases in the peatlands of the Congo Basin! Both positions are joint between my group in @eth-eaps.bsky.social and that of @johansix.bsky.social @usyseth.bsky.social. Come join us!

🚨Paper alert!🚨 Very excited to finally see the thesis work of my ~first~ M.Sc. student published---and, to boot, it's in a special edition dedicated to the late, great Judy McKenzie! onlinelibrary.wiley.com/doi/10.1002/...

Hydrothermal dolomitisation of a deep‐water bioherm isolated in a non‐dolomitised intraplatform basin within the Norian Dolomia Principale (Southern Alps, northern Italy)

We propose that one of the largest known bioconstructions (the Monte Zenone bioherm) in the Southern Alps, northern Italy, and its growth on a tilted and drowned platform block of the Norian Dolomia ...

🚨 First #SEELab @eth-eaps.bsky.social PhD student-led paper is now officially online! We show that sedimentary conditions regulate formation rate and isotope composition of #pyrite, and that this process currently out-paces oxidation on land, leading to O2 accumulation www.nature.com/articles/s41...

Sedimentary conditions drive modern pyrite burial flux to exceed oxidation - Nature Geoscience

Modern pyrite burial in seafloor sediments exceeds pyrite oxidation on land, indicating that the sulfur cycle is out of balance, and acts to increase atmospheric oxygen levels, according to a diagenet...
