Jannik Martens et al. (2026) Geochimica et Cosmochimica Acta present a valuable #tetraether #lipid dataset—isoGDGTs, #brGDGTs, and OH-isoGDGTs—to improve our understanding of #TeamArchaea #GDGTs distributions in central #ArcticOcean sediments—surface #sediments and #sediment cores:

To what extent #anaerobic #methanotrophic (ANME) #archaeal inputs may bias #sea surface #temperatures reconstructed with #TeamArchaea hydroxylated #isoprenoid #tetraether #lipids?
Pierrick Fenies et al. (2026) #OrganicGeochemistry tackled this question in their new #scientific #publication:

This year, I am part of the @EuroGeosciences #EGU26 goers and presenters!
Indeed, I will talk about my latest piece of work this afternoon:
https://doi.org/10.5194/egusphere-egu26-19334
Featuring hydroxylated #archaeal isoprenoid #tetraether #lipids!

I am so happy to co-author this #preprint #review on #archaeal #tetraether #lipids, aka #GDGTs, as #marine paleoenvironmental indicators led by Felix Elling and Gordon Inglis!
The #consensus presented in this preprint review was written by 40 experts on GDGTs, including both lead authors and myself.
The Earth and Space Science Open Archive preprint is available there:

Let's give a try to the new #QuotePost functionality, so that I can remind the names of the lead authors of my new co-authored #review paper published in the @EuroGeosciences #journal #Biogeosciences, as well as which team and research center I represent in this #synthesis!

As we* hoped, my co-authored #marine GDGT « cookbook » #review #paper (https://doi.org/10.5194/egusphere-2025-1467) was accepted for publication in the @EuroGeosciences #journal #Biogeosciences after peer-review and (minor) revision! 🥳 🍾

This new #scientific #publication is in favor of a (further) consideration of isoGDGT-0 and crenarchaeol in addition to isoGDGT-1 to isoGDGT-3 and crenarchaeol isomer for paleo-reconstructions.
