Dissolved inorganic carbon supports robust anabolism and methanogenesis in actively serpentinizing rocks Serpentinites, hydrated ultramafic rocks that produce [hyper]alkaline, reducing, H2-rich groundwaters, host subsurface microbial ecosystems. Though in the presence of enormous reducing power, life in ...

Excited to share our pre-print examining microbial activity and carbon utilization in the serpentinizing subsurface! Tl;dr: Serpentinite-hosted microbes are notably active, thriving on DIC despite alkalinity. Implications for #astrobiology, #carboncapture, and #GeoH2!

Bluesky is now open. Science Twitter, here’s how to use it! The once-great science twitter is, depending on who you talk to, either dying or dead. Once a vibrant place for many discussions related to my fields of marine biology, ocean conservation, and publ…

Friends, I wrote up a quick guide to getting started on Bluesky for folks who are used to old Science Twitter.

Please share it with your folks who are joining. And please let me know if I missed anything or got anything wrong. 🧪

HiPOD: Detecting Olivine near Noachis Terra

Olivine turns into other minerals in the presence of water, so scientists are interested in looking for those minerals as well.
