We lost an absolute legend recently - Kristina Gjerde was fearless defender of the ocean and all of its marvels 💪 🌊 iucn.org/news/202512/...

Well this seems important: perhaps Titan doesn't have a subsurface ocean after all... www.nature.com/articles/s41...

Good morning Nee Orleans 👋 Excited to #AGU!

The UN's "Biodiversity Beyond National Jurisdiction" treaty (aka the "High Seas Treaty") is about to take effect - great! But what does it mean for scientists working in international waters? What will we need to do to be compliant and, ideally, helpful? We wrote a paper to answer these questions 👇

Biological surveys reveal unexpectedly high faunal diversity at Nankai Trough methane seeps esajournals.onlinelibrary.wiley.com/doi/full/10....

Major geological pilgrimage yesterday! 😍

Despite their prominence in the deep sea, ammonia oxidizing microbes don't play a huge role in carbon cycling. They're around, just not very active, starved for nitrogen... 🧪🌊 www.nature.com/articles/s41...

Between this and similar news at the University of Nebraska (where the Dept of Earth & Atm Sci has been earmarked for elimination), geology departments seem to be on the front lines of academia budget cuts. This would be a tragic loss for young scientists and citizens alike 🧪

western science 🤝 traditional knowledge What exactly is it about Marshall Islands sailors that allows them to navigate across vast oceanic distances without fancy tools? Excited to see what comes of this study! www.nytimes.com/2025/11/18/s...

Oranges left for two weeks in tupperware: a completely intentional microbiological study 😂😜

😮😮😮

Hey members, don't forget: Issue 25 of Deep-Sea Life is online! #DeepSeaLife is a biannual newsletter run by @deepstewardship.bsky.social & #DSBS to showcase the #DeepSea scientific community. Thanks to #DOSI & all contributors! Find it here: www.dosi-project.org/deep-sea-life/. Happy reading!

🌊😍 Even when the heat vanishes from hydrothermal vents, energy abounds in the chemicals and minerals that remain…

The age-old question: is it worse to instinctively reach for your house key when entering your office, or your office key when entering your home? Asking for a friend... 😂

This looks like a good one!

What makes a hobby? Can we really just do something for its own sake anymore? Interesting stuff from @newyorker.com: "A committed hobbyist...must strive to be proficient but not professional, creative but not productive, ambitious without being anxious..." www.newyorker.com/culture/open...

Over the last few years, I had the pleasure of serving on the Mars Sample Return Measurement Definition Team. Our driving question was straightforward enough: what do we do with precious samples that will hopefully be returned from Mars in the coming years?

An excellent guide to carbonate burial dynamics in ocean sediments - the most prolific route of carbon removal from the atmosphere... www.frontiersin.org/journals/ear...

Coming soon(ish)! 🎉🌊

Annoyed by low signal for your FISH experiment that hybridizes to a brief snippet of ribosomal RNA sequence? Why not make your own probes that target, you know, the *full genome*? 🤯 Really interesting new approach called GenomeFISH! academic.oup.com/ismej/articl... @isme-microbes.bsky.social

Hi UK friends! If you're looking for a fun deep-sea read in the spring, today's your chance to grab The Dark Frontier on sale! 🦑 www.waterstones.com/book/the-dar...

Guess what y'all - the great @okaysteve.bsky.social has a book coming out November 4th: "How to Change a Memory"! Steve is a genius, and this book is no doubt going to be an awesome read. Pre-order it now if you know what's good for you! press.princeton.edu/books/hardco...

A lovely recap of our Chilean Seeps & Canyons cruise, from @schmidtocean.bsky.social's annual report. Excited to start sharing some of our findings in the months ahead! 2024annualreport.schmidtocean.org/canyons-vent...

Yay methanotrophs! My favorite type of microbe... 🥰 www.nytimes.com/2025/10/06/c...

A huge field of hydrothermal vents - driven by serpentinization and formed by a massive hydrogen explosion - recently discovered in the western Pacific! www.science.org/doi/full/10....

The BBNJ "High Seas" Treaty has been ratified by 60 countries and is now officially in effect! What a journey it's been... 🎉 www.nytimes.com/2025/09/19/c...

Loving this set of vignettes about microbes' role in climate dynamics 👏 www.quantamagazine.org/microbes-als...

Space weathering effects in Bennu asteroid sample! This paper reads like a bit like a geomorphology textbook on the microscale - really cool to see how minuscule observations can point us to process. www.nature.com/articles/s41...

A microbial community's composition can help reveal the mineralogy of its surroundings 😮 www.nature.com/articles/s43...

Never has an article headline spoken more directly to me 😂 www.bostonglobe.com/2025/08/23/m...

Score another one for the microbes! Somehow not surprising, but astonishing at the same time - the tree microbiome 👏 www.nature.com/articles/s41...

Latest season of VolcaKnowledge has dropped! Stop by to learn about the many (and surprising) ways that volcanoes affect us, no matter where you live. 🌋 www.youtube.com/channel/UCD9...

Oh check it out, @microbesheik.bsky.social found some cool microbes in "mysterious goo" from a ship's rudder shaft...and I got to talk about it 😂 www.cnn.com/2025/08/01/s...

Check out "the deepest and the most extensive chemosynthesis-based communities known to exist on Earth" - methane seeps along Russia's NE coast, down to a depth of 9500 meters! 😮 It's amazing that such incredible ecosystems remain to be found in the deep sea... www.nature.com/articles/s41...

Eeeek, this would be bad!

Check out this beautiful doc from @fieseler.bsky.social on nodules & "dark oxygen" - honored to be part of it! Our (and others') research on dark oxygen remains bewildering, exciting...and critically important as we try to understand how the deep sea really works. www.youtube.com/watch?v=1jcm...

For marine invertebrates, the deep sea - unlike shallower coastal waters - is all connected... www.nature.com/articles/s41...

The year’s crowning achievement! 🙌😂

Oooh so cool! Sea spiders that farm methane-eating microbes on their exoskeletons 😮 Methane seeps never cease to amaze... www.pnas.org/doi/full/10....

"Why we should protect the high seas from all extraction, forever" This is an uphill battle (to say the least), but a compelling case! Mostly the argument is, we just don't need stuff from the high seas, so why go to the trouble? 🤷 www.nature.com/articles/d41...

Could this be a way to keep synthetic microbes released into the environment in check? Forcing a dependence on a non-standard amino acid produced by a partner microbe... www.nature.com/articles/s41...

Made a science pilgrimage to St. Anthony Falls Lab the other day! It’s right next to a dammed part of the Mississippi River, and uses the water flow to run large-scale hydrology and geomorphology experiments. Part of the river can essentially be diverted to run *through* the building!

Lovely visit to @uconn.bsky.social last week! Learned a lot about low-cost nitrate and ozone sensors 😮👏

Recently upgraded Alvin can now dive to 6500m. Read our new article about its capabilities, latest #deepsea science discoveries, & new milestones on its #science verification expedition 🌊🛠🧪. Thx to the entire whoi.edu Alvin team & funding from #NSF-funded #USONR @noaa.gov @urigso.bsky.social

New paper alert! 🚨 (Well, a preprint for now :) Introducing "Dual-BONCAT" - a new approach to distinguish two different metabolically active subpopulations within a single microbiome experiment. biorxiv.org/content/10.1... A little more info in the thread below 👇

Hello bluesky 👋 For all you oceany people out there --> dive alert in the SE Pacific, just off the coast of Chile! We're exploring some previously unvisited submarine canyons to study their geological foundations and catalog their biodiversity. Follow along here! www.youtube.com/watch?v=BZ1i...
