It now costs more to cause climate change than to prevent it

On Svalbard Exp403 scientists just had the rare chance to observe the sources & processes of ice-rafted debris found in our drill cores. IRD = rocks broken off by glaciers on land, rafted out at sea on icebergs, & dropped on the seafloor. It's an important indicator of past climate dynamics.

Our very first GCR user spotlight features Anuska Pudasaini, a PhD Candidate at the Department of Earth and Atmospheric Sciences at the University of Houston. Anuska analyzed grain sizes of Antarctic sediments using our Bettersizer S3 Plus Particle Size and Shape Analyzer. #GCR #NSFfunded

Fire update: thanks to heroic efforts by contractors & USF CMS ops staff, my group got most of our samples. Yesterday books emerged. Waiting for space allocations for prep labs & offices. Instruments & buildings will take longer; advocating for mobile labs in short to mid term. Funding still needed.

It's not just the sun's rays; the wind is doing some big work, too. 💨Did you know, Texas LED the nation for wind generation in 2025 at 129,458 GWh? ❗That outpaced the #2 producing state, Iowa, by ~86k GWh ☀️Texas was #2 for solar generation at 64,073 GWh 📊 www.climatecentral.org/climate-matt...

In April, researchers from across Europe and beyond met in Granada for the IODP Expedition 401 post-cruise meeting. Scientists shared post-cruise research results, providing new insights on how the Atlantic and Mediterranean exchanged water during the Messinian Salinity Crisis. (cont. in thread)

As many know, there was a massive fire at USF CMS. The building held offices, labs, equipment, etc and is a total loss. We are most concerned about the finanpcial losses of our students. Please consider donating to the official go fund me supporting our graduate students.

Fire is out at the USF St Petersburg College of Marine Science - happily nobody was injured, but it doesn’t look good for the building

It was a great science meeting!

New report! Advancing Future Ocean Drilling in the United States (FOCUS) was a community effort to identify priorities for US SciOD in the first phase of post-IODP drilling, with an emphasis on needs for new expeditions. Read the report at usoceandiscovery.org/focus. Thanks to all who participated!

This Saturday, SODCO will be participating in the American Museum of Natural History EarthFest. If you're in NYC, check it out! We'll be in the Hall of Ocean Life with a giant inflatable model of the JOIDES Resolution, ready to chat about SciOD! EarthFest details: www.amnh.org/calendar/earthfest

As a fire scientist, I am devastated for my many good friends and colleagues who will be affected by the mass closure of so many research stations and offices. Many will leave the agency. USFS has pioneered so much foundational fire science. The consequences of this will be catastrophic.

Welcome to the GCR! We serve the global scientific community by preserving scientific ocean drilling sub-seafloor samples, facilitating cutting-edge research through access to geologic samples and world class laboratory facilities, and training the next generation of geoscientists. #GCR #NSFfunded

Check out our International Ocean Discovery Program Data Report from Site U1521 in the Ross Sea, published today! Thanks to my coauthors including A. Shevenell, D. Kulhanek, C. Prunella, and the Exp 374 Scientists for their efforts towards this 🎉 🇦🇶 🚢 publications.iodp.org/proceedings/...

Love how this image captures the mission's "For All Humanity" motto. There are no borders in space! But to get oriented a bit better, here is a version I annotated. Still can't wrap my head around how amazing this picture, the Artemis crew took, is.

A reminder to the news media: “conflicting accounts” is what you say BEFORE the incontrovertible video evidence appears. After that, your job is to ask why one side is lying, not to repeat the lie and pretend no one knows the truth.

New Year, New Us. Looks like our new Scientific Ocean Drilling branding is up. You can still find us at our usual spot on @tamu.bsky.social’s West Campus.

🚨POSTDOC JOB ALERT🚨 We have an exciting opportunity for a 2 year postdoc on remote sensing of icebergs and marine terminating glaciers. See the link below for more info! Please spread widely, and feel free to email me with any Q's :) tinyurl.com/2jjcmea9

Speaking of the GCR, if you want to spend a week there to learn about scientific ocean drilling, analytical techniques, work with legacy cores, etc. apply here by Feb 15th, 2026 gcr.tamu.edu/outreach/upc...

A new field of “soilsmology” :)

We invite applications for two graduate students to investigate Antarctic ice sheet instability during past warm interglacials using marine sediments. Please share with students who may be interested to join our group at USF! Contact me for details; deadline 15 Dec. www.usf.edu/marine-scien...

Not under her own power anymore, the vessel that revealed more about our planet than most others, the legendary JOIDES Resolution is being towed to a pre-cleaning yard in Lyngdal, Norway. First pic I've seen of her since stepping off in August 24. Still looking great 🫡💔 www.fvn.no/magasin/i/8q...

New publication!! Featuring some of the most gorgeous rocks I’ve ever cored, tremendous work by an international, interdisciplinary team, and interesting implications for marine CDR. Article: www.nature.com/articles/s41... News & views: www.nature.com/articles/s41...

New data alert 🚨📣: Updated Coastline and Rock Outcrop of Antarctica released as part of the @scar-antarctic.bsky.social Antarctic Digital Database. With big improvements to date formats, coastline positions and more accurate rock outcrop! 📍View and download via the map viewer add.scar.org.

The initial SODCO website is now online and will evolve over time. Keep an eye open for Scientific Ocean Drilling events (looking at you @agu.org Annual Meeting) and announcements about proposals, workshops, expeditions, internships, etc… www.sodco.org

I heard it’s headed to Turkey to be scrapped. RIP

🌊In a new study co-led by USF professor @oceanandclimate.bsky.social Patrick Rafter, researchers used forams from the Pliocene to show that warming in the tropical Pacific may not trigger the severe decline in nutrients predicted by earlier models. www.usf.edu/marine-scien...

Texas is nearing 100 gigawatts of emission-free power (solar, wind, storage, nuclear). EIA reported yesterday that the US will install 50 gigawatts of solar + storage in 2025, 40% of it in Texas. That & much more in today's Grid Roundup. Link in reply.

😓 These are the folks who provide satellite imagery, maps, and geospatial support to American scientists that operate in polar regions where most satellites don’t reach. FOR DECADES they have done this, supporting critical work. They have helped me many times. This is terrible. #WithoutNSF

Studying the role ocean circulation played in shaping past climate and glacial dynamics, I’m absolutely captivated by this new NASA simulation. Check out the full video here: svs.gsfc.nasa.gov/vis/a010000/...

Sediment coring: examining a rich and ancient 'layer cake' of #Antarctic climate change New records from the sea floor near the Denman Glacier and Shackleton Ice Shelf offer crucial insights dating back thousands of years, writes Dr Taryn Noble ⬇️ #DMV @utas.edu.au antarctic.org.au/sediment-cor...

Offshore to the west of the Denman Glacier, the Kasten core sediment tubes keep on coming - and this one, retrieved from the seafloor this week, is a keeper #DMV Taryn Noble (@utas.edu.au) leads the research team to examine its many interesting layers ⬇️ 📷: Katharina Hochmuth, Delphine Lannuzel

The first time Sidney Hemming (from @lamontearth.bsky.social) sailed on JOIDES Resolution was in the role of a co-chief scientist. But this is just one part of Sidney’s "big adventure" for IODP Expedition 361. Take a listen at #TalesFromTheDeep in the StoryCorps Archive. 🧪🌊⚒️

These rocks were retrieved from the first dredge, deployed to a water depth of 2700 metres on the steep eastern slope of the Eastern Bruce Rise. Further dredges are planned, including to features that may be extinct underwater volcanoes. @utas.edu.au 📷: Katharina Hochmuth / Delphine Lannuzel

Please note that our labs now also have windows ☀️ It's sad that the JR got retired, but with all the ship's lab equipment here, the GCR has quickly been transformed to a cutting edge core research facility!
