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.

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.

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.

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

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.

Recently @pbs.org visited our Vault, aka the Gulf Coast Repository at @tamu.bsky.social where a core drilled at ground zero of the dinosaur impact is stored. The GCR also houses records of the planet’s climate, plate tectonics, volcanic eruptions, and so so much more. youtu.be/IYb3duBY_IE?...
