Oceanic mesoscale eddies are often thought to have coherent structures that trap water in their cores.🌊 However, a new study shows that smaller-scale motions, known as submesoscale stirring, can disrupt this coherence. 🔗 doi.org/10.1029/2025... #AGUPubs #Oceans #Oceanography @agu.org

Nobody *likes* pollution…but sometimes it has its uses as a research tool.

You know how antacids can take a while to start working? New research finds that calcium carbonate minerals—the ocean’s version of antacids—might work on faster timescales than scientists realized.🧪🌊 Work out of @universityofotago.bsky.social in @aguadvances.bsky.social. eos.org/research-spo...

2️⃣ A new study led by @icecoldwill.bsky.social in @jgroceans.bsky.social looks at the ocean's role in limiting winter sea-ice growth. A metric called “Stability at Freezing Temperature” estimates how much heat the ocean must lose to the atmosphere for ice to form. ▶️ doi.org/10.1029/2025...

Oil spills in the ocean typically don’t reach beyond a few hundred miles. But when oil meets plastic debris, it can travel much, much farther. Read more, or listen, here:

Hats off to the New Zealand team behind this research in @jgroceans.bsky.social. Drilling through ice shelves is no easy feat. ▶️ aapp.shorthandstories.com/how-to-drill... @aucklanduni.bsky.social @universityofotago.bsky.social

Happy #CTDAppreciationDay to all who celebrate (and we do)! Here's how researchers are studying Arctic fjords with crowdsourced science, sailboats, and CTDs. eos.org/articles/stu...

A smidgeon of good news for the ocean.

Oh, the weather underwater is frightful! New research by scientists at @ucsantabarbara.bsky.social + colleagues finds that marine snow’s movements are driven by surface storms and zooplankton. #AGUPubs

Downscaling is a common technique used in ocean prediction models to take large-scale information and refine it for local applications. Eidt et al., test the performance of a downscaling technique in the Northern Adriatic Sea 🌊 agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Remotely operated kayaks let researchers from @marine.rutgers.edu + colleagues gather rare data from the base of a melting glacier. The results, in @jgroceans.bsky.social, offered unexpected insights about how seawater and freshwater mix near marine-terminating glaciers. eos.org/research-spo...

Global ocean models tend to oversimplify the way river chemistry affects coastal seawater. New research takes a step toward fixing that.

U.S. withdrawal from international climate bodies sidelines scientists when climate impacts are accelerating. AGU remains engaged at UNFCCC COP, supports U.S. scientists in the next #IPCC assessment, & urges Congress to protect science funding. Science belongs at the table. More: buff.ly/sYY3rVB

Since 2015, the amount of Sargassum in the northern Sargasso Sea has decreased by more than 90%. eos.org/articles/the...

Key findings: 🔥 Summer: Most heat flows toward glaciers, concentrated in the upper 150 m thanks to subglacial discharge. 🌀 Winter: Circulation is surprisingly strong but more 3D than in summer. ➡️ Two distinct winter inflow events: one cold & deep, one relatively warm!

Antarctica in the winter? Yeah, it really is that cold 🥶❄️🧪 A postcard from the bottom of the world: eos.org/postcards/an...

New research led by @andreasschmittner.bsky.social @osuceoas.bsky.social simulates an AMOC collapse to learn how it could affect ocean carbon storage, isotopic signatures, and carbon cycling. #AGUPubs 🧪🌊 eos.org/research-spo...
