Hydrothermal hydrogen! 🫧 An ROV dive revealed high levels of molecular hydrogen in vent fluids ejected from a bubbly ridge in the Norwegian Sea. 🧪

A Mid-Ocean Ridge in the Norwegian Sea Pumps Out Hydrogen - Eos
Vent fluids collected from the Knipovich Ridge contain unexpectedly high concentrations of hydrogen, potentially produced by the degradation of organic matter.

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.🧪🌊

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.

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:

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.

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!
