American Geophysical Union (AGU)

In honor of World Ocean Day, we are excited to share a recently published paper from AGU Advances. 🌊

In van de Velde et al. (2026), the authors identify a previously unaccounted for calcium carbonate buffer feedback cycle exists off the coast of . These calcium carbonate buffer responses help keep atmospheric carbon dioxide levels and ocean acidity in check. What was previously thought to only occur in the deep ocean also occurs in shallow waters, and quicker than the deep ocean counterparts.

Our Ocean’s “Natural Antacids” Act Faster Than We Thought - Eos New evidence from New Zealand suggests that calcium carbonate dissolution occurs not just over millennial timescales, but over annual and decadal ones too.

Along mid-ocean ridges, hydrothermal vents circulate fluids enriched with elements into the ocean environment, changing the chemical composition of seawater. Novel methods and techniques are advancing understanding of hydrothermal systems and their impact on the Earth system. 🌊

World Ocean Day

In support of the UN Ocean Decade, a new special collection welcomes articles that showcase the broad range of solutions-focused research and capacity-sharing efforts that meet the Ocean Decade's vision: "the science we need for the ocean we want."🌊

On World Ocean Day 2026, we highlight the conservation efforts that aim to restore ocean habitats. Climate stability depends on healthy oceans, and scientists are working hard each day to ensure that the oceans are protected for future generations.🐟

AGU’s JGR: Oceans showcases this work. In a recent article, Geldard et al. find that coral reef restoration efforts can lead to a reduction in wave height and therefore can reduce coastal flooding and erosion.🌊

"We believe that open development practices can lead to both efficient and maximally impactful outcomes."

In AGU's Perspectives, researchers argue that a model called co-creation is a powerful strategy for accelerating scientific progress through open approaches.🔬

Some thunderstorms grow so tall that they reach into the stratosphere, transporting water v***r and other chemicals upward where they can influence atmospheric composition and climate. But what conditions cause this to happen?⛈️

Using aircraft observations over the United States, scientists investigate which storm and environmental conditions create the greatest impacts.
