Microscopic ocean algae produce a huge share of Earth’s oxygen—but they need iron to do it. New field research shows that ...

New research has revealed the importance of mineral forms of iron in regulating the cycling of this bio-essential nutrient in the ocean. The findings pave the way for new work on the relationship ...

I’ve spent hundreds of days at sea. In the high winds and towering waves of the Southern Ocean around Antarctica, I have worked alongside fellow ocean scientists to understand the impacts of climate ...

Iron-rich dust launched into the air by winds swirls around the Southern Ocean. Understanding how iron’s chemistry shifts during its journey from earth to air to sea will be important for developing ...

After a hiatus of more than 10 years, a new round of research into ocean iron fertilization is set to begin, with scientists saying the controversial geoengineering approach has the potential to ...

Marine chemist Ken Buesseler works on a "clap-trap" mooring during the Vertical Transport In the Global Ocean (VERTIGO) project in 2004. As its name implies, this study looks at how ...

RIVERSIDE, Calif. -- Over the last half a billion years, the ocean has mostly been full of oxygen and teeming with animal life. But earlier, before animals had evolved, oxygen was harder to come by.

Rutgers graduate student Heshani Pupulewatte (at right in yellow hard hat) collects water samples measuring conductivity, temperature and depth on a research ship in the Southern Atlantic Ocean. The ...

Iron can rapidly alter its molecular composition or state as it moves from the Earth’s crust to the ocean, and such changes determine whether iron is in a chemical form that diatoms and other ...
