Researchers from around the world took part in a first-of-its-kind training course focused on the ecological impacts of Ocean Alkalinity Enhancement (OAE), an emerging method for carbon dioxide (CO 2) ...

New clues from ancient seas are reshaping what we know about mass extinction and the future of our oceans. In a recent ...

A prehistoric carbon spike turned oceans deadly and wiped out marine life. Scientists say today’s CO₂ rise could cause the ...

WE’VE BEEN free to pollute ever since we started using fossil fuels more than 145 years ago. Since then, we have been ...

A new model accounting for the role of bubbles in air-sea gas exchanges suggests that ocean carbon uptake is more variable than previously thought.

The ocean absorbs carbon from the atmosphere, but exactly how much is uncertain. For instance, estimates from the 2023 Global Carbon Budget ranged from 2.2 billion to 4 billion metric tons of ...

New advancements in satellite technology are transforming how we understand the role oceans play in regulating carbon dioxide (CO2) levels in Earth’s atmosphere. While the oceans have long served as a ...

A startup called Gigablue claims to have reached a milestone by selling 200,000 carbon credits for its ocean-based carbon capture technology.

A new study has revealed that small but mighty zooplankton—including copepods, krill, and salps—are key players in the Southern Ocean's ability to absorb and store carbon.

Ocean health is moving into a danger zone, with rampant human-caused carbon dioxide emissions having already pushed ocean acidification levels beyond safe limits in large swaths of the marine ...

Ancient carbon surges depleted ocean oxygen and stalled marine life, and new research warns today’s emissions could cause a similar crisis.

Massive natural carbon releases 300 million years ago caused sharp declines in ocean oxygen, disrupting marine life. Scientists uncovered five such "burps" using sediment cores and climate ...
