Ocean acidification is the lowering of seawater pH over time, as the ocean absorbs carbon dioxide (CO 2) from the atmosphere. The pH scale is used to measure how acidic or basic a water-based solution ...

Pioneering techniques that use satellites to monitor ocean acidification are set to revolutionise the way that marine biologists and climate scientists study the ocean. This new approach, that will be ...

Scientists have known for decades that soaring atmospheric carbon dioxide emissions are causing changes in ocean chemistry, threatening marine life and ecosystems. In June 2025, a study found that ...

Ocean acidification is sinking into marine regions as deep as 1500 metres, posing new threats to organisms like sea butterflies, sea snails and cold-water corals. The ocean is the largest natural sink ...

A pair of environmental physicists at the Institute of Biogeochemistry and Pollutant Dynamics, ETH Zurich, has built a 3D model of the world's oceans and their currents to learn more about the depths ...

The ocean is the lifeblood of our planet—producing over half of the world’s oxygen, regulating global temperatures, and supporting millions of species. Yet today, marine ecosystems are under severe ...

A new assessment finds that the world’s oceans crossed the safe threshold for acidification in 2020, breaching a key planetary boundary and posing serious threats to marine life. Ocean acidification ...

This is read by an automated voice. Please report any issues or inconsistencies here. PORTLAND, Maine — Sharks are the most feared predators in the sea, and their survival hinges on fearsome teeth ...

Princeton University and Xiamen University researchers report that in tropical and subtropical oligotrophic waters, ocean acidification reduces primary production, the process of photosynthesis in ...

Clams and other molluscs are under threat. As oceans gradually acidify due to rising carbon dioxide (CO 2) emissions, some of these marine organisms will find it harder to build their shells or ...

The Soil Moisture and Ocean Salinity (SMOS) mission makes global observations of soil moisture over Earth’s landmasses and salinity over the oceans. Variations in soil moisture and ocean salinity are ...

While the livelihoods of more than three billion people depend on oceanic resources, the ocean also provides a large fraction of the oxygen we breathe and absorbs greenhouse gases, mitigating their ...
