USC scientists are exploring how the sandy seafloor off the Southern California coast takes up CO2 and helps protect the long ...

2. It surfaced decades before scientists expected to see it. What is ocean acidification? Put simply, it’s a process that lowers the pH of the oceans, causing them to become more acidic and ...

These creatures create shells from calcium carbonate, which dissolves when exposed to acid in a chemical process that creates even more carbon dioxide and, likewise, increases the acidification ...

Ocean acidification combined with warming of the world oceans and loss of oxygen is having a severe impact on key Arctic marine species such as polar cod in the Barents Sea, according to a new ...

Acidification makes it more difficult for marine animals to produce skeletons and shells, and puts the essential ocean habitat, coral reefs, at risk of eroding faster than they can be rebuilt.

Scientists know that, as humans keep emitting excess CO2, the oceans are absorbing the gas and becoming more acidic, a process known as ocean acidification. Ocean water temperatures are also rising.

But with coastal upwelling, a process that can bring acidic deep-ocean water to the surface, some coastal environments already occasionally see higher levels of acidification.

The ocean is both a source of oxygen and a sink for carbon dioxide (CO 2). It absorbs about one fourth of all CO 2 emissions. While this leaves less CO 2 in the atmosphere and mitigates climate change ...

Ocean acidification reduces thallus strength in a non-calcifying foundation seaweed. Current Biology, 2023; 33 (18): R941 DOI: 10.1016/j.cub.2023.07.056 ...

"Ocean acidification scares debunked," reads the text over a May 21, 2025 video posted to X by The Heartland Institute, a US free-market think tank (archived here), which AFP has investigated in ...

The ocean plays a vital role in protecting the planet, absorbing about 31% of the carbon dioxide (CO2) released by human activity, storing it in its ...
