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.

Rising carbon dioxide emissions are not only increasing global temperatures, but are also making the oceans more acidic, threatening marine organisms. Here is a videographic explaining ocean ...

The oceans are becoming more acidic, and it could affect some of the food we eat. There is growing concern among the scientific community that ocean acidification is reaching a critical point and has ...

B.C.’s ocean acidification and hypoxia action plan, released in 2023, notes that ocean acidification and the related phenomenon of hypoxia (low oxygen zones in the ocean) “poses a significant ...

Right now, the pH of open waters near Hawaii commonly hovers around 8, and ocean acidification models forecast a pH drop of 0.2 or more over the next 100 years, said Carrington.

'Ocean acidification is a crisis we cannot see,' said Professor Helen Findlay, the lead author of the study. 'But its fingerprints are all over our coastlines, hatcheries and ecosystems.

If a change in ocean pH of 0.25 over a few hundred to a few thousand years following the Chicxulub impact caused such a dramatic die-off of marine life, the projected ocean acidification we could ...

“Ocean acidification is happening globally,” said Jim Christian, research scientist with Fisheries and Oceans Canada. “It affects all kinds of organisms,” said Christian, who works at the ...

Ocean acidification is affecting the shells and sensory organs of young Dungeness crabs in West Coast waters, posing a threat to B.C.’s second most valuable seafood export. A study published in ...

The new study found four of the world’s seven ocean basins have crossed the planetary boundary for ocean acidification. Polar regions have been most widely affected: Nearly 87 per cent of the Southern ...
