Modern ocean acidification is outpacing ancient upheaval, study suggests
Some 56 million years ago, a massive pulse of carbon dioxide into the atmosphere sent global temperatures soaring. In the oceans, carbonate sediments dissolved, some organisms went extinct and others evolved.
Dinosaur-killing impact acidified oceans: study
The space rock that smashed into Earth 65 million years ago, famously wiping out the dinosaurs, unleashed acid rain that turned the ocean surface into a witches' brew, researchers said Sunday.
Ocean acidification leaving fish in the dark
Increasing carbon dioxide in the world's oceans could hamper fishes' eyesight, slowing their reaction times and leaving them vulnerable to predators or unable to hunt, new research has shown.
Sponges erode coral reef under acidification scenarios
Ocean warming and acidification are leading to an increase in the rate of sponge biomass and bioerosion.
Rising ocean acidification leads to anxiety in fish
A new research study combining marine physiology, neuroscience, pharmacology, and behavioral psychology has revealed a surprising outcome from increases of carbon dioxide uptake in the oceans: anxious fish.
Arctic study shows key marine food web species at risk from increasing carbon dioxide
A research expedition to the Arctic, as part of the Catlin Arctic Survey, has revealed that tiny crustaceans, known as copepods, that live just beneath the ocean surface are likely to battle for survival ...
Unprecedented rate and scale of ocean acidification found in the Arctic
Acidification of the Arctic Ocean is occurring faster than projected according to new findings published in the journal PLoS One. The increase in rate is being blamed on rapidly melting sea ice, a proces ...
Carbon-sequestering ocean plants may cope with climate changes over the long run
A year-long experiment on tiny ocean organisms called coccolithophores suggests that the single-celled algae may still be able to grow their calcified shells even as oceans grow warmer and more acidic in ...
Dissolving brittle stars hint at implications of ocean acidification
(Phys.org) —Under the sea ice of Explorers Cove, Antarctica, is a startling array of life. Brittle stars, sea urchins and scallops grow in profusion on the seafloor, a stark contrast to the icy moonscape ...
Coccoliths thrive despite ocean acidification
Ocean acidification is damaging some marine species while others thrive, say scientists. An international team studied the effect of ocean acidification on plankton in the North Sea over the past forty years, ...
Scientists sound alarm at Arctic Ocean's rapid acidification
Scientists expressed alarm on Monday over the rapid acidification of the Arctic Ocean caused by carbon dioxide emissions, which could have dire consequences on the region's fragile ecosystem.
Acidifying oceans may be harmful to porcelain crabs
(Phys.org) —As the world's oceans soak up carbon dioxide from an atmosphere increasingly polluted by fossil fuels, seawater will become more acidic. Two new studies by San Francisco State University students ...
Large plastic bags in unique experiment to study ocean acidification
To study the effects of ocean acidification, ten huge plastic containers called mesocosms are placed in the Gullmar Fjord in Sweden. The project is unique: mesocosms of this size have never been used for ...
Survival of the fittest: Ocean acidification produces winners and losers
(Phys.org)—As atmospheric carbon dioxide levels continue to increase, the ocean absorbs more carbon dioxide. This absorption comes at a cost, since it makes the ocean more acidic. An acid ocean will affect ...
