Latest Chemical oceanography Stories
Deep under the Mediterranean Sea small animals have been discovered that live their entire lives without oxygen and surrounded by 'poisonous' sulphides.
Some regions of the deep ocean floor support abundant populations of organisms, despite being overlain by water that contains very little oxygen, but global warming is likely to exacerbate oxygen depletion and thereby reduce biodiversity in these regions, they warn.
As oxygen-deprived waters increase, they emit more greenhouse gasses into atmosphere.
Spore-like reproductive cysts of enigmatic organisms called acantharians rapidly sink from surface waters to the deep ocean in certain regions, according to new research.
Two studies provide clearer picture of how carbon cycle was dramatically affected long ago.
In a study published this week in Science, researchers describe a novel method for reconstructing past ocean chemistry using calcium carbonate veins that precipitate from seawater-derived fluids in rocks beneath the seafloor.
The increasing acidity of the world's oceans - and that acidity's growing threat to marine species - are definitive proof that the atmospheric carbon dioxide that is causing climate change is also negatively affecting the marine environment.
The impact on levels of carbon dioxide in the Earth's atmosphere by the decaying remains of a group of marine creatures that includes starfish and sea urchin has been significantly underestimated.
CO2 is being absorbed by the oceans, which increases seawater acidity (lowers the seawater pH).
A study published by US scientists on Sunday said pollution has caused the world's oceans to become noisier, causing more harmful effects to whales, dolphins, and other marine life.
Ocean acidification is the name that was given to the ongoing decrease in the pH of Earth’s oceans, a cause of the uptake of anthropogenic carbon dioxide from the atmosphere. About 30 to 40 percent of the carbon dioxide that is released by humans into the atmosphere dissolves into the lakes, oceans, and rivers. To maintain the chemical equilibrium, some of it reacts with the water to create carbonic acid. Some of these extra carbonic acid molecules react with a water molecule to provide a...
