Increased acidity not an even test for coral reefs

Coral reefs can both positively and negatively influence the acidity of their surrounding seawater. That is the take-home message of two papers recently published in the international journal Global Change Biology, by a group ...

Fukushima nuke pollution in sea 'was world's worst'

France's nuclear monitor said on Thursday that the amount of caesium 137 that leaked into the Pacific from the Fukushima disaster was the greatest single nuclear contamination of the sea ever seen.

Earth is having a bad acid trip, study finds

Earth may be overdosing on acid - not the "turn on, tune in, drop out" kind, but the "kill fish, kill coral, kill crops" kind. And it's shaping up to be a very bad trip.

Acidifying oceans could hit California mussels, a key species

Ocean acidification, a consequence of climate change, could weaken the shells of California mussels and diminish their body mass, with serious implications for coastal ecosystems, UC Davis researchers will report July 15 ...

Desalinating seawater with minimal energy use

At a pilot facility in Singapore, Siemens has cut the energy needed to desalinate seawater by more than 50 percent. The plant processes 50 cubic meters of water per day, consuming only 1.5 kilowatt-hours of electricity per ...

Antarctic icebergs help the ocean take up carbon dioxide

The first comprehensive study of the biological effects of Antarctic icebergs shows that they fertilize the Southern Ocean, enhancing the growth of algae that take up carbon dioxide from the atmosphere and then, through marine ...

CO2 makes life difficult for algae

The acidification of the world's oceans could have major consequences for the marine environment. New research shows that coccoliths, which are an important part of the marine environment, dissolve when seawater acidifies.
