This ocean post is from the PBS Correlations archive, originally published on November 6th, 2007. You may have been hearing all the hullabaloo over ocean acidification.

New insights from 150 years suggest that oceans are at present a 'ticking bomb' that needs to be dealt with quickly.

Ocean acidification plus warming can be deadly to many species of plankton. Since so much of all of Earth’s life is found in the ocean, and it all depends on plankton, this could be a gigantic ...

Scientists had determined that ocean acidification enters this danger zone or crosses this planetary boundary when the amount ...

The oceans could become so filled with carbon dioxide that scientists are proposing a new factor to measure their capacity ...

By Sean Mowbray Ocean health is moving into a danger zone, with rampant human-caused carbon dioxide emissions having already pushed ocean acidification levels beyond safe limits in large swaths of the ...

Scientists call ocean acidification "the other carbon problem." When the ocean absorbs carbon dioxide from the atmosphere, it raises the pH of the water making it acidic.

And ocean acidification is set to continue as the water absorbs more CO2. “Even if we were able to stop CO2 emissions immediately, we would still – for a couple of hundred of years or so ...

That boundary, they suggest, is ocean acidification, and it happens when the amount of calcium carbonate in seawater hits a 20% reduction relative to levels present before the Industrial Revolution.

Of course, it’s best if we don’t put that to the test. The best way to protect marine ecosystems from ocean acidification is to limit acidification, says Roggatz.

Princeton University and Xiamen University researchers report that in tropical and subtropical oligotrophic waters, ocean acidification reduces primary production, the process of photosynthesis in ...
