Climate change in real time: Incredible animations reveal changing ocean acidity
2015-02-17 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Daily Mail: Satellite images are being used to monitor how ocean acidification is changing the world's seas. For the first time, scientists have been able to obtain a global picture of how rising carbon dioxide levels in the atmosphere are affecting the oceans. Using thermal cameras and microwave sensors mounted on satellites orbiting 435 miles above Earth, the experts said it's possible to assess which areas of the ocean are most at risk of acidification. Scientists have used satellite data to map...

Space-Based Measurments Can Track Global Ocean Acidity, Researchers Say
2015-02-16 20:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: An international team of scientists has developed new methods for studying the acidity of the oceans from space, according to research published in the journal Environmental Science and Technology. Currently, scientists must rely on measurements taken from research vessels and sampling equipment deployed in oceans to determine acidity which rises as the oceans absorb CO2 from the atmosphere but this approach is expensive and geographically limited. The new techniques use satellite-mounted thermal...
Level of Plastic Waste in the Ocean Higher than Previously Thought
2015-02-13 16:27:00| Waste Age
<a href="http://www.pbs.org/">PBS</a> About 8 million metric tons of plastic waste makes its way into the oceans each year, according to a study published today by a group of scientists at the UC Santa Barbaras National Center for Ecological Analysis and Synthesis. The number is expected to increase unless countries are able to turn off the faucet, Kara Lavender Law, one author of the study, said. read more

Eight Million Tons of Plastic Dumped in Ocean Every Year
2015-02-12 22:02:00| Climate Ark Climate Change & Global Warming Newsfeed
National Geographic: Scientists have come up with a new way to measure ocean trash-and the numbers are even worse than thought. In 2010, eight million tons of plastic trash ended up in the ocean from coastal countries-far more than the total that has been measured floating on the surface in the ocean's "garbage patches." That's the bad news. The even worse news is that the tonnage is on target to increase tenfold in the next decade unless the world finds a way to improve how garbage is collected and managed. The...

Is pH a Red Herring for Ocean Acidification?
2015-02-07 16:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: In 2007, the owners of Whiskey Creek oyster hatchery on the Oregon coast lost almost all of their larvae -- and had no idea why. The only clue was that the larval die-offs often occurred during intense upwelling events, when deep, acidic waters replace surface waters blown offshore. The next year, the hatchery owners turned to Burke Hales, a biogeochemist at Oregon State University in Corvallis, who dove into the ocean's complex carbon chemistry. Ocean acidification was clearly a growing concern....
