Acidic ocean eating away at 'sea butterflies' off West Coast
2014-05-01 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
NBC News: Acidic waters along the West Coast are dissolving the shells of tiny sea snails that are a food source for salmon, herring and other fish, scientists reported Wednesday, and conditions are worse than they expected. Caused by increasing carbon dioxide in the atmosphere, the oceans growing acidity threatens not just to the creatures at the bottom of the food chain, but seafood-eating higher life forms such dolphins, whales and humans. Oceans absorb carbon dioxide from the atmosphere, and scientists...
Ocean Acidification Could Make Fish Lose Their Fear Of Predators, Study Finds

ThinkProgress: Add "losing fear of predators" to the long list of impacts acidifying oceans could have on fish and other marine life. A new study published in Nature Climate Change has found that elevated CO2 levels in marine waters make reef fish attracted to the smell of their predators, rather than being repelled. Researchers looked at multiple species of reef fish living near natural volcanic CO2 seeps in Papua New Guinea, an environment the study says is acidified to levels comparable to projections of...
Study resolves controversy over nitrogen's ocean 'exit strategies'
2014-04-11 08:00:00| Climate Ark Climate Change & Global Warming Newsfeed
PhysOrg: A decades-long debate over how nitrogen is removed from the ocean may now be settled by new findings from researchers at Princeton University and their collaborators at the University of Washington. The debate centers on how nitrogen-one of the most important food sources for ocean life and a controller of atmospheric carbon dioxide-becomes converted to a form that can exit the ocean and return to the atmosphere where it is reused in the global nitrogen cycle. Researchers have argued over which...

Into the abyss: Scientists explore one Earth's deepest ocean trenches
2014-04-11 02:37:00| Climate Ark Climate Change & Global Warming Newsfeed
TG Daily: What lives in the deepest part of the ocean--the abyss? A team of researchers funded by the National Science Foundation (NSF) will use the world's only full-ocean-depth, hybrid, remotely-operated vehicle, Nereus, and other advanced technology to find out. They will explore the Kermadec Trench at the bottom of the Pacific Ocean. The trench, located off New Zealand, is the fifth deepest trench in the world. Its maximum depth is 32,963 feet or 6.24 miles (10,047 meters). It's also one of the coldest...

Ocean Temperature Analysis Suggests Recent Slowdown in Warming is Fleeting
2014-04-07 21:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Climate researchers taking a new perspective on the available data suggest the recent "slowdown" in the warming rate of the Northern Hemisphere is likely a fleeting reality. Writing in the journal Geophysical Research Letters, a team of researchers from Penn State University report that internal variability of a natural temperature phenomenon known as the Atlantic multidecadal oscillation (AMO) may be the cause for the apparent slowdown of warming in the Northern Hemisphere. "Some researchers...
