Acidification affects future all sea life

IOM Today: In 2010, a report by the US National Research Council found that pH levels the level of acidity or alkalinity at the oceans surface had fallen from a measure of 8.2 in pre-industrial times, to 8.1 in modern times. This has taken place as something between a quarter and a third of man-made CO2 emissions have been added to the natural absorption rates of those oceans. Since pH is measured on a logarithmic scale, this means that there has been a 10-fold decrease in alkalinity or to put...
Southwest, Southeast Alaska face highest risks from ocean acidification
2014-07-30 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Alaska Public Media: Coastal communities in Alaska that depend on fisheries were warned Tuesday to prepare for the impacts of ocean acidification. A study from federal agencies says many of the science questions remain unanswered but changes are already happening. The first concern is likely shellfish, because when the chemistry of the ocean changes, it`s harder for them to form shells. But which commercial shellfish and when they might be affected and in what waters are questions they can`t answer yet. But what the...

In Prince William Sound, remote-controlled gliders measure ocean acidification
2014-07-15 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Alaska Dispatch: Ocean chemists are calling it revolutionary technology as unmanned gliders track how melting glaciers may be intensifying corrosive waters in Prince William Sound. Its been hugely successful. Weve flown these things all over inside and outside of Prince William Sound, weve had great control over them, weve been able to move them to exactly where we want them to be. They are making thousands of measurements all over, said Jeremy Mathis, director of the Ocean Environment Research Division...

Huffman warns of economic, ecological damage tied to ocean acidification
2014-06-17 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Marin News: Job losses, destruction of habitat and the collapse of the shellfish industry is in the offing if steps are not taken to cope with ocean acidification brought about by pollution in the atmosphere, U.S. Rep. Jared Huffman warned Monday. Huffman, D-San Rafael, visited the University of California at Davis Bodega Marine Laboratory to discuss the issue with researchers, business owners and fishermen. "Ocean acidification will have very far-reaching effects on our food web, our economy and our ecosystem."...

Mediterranean Sea facing double threat of warming and acidification
2014-06-13 15:07:00| Climate Ark Climate Change & Global Warming Newsfeed
Blue and Green: The marine species of the Mediterranean Sea, as well as the livelihoods and lifestyles of millions of people that depend on them, are being threatened by a manmade combination of global warming and ocean acidification. In a new study, coordinated by the Autonomous University of Barcelona (UAB), researchers warn that the sea is both warming and acidifying at unprecedented rates, with carbon dioxide emissions to blame. "We knew next to nothing about the combined effects of warming and acidification...
