Rise in ocean acidity makes fish anxious, study finds

LA Times: Ocean acidification could alter the behavior of fish and make them more anxious, a new study says. The finding came in an experiment by researchers interested in the neurological effects of the shift in the chemistry of seawater that is happening as the ocean takes up carbon dioxide that has built up in the Earth's atmosphere from human activity. In a laboratory, scientists put one group of young rockfish, a common species along the California coast, in normal seawater and put another group...
Reefs may help in fight against ocean acidity
2013-11-29 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Royal Gazette: While many scientists have been warning about potentially dire consequences of the oceans increasing acidity, a recent scientific paper suggested that coral reefs such as those around Bermuda might actually help offset ocean acidification. They point out the ocean is the largest natural sink for carbon dioxide (CO2), absorbing one quarter to one third of the CO2 produced by humans. However, as the amount of CO2 in the atmosphere increases, fundamental properties of seawater chemistry are also...

New study of the Arctic Ocean finds alarming increase in acidity
2013-09-15 15:31:00| Climate Ark Climate Change & Global Warming Newsfeed
Environmental News Network: If you ever had a marine aquarium (or a swimming pool) you know that it is very important to keep the level of acidity (ph) within a narrow range for optimum results. In the case of the pool, to minimize corrosion of the metal parts in a heater and to reduce damage to the pool lining or paint. In the case of the aquarium, the ph is directly related to the health of coral and fish. The ocean is no different. Acidity is an important parameter that relates to many other parameters including the health...

New Prize is Created to Improve Measurements of Ocean Acidity
2013-09-10 17:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: Philanthropist Wendy Schmidt is offering $2 million in prize money to inventors who can develop inexpensive and easily deployable sensors to measure ocean acidification. The Wendy Schmidt Ocean Health X Prize is offering $1 million to the team that invents the most accurate sensors to measure the oceans acidity and $1 million to the team that devises the most affordable and easy-to-use sensors. Biologist Paul Bunje, a senior executive for oceans at the X-Prize Foundation, said that because current...

Rising ocean acidity will exacerbate global warming
2013-08-25 12:05:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature: The slow and inexorable increase in the oceans acidity as they soak up carbon dioxide from the atmosphere could itself have an effect on climate and amplify global warming, according to a new study. Acidification would lead certain marine organisms to emit less of the sulphur compounds that help to seed the formation of clouds and so keep the planet cool. Atmospheric sulphur, most of which comes from the sea, is a check against global warming. Phytoplankton -- photosynthetic microbes that drift...
