ScienceDaily: New research shows that human pollution of the atmosphere with acid is now almost back to the level that it was before the pollution started with industrialisation in the 1930s. The results come from studies of the Greenland ice sheet and are published in the scientific journal, Environmental Science and Technology. The Greenland ice sheet is a unique archive of the climate and atmospheric composition far back in time. The ice sheet is made up of snow that falls and never melts, but rather remains...

Available in 16 different models, PAL-BX/ACID Series measures sugar and acidity level in fruit juices, milk, beer, yogurt, sake, or vinegar. Devices measure total acidity in sample and convert it into citric, tartaric, malic, acetic, or lactic acid concentrations, depending on unit. Unlike traditional titration method, PAL-BX/ACID Series requires no reagent. Measuring 55 x 31 x 109 mm, IP65-rated refractometers feature backlit screen and measurement time of 3 seconds.

New maps reveal global ocean acidity
2015-02-17 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: A global look at ocean pH reveals that the water is more alkaline (basic) in the open ocean than in many coastal regions. The more alkaline the water is, the better poised it is to resist ocean acidification. Ocean acidification can now be seen from space, highlighting an ongoing danger of climate change and revealing the regions most at risk. Seawater absorbs about a quarter of the carbon dioxide, a greenhouse gas, that humans release into the atmosphere each year, mostly from the burning...

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...
