Posted on OA: 17 Nov 2013 — By IOC-UNESCO Net CO2 absorption by the world’s oceans is known to benefit human-kind by reducing the concentration of this greenhouse gas in the atmosphere. But as CO2 dissolves in seawater carbonic acid is formed, causing the ocean to acidify at rates not seen for

Oceanic Acidification Ruining Digestion of Sea Urchins
Posted on Nature World News: 16 Nov 2013 — First demonstration that ocean’s CO2 uptake can impair digestion in a marine animal Researchers from Sweden and Germany have found that climate change and ocean acidification is ruining the digestive systems of marine animals. They conducted the study on a larval
Expert assessment: Ocean acidification may increase 170 percent this century
Posted on Phys.Org: 13 Nov 2013 In a major new international report, experts conclude that the acidity of the world’s ocean may increase by around 170% by the end of the century bringing significant economic losses. People who rely on the ocean’s ecosystem services – often in developing countries –
Study: ocean acidification killing oysters by inhibiting shell formation
Posted on EPOCA: 12 Jun 2013 CORVALLIS – For the past several years, the Pacific Northwest oyster industry has struggled with significant losses due to ocean acidification as oyster larvae encountered mortality rates sufficient to make production non-economically feasible. Now a new study led by researchers at Oregon State University
Assessing physiological tipping point of sea urchin larvae exposed to a broad range of pH
Posted on EPOCA: 11 Jun 2013 Our ability to project the impact of global change on marine ecosystem is limited by our poor understanding on how to predict species sensitivity. For example, the impact of ocean acidification is highly species-specific, even in closely related taxa. The aim of this study
