Ocean acidification: Coral core reveals dropping pH values in South Pacific

Our oceans absorb more than 40% of the anthropogenic greenhouse gas CO2 from the atmosphere, which leads to a drop in the pH value of the seawater. Until recently, reliable long-term measurements and historical data to illustrate the influence of CO2 uptake on the pH value of the seas have been insufficient. A team of scientists has now analysed a coral core to show how the pH value in the Southern Pacific has changed since pre-industrial times. The study was published in the journal “Nature Communications”. (Mehr in: Pressemitteilungen – idw – Informationsdienst Wissenschaft)
