Ocean acidifcation

Our oceans are absorbing about one-third of the carbon dioxide in the atmosphere. As a result, they are becoming more acidic. Professor Abby Smith, from the University of Otago, is researching the role that bryozoans can play in monitoring these changes in pH. DISCUSSION Discuss what is meant by the term ‘canary in the coal mine’?
