Can carbon dioxide be stored safely offshore?

Storage of carbon dioxide in the offshore sea bed as part of a Carbon Capture and Storage (CCS) strategy is often discussed as a means to reduce further the increase of carbon dioxide to the atmosphere. Funded by the European Union, the ECO2 project developed recommendations for the selection and monitoring of submarine storage sites as well as an approach to a sound environmental risk assessment (ERA). 27 partner institutions from nine European countries cooperated in the project, among these the Norwegian Institute for Water Research. The outcome of ECO2 helps to adjust CCS regulations and to operate sub-seabed CO2storage sites more safely.

Waters acidified by air pollution have recovered as predicted

Waters acidified by air pollution have recovered as predicted

Back in 1999, a group of scientists predicted how changing air pollution levels would affect the acidity of lakes and rivers in Europe in 2010 using a computer model. A follow up study has now gathered actual measurements of these waters to see if the predictions came true. The observations show that most of the rivers and lakes did recover from acidification, as forecast by the model, and demonstrate the model’s value in predicting future water chemistry.
