A large number of giant methane plumes have recently been detected in the Arctic Sea. The methane is being released from the sediment in the deep ocean and as methane is twenty times more potent as a greenhouse gas than carbon dioxide, this raises concerns about a possible run-away effect of global warming.
Drs Silvana Cardoso and Nicola Mingotti of the Fluids and Environment Group are working on how to understand the complex behaviour of such plumes. Experiments and theoretical modelling will develop fundamental knowledge so that we can move towards predicting or controlling the flows.
The group's research is funded by the Leverhulme Trust and Dr Cardoso's recent article in the Trust's newsletter stood out above the rest so that it was included in the Annual Review 2015 (published in spring 2016).
The article describes how the research will shed light on the giant methane plumes’ spreading and mixing behaviour, helping us to understand their impact on the environment.
