By understanding the variability of methane release on time scales from hours to years and its dependence on oceanographic changes, we can quantify local and regional methane leakages.

To achieve this we will use hydro-acoustic methods for detecting and measuring gas bubbles in the water column. We will also select sites for long-term observatory stations in cooperation with national and international teams from the Norwegian Polar Institute and the Alfred-Wegener Institute for Polar Research. Additionally, a HUGIN Automated Underwater Vehicle (AUV) will help us conduct our measurements.

Measurements from the seabed, the air and from land stations, along with modelling analysis, will provide the link between potential sources of elevated methane concentrations and the reason for variations.

About the research area leader

Bénédicte Ferré is a physical oceanographer whose research activities span from sediment resuspension and transport to oceanographic data associated with methane release. She holds a PhD degree in marine science from the University of Perpignan, France.

Bénédicte was a post-doctoral researcher at the United States Geological Survey in Woods Hole, USA, before joining the Department of Geology at UiT The Arctic University of Norway as a researcher in 2008. She has contributed to numerous peer-reviewed publications.
