Project overview

The NERC-funded Characterisation of Major Overburden Leakage Pathways above Sub-sea floor CO2 Storage Reservoirs in the North Sea (CHIMNEY) project investigated the risks of leaks from storing carbon dioxide (CO2) under the seabed. CHIMNEY involved investigators from the University of Southampton, National Oceanography Centre in Southampton (NOC), and University of Edinburgh. These investigators worked closely with project partners GEOMAR, Lawrence Berkeley National Laboratory, CGG and Applied Acoustics. A multi-channel seismic dataset, together with multibeam bathymetry was acquired during RRS James Cook cruise JC152 (August - September 2017), around the Scanner Pockmark Complex in the North Sea.
