This work was conducted in the North Sea in a water depth of 120 m during a control release of CO2 (https://www.stemm-ccs.eu/). The experiment simulated the unlikely event of a marine carbon capture and storage facility leaking and gas bubbling from the sea floor. In the experiment CO2 was released from a pipe drilled to 3 m below the sea bed. We demonstrated that it is possible to monitor the movement of the gas through the upper sediments to the water using a sub-bottom profiler (a sonar system which “sees into” the sea floor) mounted on an autonomous underwater vehicle.
