The paper describes a remarkable, symmetrical crater imaged using seismic reflection data, and buried below >300 m of sediment and 900 m of water in the outer Guinea Plateau 2/14
It shows characteristics consistent with an impact origin, including geometric relationships between crater depth and width, rim elevation, as well as a pronounced central uplift and intense deformation in the ‘brim’ outside of the central crater 3/14
