Abstract
Techniques are disclosed relating to reducing noise in marine seismic survey data. A shot-by-shot depth migration of recorded marine seismic survey data that includes multiples wavefields indicative of surface reflections may be performed. Post-migration data generated by the migration may include angle information derived from the multiples wavefields. Attributes of the marine seismic survey data may be corrected using the angle information in order to identify a potential sub-surface structure.
