The source ghost introduced by the sea surface reflection is usually considered noise which needs to be removed before imaging. We propose to utilize the source ghost in deblending as a natural blending code such that the end result is both deblended and deghosted. This method is easy to combine with other temporal source codes and provides an interesting alternative to deal with the current depth distributed source for a broadband solution. In this abstract, we discuss how to use the source ghosts in the case of lateral blending and vertical blending to deblend and deghost with illustrations of simple synthetic models. We applied the method to field data where two sources are blended in the same lateral position but at different depths. The results obtained show that it is possible to deblend and deghost in one step in the variable depth source setting.
