A method for de-ghosting seismic data includes receiving seismic data corresponding to plural depth sources or plural depth receivers located at a first depth and a second depth below a geophysical surface, wherein the second depth is below the first depth, where the plural depth sources or plural depth receivers comprise a first seismic receiver located at the first depth and a second seismic receiver located at the second depth, or, a first seismic source located at the first depth and a second seismic source located at the second depth. The method also includes aligning primary reflections within the seismic data to provide improved seismic data. A corresponding system is also disclosed herein.
