A method of seismic exploration, comprising: (a) positioning a seismic receiver boat at a location proximate a subsurface target, said seismic receiver boat pulling at least one seismic streamer therebehind, said at least one seismic streamer having a head end proximate to said receiver boat and a trailing end remote from said receiver boat; (b) positioning a first seismic source proximate to either said head end of said at least one seismic streamers or said trailing end of said plurality of seismic streamers; (c) positioning a second seismic source proximate an opposite end of said at least one seismic streamers from said first seismic source; (d) activating said first seismic source; (e) waiting a random length of time following said first seismic source activation and then activating said second seismic source, said random length of time being selected such that recorded seismic energy from said second source activation interferes with recorded seismic energy from said first source activation; (f) recording reflected seismic energy from said activation of said first seismic source and from said activation of said second seismic source via said at least one seismic streamer, thereby obtaining a plurality of seismic traces that record at least said first and second seismic source activations; (g) performing at least (a) through (f) a plurality of times at a plurality of different locations proximate to said subsurface target, thereby obtaining a blended source seismic survey comprised of a plurality of source activations, wherein said random length of time of (e) is related to a lowest frequency of interest in said blended source seismic survey, and said random length of time of (e) is chosen to be longer than a period corresponding to said lowest frequency of interest in said blended seismic survey; and, (h) using said blended source seismic survey to explore for hydrocarbons within said region of the subsurface, comprising: selecting a particular source activation from among said plurality of source activations in said blended source seismic survey; separating said selected source activation from said blended source seismic survey by using sparse inversion, thereby obtaining a single source gather; and, using said single source gather to explore for hydrocarbons within said region of the subsurface containing structural or stratigraphic features conducive to the presence, migration, or accumulation of hydrocarbons.
