A method and apparatus for operating a single source vessel along a survey path, the source vessel towing a source and a first plurality of streamers; operating a streamer vessel along the survey path, the streamer vessel towing a second plurality of streamers; actuating the source; acquiring near-offset data with a first plurality of receivers; and acquiring long-offset data with a second plurality of receivers. A system includes a source vessel coupled to: a source; and a near-offset survey spread; a streamer vessel coupled to a long-offset survey spread, wherein a streamer spacing density of the long-offset survey spread is no greater than a streamer spacing density of the near-offset survey spread; and a survey plan including navigation information for the source vessel and the streamer vessel, wherein the navigation information directs the source vessel and the streamer vessel along a common survey path while the source is actuated.
