Claim 8:
9. A method for processing seismic data acquired over a body of water, the method comprising:
receiving sparse node seismic data acquired with plural seismic nodes distributed over the ocean floor, with an inline distance/between adjacent nodes among the plural nodes;
receiving mini-streamer spread data acquired with plural mini-streamers towed with a vessel above the plural seismic nodes with a distance m along each mini-streamer between adjacent channels, each channel including one or more sensors configured to acquire a trace of the mini-streamer spread data, the mini-streamer having N channels where N≤3l/m;
combining the sparse node seismic data and the mini-streamer spread data; and
processing the combined sparse node seismic data and mini-streamer spread data to generate an image of the subsurface.
