Abstract: Method and marine mixed-spread seismic acquisition system that includes a single first streamer towed by a first vessel in water; a source towed by the first vessel and configured to generate seismic waves; and plural autonomous underwater vehicles (AUVs) configured to record reflected seismic waves. The single first streamer includes plural seismic receivers configured to also record the reflected seismic waves.

Abstract: Seismic survey data is processed to simultaneously attenuate noise and interpolate the data. A frequency slice of one of a plurality of overlapping subvolumes formed from the seismic survey data is selected. A noise reduced, interpolated frequency slice is generated by jointly minimizing a nuclear norm of a trajectory matrix data corresponding to the desired data and an L1 norm of erratic noise in the selected frequency slice. The noise reduced and interpolated frequency slice is combined with at least one other frequency slice to produce a noise reduced, interpolated frequency subvolume of the surveyed area. The noise reduced, interpolated frequency subvolume is combined with at least one other noise reduced, interpolated frequency subvolume to produce noise reduced, interpolated seismic data of the surveyed area.
