    摘要: A technique for processing seismic data acquired in a seismic survey conducted in the presence of a rough sea includes receiving a first dataset that is derived from data acquired by a first set of seismic sensors generally towed at a first depth in the seismic survey and receiving a second dataset that is derived from data acquired by a second set of seismic sensors generally towed at a second depth that is different than the first depth in the seismic survey. The first dataset is indicative of at least pressure measurements, and the second dataset is indicative of at least crossline particle motion measurements. The technique includes determining crossline particle motion measurements in the presence of a relatively flat sea surface based at least in part on the crossline measurements that are indicated by the second dataset and the pressure measurements that are indicated by the first dataset.

    摘要: A technique includes obtaining pressure data that was acquired by seismic sensors towed as part of a three-dimensional spread of streamers and obtaining particle motion data, which are indicative of particle motion at locations of the sensors. The technique includes estimating cross-line spectra of the pressure data based at least in part on the pressure data, and the technique includes deghosting the particle motion data based at least in part on the estimated cross-line spectra.
