1. A method comprising:
- acquiring particle motion data from a plurality of particle motion sensors while in tow during a seismic survey of a geologic structure, the particle motion data representing particle motions sensed by the particle motion sensors due to at least one seismic event;
during the seismic survey, processing the particle motion data to determine whether at least some portion of the particle motion data is inadequate for a seismic data processing application that relies on the at least some portion of the particle motion data; and
selectively processing the at least some portion of the particle motion data using the seismic data processing application to determine a characteristic of the geologic structure based at least in part on the determination whether at least some portion of the particle motion data is inadequate for the seismic data processing application.

Abstract
A technique includes acquiring particle motion data from a plurality of particle motion sensors while in tow during a seismic survey. During the seismic survey, the particle motion data are processed without deghosting the particle motion data to determine whether at least some portion of the particle motion data is inadequate for an application that relies on the particle motion data.
