A Procedure to Edit Deep-Towed Navigation Data

Abstract

While data acquired from deep-towed seismic surveys offer the potential of greatly increased image resolution over the surface-towed approach, accurate positioning constitutes an important challenge which, if not performed accurately, could offset the benefits gained by the proximity between the source and the ocean bottom. We present here a new procedure that optimally determines relay and receiver positions at all times, using the Long Baseline acoustic navigation system. Navigation and seismic data were acquired during the October 2002 Cascadia Margin cruise.
