f Two-Ship Large Aperture Seismic Profiles - Application to Imaging through Basalt

We discuss the acquisition and processing of synthetic aperture seismic profiles, using two 2D seismic vessels to achieve continuous offsets to arbitrarily large offsets. The acquisition of high density, large aperture seismic data may allow the deep crustal structure to be studied in areas that have traditionally proven difficult to image using conventional seismic profiling techniques, such as those where high-velocity basalt flows or sills overlie sedimentary sections.
