Apparatus and methods for acquiring seismic data using a seabed seismic data cable positioned on a seabed are described, including controlling effect of water flow on the cable during data acquisition using fairing elements, which may be caused to extend from the cable generally transversely as water flows past the cable. Alternate paths for water underneath the cable may also be provided, reducing lift forces on the cable. It is emphasized that this abstract is provided to comply with the rules requiring an abstract, which will allow a searcher or other...
What is claimed is: 1. A faired seabed seismic cable comprising: (a) a cable having an exterior surface, the cable comprising a stress member in combination with one or more signal communication channels, and a plurality of seismic receiver units selected from the group consisting of: i) receiver clusters fastened to the cable at desired intervals, each cluster including at least two multi-axial, gimbal-supported seismic receivers symmetrically mounted about the axis of the cable; and ii) receiver housings comprising connecting means for connecting the ...
