The present invention generally relates to seismic data acquisition and more specifically to ocean bottom seismic data acquisition systems. An ocean bottom seismic cable [130, 200] may include a first section [175, 275, 310] comprising a plurality of seismic sensors [110], wherein the first section [175, 275, 310] is positioned on a floor [111] of a body of water in an area where there are no or substantially no obstructions [210, 350]. The seismic cable [130, 200] may also include a second section [176, 276, 320] coupled to the first section [175, 176, 310], wherein the second section [176, 276, 320] is positioned above or overlays an obstruction [210, 350], and wherein the second section [176, 276, 320] does not include seismic sensors [110]. |
