Abstract: Systems and methods are provided for a marine seismic streamer usable underwater for marine seismic surveys. The marine seismic streamer includes: a lead-in section; at least one bird section; at least one data acquisition module; and at least one vibration module configured to vibrate the marine seismic streamer, wherein the lead-in section, the at least one bird section, the at least one data acquisition module and the at least one vibration module are connected together to form the marine seismic streamer.

Abstract: A system of designing and acquiring 3D marine seismic surveys such that the prevailing sea current is parallel or orthogonal to a major axis of the area to be surveyed. By steering the vessel and towed seismic source and receiver arrays through the water, heading into the sea current at some significant angle away from the sea current direction, then the resultant movement of the seismic source and receiver arrays will result in a much richer sampling and measurement of the earth's sub-surface by virtue of increasing the range of source-to-receiver azimuths available. By adopting this method, the final 3D seismic image of the subsurface will be more accurate and will be correctly focussed. Also line change times may be reduced significantly and the overall carbon footprint of the seismic survey may be lessened.
