Abstract: The present invention concerns a system for marine seismographic data acquisition, in particular for use in survey design. The invention provides a method for marine seismographic acquisition whereby subsea data and information can be collected using sea floor receivers and suspended receivers simultaneously. This is achieved by aligning the geometries of the two acquisition techniques and utilizing a system of wide-towed seismic sources that produce seismic energy on all the source point locations required to fulfil both acquisition methods.
