In three dimensions ([[:File:3D Seismic.jpeg|Figure 3]]). For his register the sources and receptors ubicates across perpendicular lines each in the interest area, having as result a seismic data volume, with bigger density respect 2-D seismic, and provide better ubication of the structures. This method generates seismic cubes according to the deep, the length of the seismic line and the hydrophones arrangement wide.  

Surveying in three dimensions ([[:File:3D Seismic.jpeg|Figure 3]]), registers the sources and receptors ubicates across perpendicular lines in each interest area, which results in a seismic data volume, with bigger density than r2-D seismic, and provides better ubication of the structures. This method generates seismic cubes according to the depth and length of the seismic line and the width of the hydrophones arrangement.

Consist in the repetition of a 3D seismic survey in exactly the same original area, after a determinated time. In consequence, the time function is added to a 3d cube.
