A method is proposed for acquiring seismic data relative to an area of the subsoil, wherein at least one seismic source (107) is moved and seismic waves are emitted in successive shooting positions of the source so as to illuminate said area of the subsoil, and the signals resulting from this emissions are picked up using a set (101) of cables (110) having a substantially zerobuoyancy and provided with receivers (106). The cables (110) have a substantially zero speed or a speed substantially slower than the source (107) in the terrestrial reference frame. And said successive shot positions are determined as a function of the position of the receivers (106) relative to the terrestrial reference frame to optimize at least one quality criterion relating to the set of seismic signals acquired by the receivers (106) in respect of said area. Such a method enables improved seismic data acquisition. |
