摘要

Method for acquiring data in a plurality of positions su00ecsmicos scattered over an area at the bottom of the sea, equipment of guide to direct a purchasing unit su00ecsmica towards a target position located on the bottom of the sea, and equipment and system for acquisition su00ecs Mica from the bottom of the sea.The invention relates to a method for seismic data acquisition in a plurality of positions scattered over an area of the bottom of the sea.The method according to the invention, comprises the following steps: transmission of acoustic waves in the water layer above said zone by means of a plurality of sources for each of those positions of the acquisition, release from the surface of an equipment. Seismic acquisition.With this equipment must include a unit of seismic acquisition equipment and a guide adapted to receive separate acoustic signals derived from the above-mentioned sources and control the trajectory according to the acoustic signals received in order to guide the Said equipment within the meaning of that position, carry out the seismic acquisition.- make the acquisition equipments rise to the surface, recovering the acquisition equipments on the surface.
