1. A method for controlling marine seismic system with studies with several vessels, including the first vessel, having a recording and towing system, at least one tape drive, comprising seismic sensors, and the second vessel, comprising at least one seismic source performing shots , wherein the seismic data received by said seismic sensors, said recording system are recorded, wherein the recorded seismic data is combined with the shot data relating to said shot to obtain aggregated data, the interpretation of which provides a picture of the seabed; said method comprises the following steps: - the second vessel to the first vessel passes through the radio link a series of preliminary estimates shots, said series sequentially updated in time, and each series comprises time points planned for the next N rounds with N≥2; - for each shot activates the second vessel, the at least one seismic source of said preliminary estimates, and transmits the first vessel through said radio line, data relating to said shot - the first with bottom activates the recording system for recording data shot or periodically at last received a series of preliminary rounds estimates or continuously - When analyzing the resulting series of preliminary rounds evaluations, the first vessel finds that it has not received the data relating to at least one execution of shot, the first vessel to the second vessel sends a request and receives in return the missing data shot - for
