<p>A method for controlling a delay of an air-gun in an aquatic seismic source. Includes a step of receiving an attribute 420 of the air-gun during the aquatic seismic survey; a step of calculating 430, based on a time-delay algorithm that uses the attribute, the asynchronization time of the air-gun; a step of determining 440 whether the asynchronization time is smaller than a given time threshold; a step of instructing a controller to (1) wait 450 for a predetermined time before calculating again the asynchronization time of the air-gun if the asynchronization time is smaller than the given time threshold, or (2) calculate 460 an updated asynchronization time for the air-gun based on the attribute if the asynchronization time is larger than the given time threshold; and a step of sending the updated asynchronization time to a gun controller of the air-gun for adjusting a delay time for firing the air-gun.</p> |
