Abstract
The invention relates to a method for determining ocean current using geophysical data acquisition means which are on board a ship, said ship towing at least one streamer which is equipped with at least one traction sensor and position measuring means. The invention is characterized in that it comprises the following steps, consisting in: collecting the measurements from said traction sensor, collecting the measurements from said position measuring means, repeatedly calculating a current vector that is representative of the real current by repeating the following operations using a given sampling time step: calculating simulated traction and streamer positioning data for numerous simulation input current vectors, comparing the simulated data to real measurements taken by said traction and position measuring means for each simulation input current vector. The invention also relates to a device used to carry out one such method.
