Abstract A seismic apparatus includes one or more seismic cable systems configured to acquire seismic data, each seismic cable system having one or more of a cable jacket, a reservoir for a ballast fluid or other ballast medium, and an actuator or other transfer mechanism configured to transfer the ballast fluid between the reservoir and the seismic cable system during acquisition of the seismic data, e.g., where the ballast fluid is transferred to the seismic cable system within the cable jacket. A controller can be configured to adjust a buoyancy of the seismic cable system responsive to the transfer of the ballast fluid, e.g., where the internal volume expands or contract based on the fluid transfer. La présente invention concerne un appareil sismique comprenant un ou plusieurs systèmes de câble sismique conçus pour acquérir des données sismiques, chaque système de câble sismique comprenant une ou plusieurs d'une gaine de câble, un réservoir pour un fluide de ballast ou un autre agent de ballast, et un actionneur ou un autre mécanisme de transfert conçu pour transférer le fluide de ballast entre le réservoir et le système de câble sismique pendant l'acquisition des données sismiques, par exemple quand le fluide de ballast est transféré vers système de câble sismique à l'intérieur de la gaine de câble. Un dispositif de commande peut être conçu pour ajuster la flottabilité du système de câble sismique en réponse au transfert du fluide de ballast, par exemple quand le volume interne se dilate ou se contracte en fonction du transfert de fluide.
