• Marine seismic surveying vessels in operation have reported slowly-varying motions in the depth of their towed recording (streamer) cables. Full-scale measurement data have revealed that minor fluctuations in the course of the seismic vessel are capable of forcing the towed in-sea hardware in longitudinal and transverse directions. Deviations from the specified target depth of towed seismic cables may give rise to uncertainties and errors in geophysical measurements as well as causing coverage problems due to irregular horizontal movements of the cables. Thus, the operational efficiency of this kind of nautical operation may be negatively affected. The interaction between transverse (depth) and longitudinal motions has been argued to take place at the location of the depth-control devices that are mounted along the streamer cables.
