Abstract: Marine geophysical damper system. At least some of the example embodiments are methods of manufacturing a geophysical data product including obtaining geophysical data by a sensor streamer; and recording the geophysical data on a tangible computer-readable medium. The obtaining may include: towing a sensor streamer and a dilt buoy, the dilt buoy coupled to a proximal end of the sensor streamer by a line, the sensor streamer is submerged in a body of water and the dilt buoy is disposed at the surface the body of water; and during the towing measuring movement of the dilt buoy caused by surface wave action; and selectively damping relative movement between the dilt buoy and the sensor streamer, the relative movement caused by the surface wave action, and the selectively damping by a damper associated with the line.
