Marine seismic data acquisition (seismics) is a technique to generate and record seismic waves in the subsurface. By determining location and shape of seismic reflections below the seafloor, a structural map of the subsurface can be created. For this
you need a source for the seismic signal (Airguns) and receivers for recording the reflected (Hydrophone Streamer) or refracted (Ocean Bottom Seismometer) signals. |

The Marine Seismic System consits of onboard data control and acquisition computers and tape drives for data storage, a hydrophone streamer and/Hydrophone Streamer (reflection seismic) or Ocean Bottom Seismometer (OBS; refraction seismic) and an airgun cluster (GI-guns or G-guns) connected via pressure pipes to the compressor container. |
