0Summary
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.

0Components
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. as seismic source.
Parts of airgun deployment rail are stored in container WCAU351219-7.
