Attention:
Please note that operations with the Seismic Equipment can only be operated upon request. Request operations with the Seismic Equipoment to AWI-Geophysics and AWI-Logistics in sufficient time prior to the cruise. Operations of the system require experienced scientific staff on board. The system is not operated by the ship's crew.
Summary
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, structural map of the subsurface can be created. For this
you need a source (Airguns) and receivers (Hydrophone Streamer).

Components
The Marine Seismic System consits of onboard data control and acquisition computers and tape drives for data storage, a hydrophone streamer and an airgun cluster (GI-guns or G-guns) connected via pressure pipes to the compressor container.
