Ocean Bottom Seismometer are part of the Marine Seismic Equipment.

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. The operations of the system require experienced scientific staff on board.

Ocean-bottom seismometers (OBS) are used offshore to explore architecture and structure of the earth's crust and mantle, e.g at passive continental margins, subduction zones oder mid-ocean ridges. The registration of earthquakes (seismology) or of artificial sound waves (seismic refraction) yields conclusions about the properties of the subsurface in different depths.
