Airguns Cluster Reflection Seismic is 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-Logistics in sufficient time prior to the cruise. The operations of the system require experienced scientific staff on board.

Airguns Cluster Reflection Seismic is used primarily to generate signals in marine seismics. Depending on the target to be resolved those airguns are towed behind the vessel either as one airgun or several in a cluster or tuned array. Umbilical cords supply the airguns with pressurised air, which is released by a trigger pulse in specific intervals. This then generates the seismic wave. In marine reflection seismology energy and traveltime of the waves are recorded with socalled with hydrophones in a towed streamer.

Airguns have different chamber sizes, which are chosen in relation to the objectives, i.e. target size and depth. The Reflection Seismic Airguns Cluster consits of usually 4 GI-guns with a volume of 2.4 l each, cluster bars as distance pieces and mounting gear.
