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. |
