Marine Geophysics

Vibrocorer
This machine allows the extraction of whole sediment columns, up to six metres long, from the seabed by hammering a tube with mechanic vibration into the sea bottom.

Geopulse
This system is perfect for very precise geological prospecting with deep penetration. It consists of an acoustic emitter and a reception matrix. The signal is emitted, reflected along the different seabed layers and captured by the matrix. Once we know the speed of sound propagation and the time it takes the signal to reach the receptors, geophysical profiles of the seabed can be created. This system is located on a little trawler, towed by Aemon.
