The GraviProbe analyzes underwater sediment layers during intrusion. Under its own weight it accelerates and penetrates fluid and consolidated mud layers.
The data acquired from on-board accelerometers, inclinometers and pressure sensors is feeding a dynamical model which determines the geotechnical parameters of the intruded medium.
