GraviProbe 2.0

Rheology version

Fast and light sediment profiling system

The GraviProbe is a free fall impact instrument, characterising the underwater sediment layers during intrusion. Under its own weight it accelerates and penetrates fluid and consolidated sediment layers. The GraveProbe is able to very accurately measure the thickness of the fluid mud and consolidated mud layers, even in gassy environments.

The soil strength conditions of the intruded sediment layers are determining the probe/s dynamically behavior

The data acquired from on-board accelerometers and pressure sensors is feeding a dynamical model which determines the geotechnical parameters of the intruded soil (depth, undrained shear strength (dynamic and static S) and dynamic cone penetration resistance).
