Abstract
Recent advances in field hardware have meant that it has become possible to measurein situ shear wave velocity in the upper few decimetres of sea floor sediment in a routine manner. It is known that shear wave velocity can be primarily related to overburden depth and void ratio. Field-derived empirical relationships have previously been formulated so that it is now feasible to assess the suitability of shear wave data as a means of predicting in situ void ratio. Field measurements perfarmed on the northern Californian shelf are presented which reveal good agreement between predicted and control data.
