    Abstract: Seabed consolidation is demonstrated with the data from the New England Mud Patch. Mineralogy information, core analysis, and measurements of wave speeds and attenuations are used to invert for model parameters, particularly the static frame bulk modulus, from which consolidation is calculated. Consolidation is quantified using Pride’s consolidation parameter. Although the sediment is a porous material, it is shown that an elastic approximation, which has fewer input parameters and therefore more efficient, may be used. A couple of elastic approximation models are compared. It is shown that consolidation increases monotonically with depth at the New England Mud Patch. [Work supported by ONR, Ocean Acoustics Program]
