Modelling of Pliocene–Pleistocene abyssal mudwaves using synthetic seismograms
The geological significance of seismic reflectors within Pliocene–Pleistocene mudwaves at DSDP Site 603 has been examined using synthetic seismograms. The seismograms generated from physical properties in Hole 603C show good agreement with field seismic profiles. The travel-time to depth conversion permits accurate location of the reflectors in the borehole. Impedance contrasts in the Late Pliocene to Early Pleistocene part of the section are controlled predominantly by density which are related to mean grain size variations. Grain size is inferred to have been controlled by fluctuations in the velocity of the Deep Western Boundary Undercurrent.
