High-resolution 3D reflection seismic on a tidal flat: acquisition, processing and interpretation

The survey was carried out on the Plaat van Oude Tonge, an intertidal shoal in the Eastern Scheldt inlet. The high resolution reveals internal structures in a dune-like structure which is in contradiction with the general NE-SW trend of the ridges of the Westland Formation. The 3D figures show relief in the flanks of the dune, structures which may have been caused by erosion from surface water run-off.
