Abstract
Chirp sub-bottom profiler (SBP) provides the high-resolution seismic sections with a decimeter scale vertical resolution and are used in various geophysical and geological studies. We conducted a pseudo 3D Chirp SBP survey to produce a 3D Chirp SBP seismic volume for an ancient wooden shipwreck in Mado, Taean Peninsula, Korea. The survey lines were designed to cross the shipwreck at 2-m intervals in the 30 × 250-m survey area. To improve the quality of Chirp SBP data, we used a newly constructed recording system that could record the raw data. An optimal processing sequence divided in 2D and 3D data processing was specifically designed to create a 3D Chirp SBP volume from a pseudo 3D Chirp SBP dataset. The final 3D Chirp SBP volume shows the amplitude variation of the shipwreck traces.
