Marine Geophysics is currently playing a major role in the investigation, monitoring and management of underwater archaeological sites. At NOCS we have been at the forefront of using acoustic sources to image and characterize archaeology both on the seabed (side scan sonar and swath bathymetry) and the sub-surface (chirp [2D & 3D] and boomer). In particular the group has produced the first pseudo-3D and true-3D detailed reconstructions of buried and partially buried shipwrecks purely using acoustics. Acoustic characterization of archaeological materials is crucial to this work and we are the first group to successfully undertake laboratory experiments to determine the acoustic and physical properties of archaeological wood in various states of degradation. This work not only provides vital data to enhance our seismic interpretations but also for laboratory based conservators that which to non-destructively test fragile wooden objects. Our work has focused not just on shipwreck sites but also on the reconstruction of submerged Late Quaternary landscapes, which are crucial to our understanding of earlier pre-history.
In addition to this geophysical work we are also undertaking fundamental work into the sedimentary dynamics of submerged archaeological sites. This has involved field and laboratory based experiments to investigate both fluid flow and sediment movement around submerged 3D objects (shipwrecks). This work has not only provided essential information for the management of historic sites but is also applicable to a whole range of engineering issues of building in the oceans.
Much of this work is undertaken in conjunction with researchers from other parts of the University of Southampton including: The Centre of Maritime Archaeology; Institute Sound & Vibration Research; School of Engineering Sciences.
