Geophysical surveys will be conducted with the objective of locating the former dry docks, the foundations of buildings associated with the shipyard, and the buried remains of the schooner. Geophysical data will include 3-D ground-penetrating radar (GPR) and magnetometer surveys. GPR will detect and image subsurface objects and is in wide use in archaeology for locating and mapping buried architectural features. Magnetic surveys will be collected over the survey site to map the distribution of ferrous debris and to locate the presence of soil disturbances associated with backfilling of the shipyard basin and dry dock area. These magnetic anomalies will enable us to characterize the extent of man-made ferro-metallic objects and archaeological materials (e.g. pottery, refuse). Within shipyard site, magnetic targets of interest will include hand tools, iron fittings, and ship fasteners. The distribution of magnetic targets will then be mapped to identify the yard’s ‘debris field’, whilst also confirming the location of the schooner hull.
