Site Event/Activity record EHG1617 - Ground penetrating radar survey - Brora Back Beach, Clyne, Sutherland

A ground penetrating radar (GPR) survey was carried out by CFA Archaeology in 2005 as part of a community archaeology project with Clyne Heritage Society, NOSAS and Shorewatch. The survey was conducted over the sand dune complex and an area around the Saltman's house at Brora Back beach, Clyne. The survey was carried out using a GSSI SIR-3000 central unit and 270 MHz ground coupled antenna. The system was carried and the antenna dragged by foot over the site. A tread was used to measure the lengths and synchronise scans. The first area of investigation was on the dune close to the sea. Two lines were measured along the coastal path and a grid of several GPR lines was measured on top of a dune. Three lines were measured across the area of the Saltman's House. The preliminary results appeared to correspond with what could be seen on the surface and what was already known from other techniques such as augering. <1>
