Description

In 1999 a side-scan sonar and proton-magnetometer survey was undertaken in association with the School of Ocean Sciences, University of Wales, Bangor. This used a dual-high-frequency two-fish (100 and 325 kHz), providing a 10 degree transducer beam for maximum range and optimum operational capacity in the expected water depths. Differential GPS enabled positioning accurage to +/- 10 metres. The sonar survey recorded large areas of Scallastle and Ardtornish Bays, as well as the Duart Point wreck and four others. During the same year the Archaeological Diving Unit, based at the University of St Andrews, carried out field trials on new side-scan equipment on two wrecks including the John Preston. <1>
