Underwater Metal Detection
Metal detectors are commonly attributed to treasure hunting rather than to archaeology or to cultural heritage management. However, there are archaeological sites where the systematic use of metal detecting technology has provided with evidence that would not have been discovered by other means or even would have been lost by construction engineering activities or by erosion. UwArc, assigned by cultural heritage management institutions, has used metal detectors in different archaeological environments dating from prehistoric up to modern time periods. UwArc´s most spectacular respective success was the discovery of copper pendants dating back to the 4th millennium BC.
Archaeological-forensic investigation at Grosser Glasowsee Lake, Brandenburg
In 1945, an American bomber aircraft crashed into Grosser Glasowsee, a small lake about 40 km north of Berlin. Two personnel are still missing. Based on historical sources, it is to be assumed that their bodies are still buried in the debris of the crashed plane.
Following up to a first underwater archaeological evaluation in 2018, the Defense POW/MIA Accounting Agency (DPAA) , with its Partnership and Innovation Department and in partnership with UwArc, conducted a systematic survey of the crash site. In cooperation with the Ingenieurbüro Schlimper, Augsburg and Sensys we combined a variety of geomagnetic and hydroacoustic techniques and employed different types of surveying devices. The northern part of the lake, which after a dry summer proved to be dryed out with mud instead of water at the surface, constituted the focus of the investigation.
