Side scan sonar data gathered at the primary scuttling location of the Von der Tann and over an area of seabed to the east and north east of this, identified anomalies connected to the raising of the hull by Cox and Danks on 7 December 1930 and the removal of parts of the superstructure during towing of the hull to shallow water close to the Cava shore. Anomalies were inspected by diver survey.
The following anomalies at the primary scuttling location probably represent loss from the time of the scuttling or blasting activity at the time of the lift of the hull in 1930. All locations are projected in UTM 30 N (WGS84 datum).
