During the past two world wars the Thames and surrounds was mined and bombed by all parties and the legacy of these conflicts is the continued presence of unexploded ordnance (UXO). The potential for such material to be present during the development of the site must be considered and appropriate mitigation undertaken to reduce any risk. This report evaluates the manipulation of existing data to establish its potential use in the detection of the likely presence of unexploded ordnance.

Magnetic data cannot be used as a stand-alone tool in the identification of UXO and should be supported with by other remote methods such as side scan sonar. Without further ground truthing or access to a complimentary datasets (such as side scan sonar records) additional features identified only indicate the presence of a ferric object that may or may not be UXO.
