Sound Metrics Aids Identification and Classification of Unexploded Ordnance in North Sea

The coast of the North Sea is particularly turbid due to strong currents and large amounts of sediment swept into the seabed by neighboring rivers. As a result, optical cameras are often ineffective, and other imaging sonars lack clear, sharp detail.

To overcome this challenge, Sound Metrics, manufacturer of high-resolution acoustic imaging sonars, supplied an ARIS Explorer 3000 to aid an organization in the identification and classification of Unexploded Ordnance (UXO’s) off the coast of the North Sea with outstanding results.

Due to the clarity provided by the ARIS Explorer 3000 in zero-visibility waters, the sonar provided the organization with the needed detail critical to the accurate identification of UXO. With the ARIS’ high-resolution imaging, the team successfully gathered information on the target’s dimensions, characteristics, and location.

Characteristics of the target were found to be consistent with a highly explosive German LMB Ground Mine – featuring a rounded nose and “oyster-like” tail-shape. Using the ARIScope software measurement tool, the mine was measured to be approximately 2.3 meters in length. Due to the successful identification of the target, the team could effectually evaluate risk and carry out a plan of action to protect seafarers in accordance to industry practice and protocol.
