Novel sparker

摘要

UK-based Applied Acoustic Engineering has announced the launch of its new Deep Tow sparker. Called the DTS-500, the fish is towed close to the seabed when it emits a high-energy electrical sound pulse, and so overcomes many of the disadvantages of a surface-towed system, especially when operating in deeper water. "One historical problem with a surface-towed system is that the signal deteriorates as it passes through the water column," said Applied Acoustics' technical manager, Neil MacDonald. "Together with interference from sea surface and vessel noise, the quality of the data can be compromised, so we've developed an entirely novel design."
