摘要：
A laser stripe seabed profiler that can be positioned and operated by SCUBA divers is developed. The system is shown to be accurate to within 0.5 mm. A number of examples are presented which demonstrate how the physical impact of towed gear components on a range of sediment types can be measured. These examples also highlight the need to consider the impacts of fishing gears at the level of the gear component. Crown Copyright (C) 2009 Published by Elsevier B.V. All rights reserved.
