Abstract:

Effective marine environmental management requires base maps of biological resources. Remote sensing techniques are one of the most cost-effective methods of resource mapping. Sonar is the optimal method of remote sensing the seabed in turbid, temperate marine waters. Acoustic ground discrimination systems provide a relatively simple, low-cost method of sea bed mapping but are designed to map the physical environmental variables of topography and seabed type. The BioMar project at the University of Newcastle-upon-Tyne has developed methods of analysing acoustic data in conjunction with biological information to produce biological resource maps. These methods utilise geographic information systems (GIS). These methods are described and illustrated with data from two case studies undertaken for the UK Government conservation agencies.
