The natural world is structured hierarchically, and processes within natural regions operate  across a number of spatial and temporal scales (Turner  et al., 2001). Managing marine  ecosystems requires that natural regions be identified and mapped over a range of  hierarchically nested scales, and management  of resources across multiple spatial scales  requires a classification system. The development of classification schemes is an active area of marine research. The EUNIS (European Nature Information System) classification scheme is being developed and managed by the European Topic Centre of Nature Protection and  Biodiversity (ETC/NPB in Paris) for the European Environment Agency (EEA) and the  European Environmental Information Observation Network (EIONET; Davies and Moss,  1999). Alternatively, top–down habitat classification schemes have been developed for global applications in the management of marine resources (e.g. Greene et al., 1999; Valentine et al., 2005). The further development and application of these classification schemes require  explicit information that characterizes marine habitats on a variety of spatial scales. Acoustics is increasingly regarded as the remote-sensing tool that will provide the basis for classifying  and mapping ocean resources. Existing acoustic systems can measure seabed sediment  properties and bedform morphology from scales of centimetres to kilometres.
