The National Oceans Office undertook in September 2001 an analysis of Bioregionalisation for the Australian South-east Marine Region, an integration of geological, oceanographic and biological data as the basis for bioregionalisation. The biological and physical assessment was intended to contribute to the implementation of ecosystem-based management in the South-east Marine Region by developing a shared understanding of the ecosystem. The assessment had two streams, ecosystem structure and ecosystem function and incorporated the input from these projects among others: - Production of a consistent, high quality bathymetric data grid for the south-east marine region. - Seabed characterisation including geomorphology, acoustic facies and seabed sampling (GA) - Computer sediment modelling (GEOMAT) - Refine Broad Scale Bioregionalisation (Provinces and Biomes) (CSIRO) - Upgrade deepwater nutrient, water properties and ocean current models (CSIRO) - Rapid assembly of ecological fish data (CSIRO Marine Research in collaboration with Australian Museum, Victoria Museum and NSW Fisheries) - Rapid assembly of ecological invertebrate data (Museum Victoria in partnership with Australia Museum and CSIRO Marine Research) - Bioregionalisation analysis for the South-east Marine Region (CSIRO Marine Research and Australian Geological Survey Organisation [GA]) This dataset contains the spatial distribution of the physical and biological components of the Region resulting from bioregionalisation analysis for the South-east Marine Region. Further detail will be available in the report entitled "An Interim, Draft bioregionalisation for the continental slope and deeper waters of the South-East Marine Region of Australia" by A. Butler, P. Harris et al. (draft only available at time of this metadata compilation).
