Concurrent Session 4: S15: Great Australian Bight – seeking whole-of-system understanding


Chair: Jason Tanner
The Great Australian Bight (GAB) is part of the world’s longest southern facing coastline. Its unusually broad continental shelf also supports the world’s largest temperate carbonate production system and has high levels of benthic biodiversity and endemism. Previous marine research in the GAB was concentrated in coastal waters and more recently on the continental shelf. The deep water assemblages and ecosystems of the GAB are poorly understood. Commonwealth and State governments, existing commercial users and a diverse range of academic, community and environmental groups have identified the need to develop a better understanding of the region’s environmental values, regulatory needs and development potential of the GAB. A complex array of ecological, economic and social issues needs to be addressed to optimize management of future activities. This symposium will include results from a large, integrated study of the ecological processes and socio-economic importance of the GAB that is being conducted through a collaborative research partnership involving two research agencies (CSIRO, South Australian Research and Development Institute), two universities (University of Adelaide, Flinders University of South Australia) and BP Australia.
