Brief description

The auSEABED was created by Dr. Chris Jenkins, a former staff member of School of Geoscience, to describe the materials of the Australian Maritime Region - in all, an area comprising 1/12 of the earth's globe. Because of Australia's relatively small population base and inadequate funding for at-sea science, maximum use of existing data had to be made to achieve a workable mapping. This motivated research into the use of datasets that were diverse in their methods, navigation, technologies, aims, standards, formats - and whether numeric or linguistic. The research resulted in a data mining system designed especially for the seabed.
These web pages describe the digital GIS coverages that are now available for the seabed materials of the Australian maritime areas.

Statement: A variety of instruments were used to collect the more than 275,000 attributed sample sites that comprise auSEABED.
Statement: The distribution - geographic and by attribute - is not uniform, and it is clear from statistics where effort has been concentrated to now, and where major requirements are. Inshore (coastal) zone mapping is the most glaring shortcoming: it is tedious for reasons of the fractal complexity of coastlines, navigation hazards and the need for small-boat operations. Geographically, the most under-mapped regions of shallow depth are the Great Australian Bight, Gulf of Carpentaria and within the complex Great Barrier Reef.

Purpose
A primary goal of auSEABED is to provide inputs of important seabed parameters to the community of ocean modellers, including wave damping, nutrient budgets, sediment erosion, object burial, acoustic propagation and backscatter, stratigraphy and carbon cycle. This is done mostly through grids of seabed properties in areas of concern. As demonstrations of the capabilities, a number of modelling products are illustrated here.
