Geomorphology of the Australian Margin and Adjacent Seafloor

This data set provides outlines for the maximum spatial extent of seabed geomorphic units for Australia's Exclusive Economic Zone, including the offshore island territories, but excluding Australian Antarctic Territory. Twenty-one geomorphic feature types were identified and mapped, following definitions published by the International Hydrographic Office (IHO, 2001).

Value: The geomorphology of the seabed is used to constrained surface geology of the sea floor, important in resource exploration, marine zone management and for understanding the physical environment

Scope: The area covered includes the seafloor within the Australian marine jurisdiction surrounding the Australian mainland and island territories of Christmas, Cocos (Keeling), Macquarie, and Norfolk Islands (Heap & Harris 2008).
