Australia's Seabed Map 2023: 250m Resolution Bathymetry Grid
Australia's Seabed Map 2023 provides a three-dimensional picture of the seafloor across a vast area from 92°E to 172°E and 8°S to 60°S, including areas adjacent to the Australian continent, Tasmania, and surrounding islands. The map is based on the AusBathyTopo 250m grid, compiled from 1582 individual surveys using multibeam echosounders, LiDAR, and other sources, and incorporates satellite data for coastline definition. This digital dataset, produced by the Australian Ocean Data Network, represents a significant improvement since its last revision in 2009.
