Australian Seabed Mapping Data from Multibeam Sonar Surveys

Australia's offshore jurisdiction, covering over 10 million square kilometers, has been mapped using multibeam swath-mapping systems since the 1960s. The data, aggregated by the Australian Ocean Data Network, includes bathymetry contour maps and acoustic imagery from systems like SeaBeam, GLORIA, and Simrad EM12D. Surveys have been conducted in areas including the Great Barrier Reef, off Tasmania, Bass Strait, and the Macquarie Ridge.

Australian Seafloor Video and Imagery from Geoscience Australia Surveys, 2007 Onwards

From 2007 onwards, Geoscience Australia collected towed video and still images across 21 marine surveys, including Antarctic waters. The data provides direct observations of coastal and deep-sea environments to document seafloor habitats and organisms. Video footage is captured 1-2 metres above the seafloor, covering distances up to 1-2 km and offering real-time viewing from the ship.

Australian Seabed Mapping with Multibeam Sonar Systems

Less than 5% of Australia's offshore jurisdiction has been mapped using seabed swath-mapping technology. The dataset describes historical and modern surveys using systems like SeaBeam, GLORIA, and Simrad EM12D, conducted by institutions including AGSO and the RAN Hydrographic Service. Mapping efforts aim to support geological understanding, resource assessment, and management of Australia's Exclusive Economic Zone.

Shallow Benthic and Geomorphic Habitat Maps for Northern and Western Australia, 2018-2023

High-resolution 10-meter raster maps classify shallow benthic and geomorphic habitats across Northern and Western Australia from 2018 to 2023. The dataset was produced by a consortium including UQ, UNSW, and AIMS using Sentinel-2 imagery and a semi-automated Random Forest classification workflow in Google Earth Engine. It covers areas from the Houtman Abrolhos Islands to Cape York, including offshore and inshore reef systems.

Australia's Seabed Map 2023: 250m Resolution Bathymetry Grid

Australia's marine region from 92°E to 172°E and 8°S to 60°S, including areas around the continent, Tasmania, and several external territories. The map is a 3D picture of the seafloor compiled from 1582 individual surveys using multibeam echosounders, LiDAR, and other sources, representing decades of data collection. It is based on the revised AusBathyTopo 250m 2023 grid and is a significant improvement over the 2009 version.
