Exploration & Discovery of Australia’s Oceans
Deepreef Explorer is the website for Dr Robin Beaman and the scientists working to reveal the underwater landscape and seabed habitats of Australia’s regional seas, from the warm tropical Great Barrier Reef and Coral Sea, to the icy polar waters of Antarctica.
Showcases the latest ocean mapping research and discoveries.
The calcareous green alga Halimeda is a major contributor to inter-reef carbonate sediments and is found along the northern Great Barrier Reef shelf as extensive build-ups of sediment, called bioherms. Halimeda algae meadow (credit Emma Kennedy)These Halimeda bioherms...
Crowdsourced bathymetry is the collection of depth measurements from vessels using standard navigation instruments. Many vessels on the Great Barrier Reef - from dive boats to fishing boats - use some type of echo sounder to measure the depth of water. Combined with...
Submarine canyons are among the largest undersea landscape features on Earth, and act as pathways for most of the terrigenous and carbonate sediment transported from the continents to the deep-sea. Canyons are typically associated with large submarine fans and gravity...
Recent ocean mapping events within Australia’s marine region.
The August 2022 issue of Scientific American magazine features the newly discovered 500 m tall coral reef from the Great Barrier Reef in 'High-tech seafloor mapping is finding surprising structures everywhere' Thanks to Mark Fischetti (Scientific American), Maciej...
One of the world’s largest research vessels, Germany’s RV Sonne, has completed a month-long marine science expedition (SO292) to the Queensland Plateau conducting multibeam surveying, sub-bottom profiling and underwater camera transects around these giant coral...
When does singlebeam echo sounder data start looking like multibeam data? In this 3D view of the seafloor at North Keppel Island, Great Barrier Reef, dense lines of crowdsourced bathymetry data reveal ~2.5 m high underwater dunes (profile is 1 km long). Thanks to the...

This dataset provides the new high-resolution bathymetry model for the Northern Australia, called the nthaus100 grid. The 100 metre-resolution gridded bathymetry dataset covers an area of about 1,442,000 km2, from Broome in Western Australia to Arnhem Land in the...
This dataset provides the high-resolution bathymetry model for the Kerguelen Plateau and south-west Indian Ocean, called kerg_dem (short for Kergulen digital elevation model). The 100 metre-resolution gridded bathymetry dataset covers an area of about 736,000 km2,...
This dataset provides the high-resolution bathymetry model for the Terre Adelie and George V continental margin, East Antarctica, called GVdem (short for George V digital elevation model). The 100 metre-resolution gridded bathymetry dataset covers an area of about...
