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.

Halimeda bioherms on the Great Barrier Reef

Halimeda bioherms on the Great Barrier Reef

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 on the Great Barrier Reef

Crowdsourced bathymetry on the Great Barrier Reef

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 of north-eastern Australia

Submarine canyons of north-eastern Australia

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...

Collaboration with Caladan Oceanic in the Coral Sea

Collaboration with Caladan Oceanic in the Coral Sea

Fantastic to be collaborating with Caladan Oceanic to acquire new Kongsberg EM124 multibeam map data in the Coral Sea Marine Park during the ‘Ring of Fire Expedition Part II - South Pacific Trenches’ with the DSSV Pressure Drop and submersible Limiting Factor. DSV...

Crowdsourced bathymetry data improves 3D depth models

Crowdsourced bathymetry data improves 3D depth models

Crowdsourced bathymetry (CSB) data improve 3D depth models for Australia's Great Barrier Reef. Before and after 3D depth modelHere, fishing vessel MV Sharp Shooter's CSB data reveals the deeper channel between shallow reefs previously surveyed with airborne LiDAR...

New 3D depth model of Great Barrier Reef and Coral Sea

New 3D depth model of Great Barrier Reef and Coral Sea

A new 3D bathymetry (depth) model of the Great Barrier Reef and Coral Sea at ~100 m resolution, called ‘gbr100’, is now available at the gbr100 download page. New 3D depth model for the GBRThis revised 3D depth model (V6 – 10 Nov 2020) is a significant improvement on...

Northern Australia bathymetry

Northern Australia bathymetry

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...

Kerguelen Plateau bathymetry

Kerguelen Plateau bathymetry

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,...

Terre Adelie & George V margin

Terre Adelie & George V margin

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...
