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...

Project HALO 2022 sails on RV Investigator

Project HALO 2022 has started with Australia's Marine National Facility RV Investigator sailing to the northern Great Barrier Reef with an international science team, to study Halimeda (calcareous green algae) sediment mounds - the largest such bioherms in the world....

Bass Strait bathymetry compilation

Bass Strait bathymetry compilation

The 'Bass Strait Bathymetry 2022 30m' grid has been released on the AusSeabed Marine Data Portal as a bathymetry compilation of available source data. Many thanks to Geoscience Australia, the Australian Hydrographic Office, CSIRO's Marine National Facility and Deakin...

High-tech seafloor mapping is finding surprising structures everywhere

High-tech seafloor mapping is finding surprising structures everywhere

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...

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...
