Bathymetry of the Australian Antarctic Region 2012

Mapping the seabed in the Australian Antarctic Territory (AAT) reveals the dramatic nature of this seafloor environment which ranges in depth to over 6000 metres in places and is intersected by features such as vast plateaus, volcanic knolls, submarine canyons and rugged coastal channels.

The Bathymetry of the Australian Antarctic Region Flythrough was produced from data collected as part of Geoscience Australia's Antarctic Geoscience Project, and forms a fundamental dataset which is being used to better protect the range of seabed communities within the AAT.

Better insight into the nature of seabed habitats present in the AAT can be achieved by understanding the processes which shape this environment and the diversity of features present. Seamounts for example often host endemic assemblages of species which may not occur elsewhere, while canyons also can support a high diversity of species. By mapping the occurrence of seabed features within the AAT we are better able to define and protect the full range of communities, which inhabit the seafloor.

The Bathymetry of the Australian Antarctic Region Flythrough also takes us through canyons supporting a diverse and fragile seabed community off George V Land, which was declared a Vulnerable Marine Ecosystem in 2008.
