The marine survey program has been completed, revealing 3D images of treasures on the seabed around Southeastern Tasmania and the Macquarie Ridge, midway between Antarctica and New Zealand.
The seabed surveys use a multi-beam swath mapping technique and provide baseline data to support the development of a Regional Marine Plan for the south-east marine Region. The images of deep canyons (5 km in places) and flat topped seamounts just below the surface, mark out the region south of Macquarie Island as a spectacular Australia's marine environment.
The three week research cruise, undertaken by the Australian Geological Survey Organisation in cooperation with the National Oceans Office, surveyed an area more than 140 000 km2.
