Mapping the seafloor: How deep can we go?‎

Australia's ocean territory is vast and covers an area more than 1.5 times the nation's landmass. Within these waters is a diversity of resources, marine species and habitats. And they're deep. Excluding Antarctic waters, 70% of Australia's ocean territory is deeper than 1,000 meters (3,281 feet), and nearly 50% is deeper than 3,000 meters (9,843 feet).
