Scientists claim to have discovered a new underwater world off the Tasmanian coast made up of volcanic mountain peaks that tower about 3km from the seafloor.
During a 25-day research expedition, a team of researchers from the Australia National University detected the chain of volcanic seamounts 400km east of Tasmania using detailed seafloor mapping technology.
A seamount is a mountain that rises from the ocean floor but remains below the water surface.
Mapping revealed seamounts measuring up to 3km (1.9miles) from the seabed, but 2km (1.2miles) below the surface.
