SYDNEY - Hundreds of new marine species and previously uncharted undersea mountains and canyons have been discovered in the depths of the Southern Ocean, Australian scientists said Wednesday.
A total of 274 species of fish, ancient corals, molluscs, crustaceans and sponges new to science were found in icy waters up to 3,000 metres (9,800 feet) deep among extinct volcanoes, they said.
The scientists mapped undersea mountains up to 500 metres high and canyons larger than the Grand Canyon for the first time, the government’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) said.
The finds were made in marine reserves 100 nautical miles south of the Australian island of Tasmania during two CSIRO voyages in November 2006 and April 2007 using new sonar and video technology as well as seafloor sampling.
Announcing the discoveries in the Tasmanian capital Hobart, CSIRO scientist Kate Wilson said more was known about the surface of Mars than the depths of the world’s oceans.
“In Australian waters, for example, more than 40 percent of the creatures brought to the surface by our scientists on a voyage of discovery have never been seen before,” she said.
