'Lost world' discovered around Antarctic vents
Date:1/3/2012

there."

The team believe that the differences between the groups of animals found around the Antarctic vents and those found around vents elsewhere suggest that the Southern Ocean may act as a barrier to some vent animals. The unique species of the East Scotia Ridge also suggest that, globally, vent ecosystems may be much more diverse, and their interactions more complex, than previously thought.

In April 2011 Professor Rogers was part of an international panel of marine scientists who gathered at Somerville College, Oxford to consider the latest research on the world's oceans. A preliminary report from the panel in June warned that the world's oceans are at risk of entering a phase of extinction of marine species unprecedented in human history.

"These findings are yet more evidence of the precious diversity to be found throughout the world's oceans," said Professor Rogers. "Everywhere we look, whether it is in the sunlit coral reefs of tropical waters or these Antarctic vents shrouded in eternal darkness, we find unique ecosystems that we need to understand and protect."

ROV dives were conducted with the help of the crews of RRS James Cook and RRS James Clark Ross. The discoveries were made as part of a consortium project with partners from the University of Oxford, University of Southampton, University of Bristol, Newcastle University, British Antarctic Survey, National Oceanography Centre, and Woods Hole Oceanographic Institution supported by the UK's Natural Environment Research Council (NERC) and the US National Science Foundation (NSF).
