More than thirty new and, as yet unclassified, species of marine life were discovered during a science expedition to the Amundsen Sea off Pine Island Bay in Antarctica.
The Amundsen Sea is one of the least explored areas of the Southern Ocean. It contains several deep troughs and basins formed during previous ice ages. Some are more than 1,600 metres deep.
In 2008 a team of marine biologists from British Antarctic Survey (BAS) and collaborating institutes took part in a summer research cruise to study the sea-bed fauna in the area.
What surprised the scientists was the extent of the various communities living in the deep troughs. It’s thought they may have taken refuge in them during past periods of glacial expansion.
Lead research author Katrin Linse said: "At least 10% of all the species collected are new to science, and this figure is likely to rise with further genetic identification."
