Antarctic Lake Vostok
'might have fish'
here could be some complex animals living in Lake Vostok,
which lies close to 4km below Antarctica's ice sheet.The possibility is raised
by scientists who have sifted genetic material in ice drilled from close to
Vostok's surface.They found signatures for organisms such as bacteria that are
often associated with marine molluscs, crustaceans and even fish.But the team cautions in the PLoS One
journal that this material may also represent past contamination.Scientists
now recognise that Antarctica is underlain by a complex network of rivers, and
many of the identified organisms, or their traces, could perhaps have been
delivered to Vostok from the ocean. The lake is 200m below sea level.It is,
nonetheless, another fascinating twist in the story of this deeply buried lake.
