Engineering team heads to Antarctica to explore hidden lake

ristine environment.

"We are tremendously excited this is a frontier science project with engineering and technology at the forefront. Scientists and engineers from two of the Natural Environment Research Council's (NERC) centres of excellence, working in partnership with scientists from eight UK universities, make up the consortium that will search for life in this extreme environment and discover the secrets locked in the sediments. Every piece of equipment is a bespoke design and they have been built in partnership with several UK businesses."

Dr David Pearce, Science Coordinator at British Antarctic Survey, is part of the team leading the 'search for life' in the lake water. He says:

"Finding life in a lake that could have been isolated from the rest of the biosphere for up to half a million years will tell us so much about the potential origin of and constraints for life on Earth, and may provide clues to the evolution of life on other extraterrestrial environments. If we find nothing this will be even more significant because it will define limits at which life can no longer exist on the planet."

The unique five metre long water sampling probe was designed and built by engineers at the National Oceanography Centre in Southampton. Made of the highest grade of titanium to ensure maximum sterility and strength, it will collect 24 water samples at different lake depths. It will also capture the top layer of sediments at the lake-floor / water interface.

Scientists at British Antarctic Survey and Durham University, working in partnership with Austrian business UWITEC, have designed and built a sediment corer, which can extract a core up to three metres long. The unique percussion-driven piston corer is strong enough to penetrate even the most compacted glacial sediments to extract a core sample.

Next year the team of scientists and engineers will live in tents, spending around three months working at one
