2. Lake Ellsworth In December 2012 a team of British scientists and engineers will embark on one of the most extraordinary and ambitious explorations of our time – to drill in to an ancient Antarctic lake buried beneath through 3 km of solid ice. Lake Ellsworth is one of more than 400 sub-glacial lakes found lying beneath the icy continent and for years scientists have speculated that clues to the Earth’s past climate may be locked in lake sediments and that unique forms of life may have adapted to these extraordinary habitats. The only way to find out is to explore. All images © BAS
