They are using a high-pressure hose and sterilised water at near boiling point to blast a passage through more than two miles of ice.
The aim is to analyse ice waters isolated for up to 500,000 years.
The team of 12 scientists and engineers is using sterilised water at near boiling point to blast a passage through the ice to waters isolated for up to half a million years.
The process of opening a bore-hole is expected to last five days and will be followed by a rapid sampling operation before the ice refreezes."
