A statement released on behalf of British scientists running the Antarctic mission confirmed drilling was called off in the early hours of Christmas Day:
– British Antarctic Survey
Drilling was proceeding well during the weekend after a replacement part was fitted to the boiler used to heat water for drilling.
Drilling stopped after the team was unable to form properly the water-filled cavity 300 metres beneath the ice.
This cavity was to link the main borehole with a secondary borehole used to recirculate drilling water back to the surface.
