A sheet of ice two miles deep covers the South Pole. Radar evidence suggests there may be LAKES under the ice! In those lakes could be microbes-life forms new to science. Sridhar Anandakrishnan is a Penn State geoscientist. This December, he was in Antarctica, trying to confirm the presence of sub-glacial lakes. His team drilled holes in the ice and set off small explosive charges. The idea was that water would reflect sound differently from earth or bedrock. Dr. Anandakrishnan brought back this audio diary from the field.
