- Ice core samples retrieve grass/pine needles which proves
Greenland glacier formed 'very fast'
- A team of international researchers working on the North
Greenland Ice Core Project recently recovered what appear to be plant remnants
nearly two miles below the surface between the bottom of the glacial ice
and the bedrock.
- The suspected plant material under about 10,400 feet
of ice indicates the Greenland Ice Sheet "formed very fast,"
said NGRIP project leader Dorthe Dahl-Jensen, a professor at the University
of Copenhagen's Niels Bohr Institute.
- "There is a big possibility that this material is
several million years old -- from a time when trees covered Greenland,"
she said. "Several of the pieces look very much like blades of grass
or pine needles," said University of Colorado at Boulder geological
sciences Professor James White, a NGRIP principal investigator.
- "If confirmed, this will be the first organic material
ever recovered from a deep ice-core drilling project," said White,
also a fellow of CU-Boulder's Institute of Arctic and Alpine > Research.
