The sediment sampler was hammered into the ground under the ice in order to recover sediment samples. It is here filled with a mixture of mud and ice.
People are pulling and pushing to guide the 3 ton winch up through the narrow passage to the surface from 8 meters depth. In the other end, the camp bulldozer is pulling hard.
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.
Researchers from the project, known as NGRIP, said particles found in clumps of reddish material recovered from the frozen, muddy ice in late July look like pine needles, bark or blades of grass. Thought to date to several million years ago before the last ice age during the Pleistocene epoch smothered Greenland, the material will be analyzed in several laboratories, said researchers.
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.

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
