New Scientist has posted this remarkable footage of a camera being lowered down a moulin in Greenland, and reveals that Konrad Steffen’s team, moulin explorers extraordinaire, are inventing a new extreme sport:
Later this year, the team will be boldly going where no researchers have gone before. Under the guidance of expert climbers, they plan to descend deep into a moulin in person. They will leave temperature and flow sensors along the way, so they can track how the tunnel changes throughout the year.
Steffen’s team also released hundreds of special rubber ducks into moulins, but none have yet appeared at the edge of the ice sheet. He fears they may have been ground to pieces by the moving ice. More at the Guardian.
