“Konrad Steffen, an Arctic scientist whose work showed that climate change is melting Greenland’s vast ice sheet with increasing speed, died on Saturday in an accident near a research station he created there 30 years ago. He was 68.
Police investigators said he had fallen into a crevasse in the ice and drowned in the deep water below.
A fellow scientist at the station, Jason Box, said the crevasse, or large crack, was a known hazard. But he added that high winds and recent snowfall had made visibility poor and landmarks harder to spot.
The small group at the site — christened Swiss Camp by Dr. Steffen — was installing new equipment when he walked off to perform another task. Over the next few hours, Dr. Box said, they assumed that Dr. Steffen had gone back to his tent for a nap. But when they finished their work he was nowhere to be found.”
