Beloved U.S.-Swiss climate scientist and glaciologist Konrad “Koni” Steffen died Saturday while doing research in Greenland. He was 68.
Steffen fell into a deep crevasse full of water, Swiss media reports say, after snow and ice gave way beneath him while he worked near a weather station. Rescue attempts were unsuccessful, and his body was not found.
Jason Box, an ice climatologist at the Geological Survey of Denmark and Greenland who was with Steffen before he died, said he believed his friend “remains 8 meters down in the water,” according to CBS News.
“Personally, Koni was like a father,” Box told CBS. “Immense man. Immense loss. Tears falling around the world.”
