Claude Lorius
Claude Lorius (born February 25, 1932 in Besançon ) is a French glaciologist .
Life
From 1983 to 1988, Claude Lorius was director of the Laboratoire de glaciologie et geophysique de l'environnement ( Laboratory for Glaciology and Environmental Geophysics ) in Grenoble , France , and is currently the emeritus research director of the French Center national de la recherche scientifique (CNRS, National Center for Scientific Research ).
He was a participant in more than 22 polar expeditions , mostly to the Antarctic, and was involved in setting up many international research collaborations, especially the ice drilling program at the Vostok station .
In 1957 he began his research in the tiny French station Charcot in the middle of the Antarctic inland ice at an altitude of 2,400 m. After several other projects in the summer, in 1965 he managed the winter camp at the coastal base station at Terre Adélie and began to gain experience with ice cores. He noticed air bubbles trapped in the ice. He said: “When I watched them burst when a piece of ice melted in a glass of whiskey, I suddenly had the inspiration that these air bubbles were unique and reliable testimonies to the composition of the air. We have proven that in the following years. "
This research approach led to much fundamental work by Lorius and huge national and international research programs to trace the earth's climate over the last millennia by examining ice cores.
The first international Greenland Ice Core Project (GRIP) in 1989 with a drill core totaling 3,027 m in length and the American Greenland Ice Sheet Project (GISP) II with a drill core of 3,053 m (1.55 m of which was rock bedrock) only lasted about 105,000 years Back in 2003, the layers of the ice core at Dome Fuji stretched back 350,000 years after the drilling program set up by Lorius in 1999 at Vostok set a record of 400,000 years.
The drilling site of the Dome Concordia station ( Dome C ) of the European EPICA project, which was launched in 1995 and completed in 2004, even provided science with ice that was 900,000 years old.
Since 1989 he has been a full member of the Academia Europaea . In 1994 he was admitted to the Russian Academy of Sciences as a foreign member .
