Claude Lorius

Claude Lorius ( born February 25, 1932 in Besançon ) is a French glaciologist.

He was director of the Laboratoire de glaciology Geophysique et de l'environnement in Grenoble from 1983 to 1988 and is currently emeritus research director at the CNRS

He was a participant of more than 22 polar expeditions, mostly in the Antarctic, and participated in the construction of many international research cooperation, especially the Eisbohrprogramm at Vostok Station.

In 1957 he began his research in the Antarctic in the tiny French station in the Antarctic inland ice in the middle of Charcot 2400m. After several other projects in the summer of 1965, he headed the winter camp in the coastal base station in Terre Adélie and began to collect ice cores with experience. Here he fell into the ice trapped in air bubbles. He reported: "When I watched them burst, as a piece of ice melted in a glass of whiskey, I suddenly had the inspiration that these air bubbles represent unique and reliable evidence of the composition of the air. In the following years, we have proved that. "

This research approach has led to many fundamental work Lorius and enormous national and international research programs to trace the Earth's climate over the past millennia by examining ice cores.

Originated the first international project GRIP 1989 ( Greenland Ice Core Project) with a core, of a total of 3027 m in length, and the American project GISP2 ( Greenland Ice Sheet Project) with a core of 3053 m, of which 1.55 m bedrock, only about 105,000 years back, they would be adequate in 2003 at Dome Fuji ice core layers of 350,000 years back, after the set up by Lorius program of drilling at Vostok was established in 1999 with a record 400,000 years.

The 1995 and 2004 have placed in the way completed drilling at Dome Concordia ( Dome C short ), the European project EPICA, 123 ° east longitude and 75 ° 06 ' south latitude gave the science even 900,000 years old ice.
