Abstract

The "Laboratoire de Glaciologie et Geophysique de l'Environnement" has developed since 1968 a thermal drill system, which reached 905 meters in depth during the summer season 1977-78 at Dome C (Antarctica).

In order to reach deeper layers, we had to modify the system for working in a fluid filled hole.

In 1981-82 in Adelie Land two sets of equipment for drilling in a fluid filled hole were tested. The results encouraged us to build a thermal drill with a 4000 m cable and associated winch.

In 1984 the L.G.G.E. has conceived and built a core drill ale to take back 8 meters long ice cores in order to reduce operating time. Its implementation has required the use of composite materials.
