DRILLING THROUGH THE GREENLAND ICE SHEET.
Abstract
In July 1966 a USA CRREL drilling team succeeded in penetrating the Greenland ice sheet at Camp Century, drilling through 4550 feet of ice and 12 feet of sub-ice material. The objectives of the project were to gain an understanding of the basic flow mechanism of large ice masses and to collect continuous, undisturbed cores for scientific analyses. The two techniques of core drilling used to complete the hole were thermal drilling and electrodrilling. This preliminary report describes the drilling equipment and techniques used at Camp Century from 1963 to the completion of the deep drill hole in 1966. (Author)
