|Title||Review of Subglacial Till and Bedrock Drilling|
Technical Report PRC 12-02, Polar Research Center, Jilin University, China
Drilling to till and bedrock of ice sheets and glaciers offers unique opportunities for examining processes acting at the bed. Four types of subglacial drilling technologies are considered: (1) non-rotary sampling; (2) non-core penetrating; (3) pipe-string rotary drilling; (4) electromechanical cable-suspended drilling. The different bedrock drilling technologies are reviewed and discussed. The procedure of till and bedrock drilling and the geological description of retrieved debris-containing ice and bedrock cores are given.
