Antarctic subglacial drilling rig: Part II. Ice and Bedrock Electromechanical Drill (IBED)
A new, modified version of the cable-suspended Ice and Bedrock Electromechanical Drill (IBED) was designed for drilling in firn, ice, debris-rich ice and rock. The upper part of the drill is almost the same for all drill variants and comprises four sections: cable termination, a slip-ring section, a...
