Abstract: 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, an antitorque system and an electronic pressure chamber. The lower part of the IBED comprises an auger core barrel, reamers, a core barrel for ice/debris-ice drilling and a conventional geological single-tube core ba… Show more

“…Visual observations of the walls, roofs and inner auxiliaries indicated that all components were in good condition during and after the transportation. At the test site, 2-week drilling operations resulted in a borehole that reached the bedrock at a depth of 198 m (Talalay and others, 2021).

“…1). The published data of subglacial drilling with final depths >50 m are limited to a 2.2 m-long bedrock core in the coastal area of Queen Mary Land near Mirny Station (Treshnikov, 1960); a short, 10 cm-long bedrock core beneath Taylor Dome (Steig and others, 2000); an ~8 m-long bedrock core near the Pirrit Hills (Kuhl and Gibson, 2019); a short, 6 cm-long bedrock core at the flank of the Dålk Glacier near Chinese Zhongshan Station in the Larsemann Hills (Talalay and others, 2021); and a little over 2 m in length bedrock core at Minna Bluff (Goodge J and Severinghaus J, 2020, ). Bedrock cores have never been obtained from inland East Antarctica.…”

“…An effective data acquisition and drilling process control is the guarantee for the quality of the borehole and core samples. The control system was tested during the 2018–2019 summer season near Zhongshan Station, East Antarctica in a course of drilling to the bedrock at a depth of 198 m. Three related papers describe the general concept of the drilling rig (Talalay and others, 2021 a ), Ice and Bedrock Electromechanical Drill (IBED) (Talalay and others, 2021 b ) and auxiliaries (Fan and others, 2021).…”

“…Drilling operations can be carried out around the clock on a three-shift basis, with two drilling operators working during each shift. Firn–ice–bedrock core drilling is carried out with an ice and bedrock electromechanical drill (IBED) after rigging up the ASDR (Talalay and others, 2021b). A typical sequence of drilling operations is shown in Figure 1.…”
