BASE (Basal Access and Subglacial Exploration) Drill

Through iterative discussion between IDP and science community members, it was determined that the subglacial rock coring drills in IDP inventory (see Winkie Drill and ASIG Drill) are not optimal logistically for retrieving cores from under 200 m of ice, which is an important depth for understanding the first two feet of estimated sea level rise from current melting of the Greenland Ice Sheet. The IDP Long Range Science Plan 2022-2032 prioritized acquisition of a drill rig with increased agility and safety for retrieving rock core from beneath 200 m of ice. IDP worked with community scientists and IDP engineers to develop the IDP Science Requirements for the BASE (Basal Access and Subglacial Exploration) Drill. With community enthusiasm and NSF support from both the Arctic and Antarctic sections, IDP was given approval in February 2022 to pursue the purchase of a 200 m rock coring rig. IDP worked closely with vendor Multi-Power Products Ltd. (MPP) as they modified one of their commercial rigs to meet IDP operational, polar and logistics requirements. In February 2024, two IDP engineers visited MPP in Kelowna, BC, Canada, to ensure all requirements and specifications had been met and received some operational training on the rig. The rig was subsequently shipped to IDP in March 2024. In FY 2025, IDP procured all downhole tooling.

Current Status

IDP is working to design and fabricate auxiliary systems and components for drilling through ice, similar to equipment used with the ASIG Drill, such as an electronic pressure relief valve and equipment for processing ice chips and drilling fluid. The system is expected to be ready for issue in late 2027.
