Winkie Drill

Description

In 2015, IDP purchased a commercially-available rock coring Winkie Drill system from Minex. IDP subsequently worked to upgrade the system to add ice augering and ice coring capabilities. The system has a depth capability of 120 meters with AW34 sized drill rods. All components of the Winkie Drill system can fit in a Twin Otter or similar-sized aircraft.

The ice augering capability of the system was initially tested outside of McMurdo Station, Antarctica in February 2016. The system then underwent more comprehensive testing in Madison prior to its shipment back to Antarctica in September 2016 for a funded field project in 2016-2017. The drill performed well during that initial season, drilling 8 holes between 12-54 meters depth. Rock cores between 28-67 cm in length were collected in five of the holes and a semi-consolidated sediment core was retrieved from one hole. Modifications were subsequently made to accommodate a request for larger core diameter as well as the replacement of the gas engine for an electric motor, for improved reliability and to allow for operation within a tent. The drill was again used successfully during the 2017-2018 season in Ong Valley, Antarctica, where two continuous mixed-media cores were collected to a depth of 9.45 meters and 12.36 meters. Drill rod and casing were shipped to Antarctica in September 2018 in advance of a planned project at Thwaites Glacier during the 2019-2020 field season.

This drill is one of two rock coring drills in the IDP inventory (see also ASIG Drill).
