The Blue Ice Drill (BID) is an agile drill capable of retrieving cores of approximately 241 mm (9½-inch) in diameter. The BID system had a depth capability of 30 meters in solid ice in its original design and has been used successfully in both Greenland and Antarctica for many years. In PY 2014, the system was modified to allow for deeper coring to 200 m depth at the request of the scientific community. A new cable winch and tower were implemented in the design as well as several new down-hole components. Depth capability is still largely influenced by site/ice characteristics. The standard BID typically utilizes a ropes setup for coring to shallow depths, and the cable winch is used for achieving greater depths. In 2016, IDP initiated fabrication of a second BID-Deep system (BID-Deep 2), based on user demand, and as outlined in the U.S. Ice Drilling Program Long Range Science Plan. Fabrication was temporarily suspended in late 2017 due to budget constraints and decisions on the funding of field projects.
Collecting good core quality at greater depths in attempts to extend the BID’s depth capability has proven challenging. The drill can easily drill through at least 80 m of firn, and deeper through another 70 m of solid ice. The drill has only reached 187 m in practice in Greenland. Site-specific ice properties such as temperature and structure as well as the large core diameter and/or mechanical aspects of the drill are all potential factors that may impact core quality. After prolonged use, many original components are aging and require replacement or redesign. The science community noted in the Long Range Science Plan a desire to pursue component redesign to achieve better core quality down to at least 160 m.

* The depth capability of the BID-Deep is largely influenced by site/ice characteristics. The current equipment is likely reaching its operational limits and assuring acceptable core quality at depths of 200 m would require a re-design of the system.
