An agile drill capable of retrieving cores of approximately 9 ½ inches (241 mm) in diameter. The BID system had a depth capability of 30 m in solid ice in its original design. The drill, developed for the University of California at San Diego, has been repeatedly used with great success to collect samples of "blue ice" on Taylor Glacier each season since its initial deployment during the 2010-11 field season. Modifications to the drill for use in firn were tested successfully in Greenland in 2013. In PY 2014, the system was modified to allow for deep coring 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. The control box was modified as well. This new BID-Deep system, to which it is referred, is theoretically capable of reaching depths to 200 m. The BID-Deep system was first tested in Greenland during the 2014 Arctic field season, reaching a depth of 187 m. The BID-Deep capabilities were further tested in Taylor Valley in Antarctica during the 2014-2015 field season down to a depth of 70 m.
