The Badger-Eclipse Drills are modified Eclipse Drills manufactured by Icefield Instruments, Inc. The drill is an electromechanical system capable of collecting 81 mm (3.25-inch) diameter core to depths of approximately 400 meters. The drill system is transportable by small aircraft or helicopter. IDDO has two Badger-Eclipse Drill systems that it regularly deploys and a third Eclipse Drill was transferred from the University of New Hampshire to IDDO in 2010.
In 2013, IDDO increased the capabilities of the Badger-Eclipse drills by designing and fabricating a solar and wind power system for use in operation of the drill. This new power set up was tested prior to the drill's deployment in May 2013 and was subsequently used with great success to drill two 200 m ice cores near Denali National Park in Alaska. This capability will be particularly useful at field sites where environmental impact is of special concern and where use of a generator for drill operation is not desirable or permitted.
In 2014, IDDO, with input from Badger-Eclipse Drill operators, carefully inventoried all Badger-Eclipse Drill equipment, removed aging and out-of-spec parts from circulation, purchased a new cutter head and cutters and engraved components for easy identification, since the two systems, while similar, are not identical. Late in 2014, IDDO purchased a new Mountain Hardwear Space Station tent for use with the Badger-Eclipse Drill systems. The tent will allow drilling operations to continue safely and reliably in inclement weather and has already proven itself very useful in such conditions during a spring 2015 project in Greenland.
