Equipment

IDDO maintains and operates existing drills and borehole logging winches, and develops new systems with two principal foci:

  1. to provide high quality ice cores, and
  2. to produce boreholes that provide access to the interior and beds of ice sheets and glaciers for such purposes as embedding instruments, collecting gas samples, setting seismic charges, studying subglacial processes, studying subglacial geology, collecting subglacial bedrock core, and borehole logging.
 

Badger-Eclipse Drill

The Badger-Eclipse Drills are modified Eclipse Drills manufactured by Icefield Instruments, Inc. The drill is an electromechanical system capable of collecting 81 mm (3.2-inch) diameter core to depths of approximately 300 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 capability has proven 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. Late in 2014, IDDO purchased a new Mountain Hardwear Space Station tent for use with the Badger-Eclipse Drill systems. A second identical tent was purchased in June 2016. The tents have allowed drilling operations to continue safely and reliably during inclement weather on recent projects in both Greenland and Antarctica, where drilling progress would have been halted had the tents not been available. In 2015, IDDO initiated redesign of the aging control boxes and readout boxes to provide for simplified operation, weight reduction and new sealed cases. Fabrication of the new boxes was completed in spring 2017.
