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.
 

Prairie Dog

A modification of the hand auger, the Prairie Dog includes a stationary outer barrel that allows operations in solid ice as well as firn. The depth limit is approximately 40 meters (with a Sidewinder). The system is commonly used in warm ice conditions where the two-barrel design aides in chip transport during coring. The system was most recently used in both Wyoming and Montana in 2013, and again in Wyoming in 2016, for ice patch coring.
