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.
 

Agile Sub-Ice Geological (ASIG) Drill

The ASIG Drill is capable of drilling through 700 meters of ice, taking pieces of ice core along the way, and then recovering 5- to 6-meters of bedrock core with a diameter of 39 mm. The ASIG Drill is much less logistically intensive than the Rapid Access Ice Drill (RAID) deep drilling system developmed by the University of Minnesota Duluth. The ASIG Drill is one of two rock coring drills in the IDDO inventory (see also Winkie Drill).

The ASIG Drill's first deployment was to Pirrit Hills, Antarctica, during the 2016-2017 Antarctic season (PI John Stone) and successfully recovered more than 7 meters of ice core and 8 meters of 39-mm diameter rock core at a depth of 150 meters. Nearly 5 meters of ice core was also collected near the ice-bedrock transition, however, the core quality was poor.
