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.
 

Sediment Laden Lake Ice Drill

The new Sediment Laden Lake Ice Drill (SLLID) designed and built by IDDO is a 28kW hot water drill useful for creating holes with very little initial water, for freeing instrument cables from the ice, and for accessing equipment deployed beneath the ice. The drill is effective at drilling through sediment laden ice and allows safe servicing of science instruments deployed in the lakes and ocean.

The SLLID is designed to achieve a drilling speed of less than 30 minutes for a 5-inch hole through a 6 meter ice cover. Drill components are small, lightweight and are able to be lifted by a maximum of two people. The drill has stand-alone capability for operation at small field camps at remote sites with no heavy equipment and is intended to be PI/science team operable. Components that allow for clean access drilling were also incorporated in the design.
