IDDO maintains and operates existing ice drilling equipment 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, and studying subglacial geology.

In Development

Here you will find equipment that is currently in development, being proposed for development, and/or being proposed for acquisition by the U.S. Ice Drilling Program.

Requesting Field Support

If you are preparing a proposal that includes any kind of ice drilling support from IDPO-IDDO, you must contact IDPO-IDDO
( ) at least six weeks before you submit your proposal to obtain a Letter of Support and a Scope of Work/Cost Estimate, both of which must be included in your proposal.

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 5-6 meters of bedrock core with a diameter of 39 mm. Read more...

Project Schedules

Blue Ice Drill – Deep

The Blue Ice Drill – Deep is based on the original Blue Ice Drill (ice cores of 241 mm (9½-inch) diameter) but with a greater depth capability.

Deep Logging Winch

The Deep Logging Winch is capable of logging boreholes 4000 meters deep and can operate at temperatures as low as -45 degrees C.

Project Schedules

Intermediate Depth Drill (IDD)

The IDD is capable of producing 2-meter long cores 98 mm in diameter to depths of 1,500 meters. The IDD is sufficiently portable that it can be used for coring at a wide variety of sites. Read more...

Project Schedules

Replicate Ice Coring System

The Replicate Ice Coring System collects additional ice at depths of interest by deploying into an existing borehole and then deviating from it.

Winkie Drill

Winkie Drill

An agile commercially-available rock coring unit adapted by IDDO for subglacial rock coring. Using standard AW34 drill rod, the system has a depth capability of 120 meters. Read more...
