Winch Simulator

Equipment Development (2017 Summer)

Winkie Drill
In preparation for the upcoming field season in Antarctica, IDDO outfitted the Winkie Drill with a new electric motor and larger diameter core barrel for collecting 76 mm diameter cores. Testing of the updated drill is ongoing at the IDDO warehouse. The Winkie Drill will be shipped to Antarctica in September where it will be used to collect dirty ice cores in Ong Valley, Antarctica, to depths of up to 20 meters.

Stampfli 2-Inch Drill
IDDO shipped the very lightweight, agile Stampfli 2-Inch Drill system to Greenland for field testing in June in conjunction with a funded field project taking place at Summit Station. The small, solar-powered drill operated well during the field test, producing 58 meters of core. Based on the results of the field test, IDDO is working to make minor repairs and modifications to the drill, procure spare parts, and develop a lightweight packing strategy for this system. The system could be ready for deployment and PI operation as early as the 2017-2018 Antarctic field season.

Rapid Air Movement (RAM) Drill
A conceptual design for extensive weight reduction based on the revised science requirements was completed in July. The conceptual design was presented to community scientists Sridhar Anandakrishnan and Paul Winberry for input in early August. Following that external review and any necessary modifications to the design, IDDO plans to begin purchasing primary components for the lighter-weight RAM Drill system in September/October.

Sediment Laden Lake Ice Drill
The Sediment Laden Lake Ice Drill is a lightweight, field portable hot water drill for drilling through several meters of sediment-laden lake ice. Following the April external design review and the ordering of components in May, IDDO began assembly of the system in June and plans to complete simple functionality testing at the IDDO warehouse in late summer and early fall. The system could be ready for deployment and PI operation as early as the 2018 Arctic field season.

Foro 3000 Drill
The Design Review of the Foro 3000 Drill was held on June 6. The Design Review was a virtual meeting where IDDO presented the Conceptual Design for the drill, and community scientists Eric Steig, Ed Brook, and T.J. Fudge provided feedback from the scientist/user perspective. The Conceptual Design for the drill is now complete. The Foro 3000 Drill is conceptually the same design as the existing Intermediate Depth Drill, but with a depth range extended to 3000 meters and drill run length extended from 2-meters to 3-meters.

DISC Drill versus Foro 3000 Analysis
Per discussions between IDPO, IDDO and community scientists, the next deep U.S. ice coring project will likely target Hercules Dome, Antarctica. IDDO, with assistance from Antarctic Support Contract and IDPO, is currently working with community representatives on a DISC Drill versus Foro 3000 Drill analysis, to help determine which system should be used for drilling at Hercules Dome. The analysis results will be summarized into a report for use by NSF and the science community.

Winch Simulator
Following discussions with Mary Albert and PI Ryan Bay, and due to decreased interest by the science community in IDDO purchasing an off-the-shelf winch simulator unit or designing a custom unit, IDDO plans to design a simple simulator circuit for each logging winch in inventory. IDDO envisions providing these circuit designs to PIs for building at their own institutions. PIs could then perform limited pre-deployment testing on their logging tools; however, IDDO will still encourage PIs to travel to Madison to test logging tools on the actual winches to be deployed. IDDO plans to complete design of the simulator circuits by the end of October.

Requesting Field Support

If you are preparing a NSF proposal that includes any kind of support from IDP, you must include a Letter of Support from IDP in the proposal. Researchers are asked to provide IDP with a detailed support request three weeks prior to the date the Letter of Support is required. Early submissions are strongly encouraged.

Program Information

The U.S. Ice Drilling Program (IDP) is a NSF-funded facility. IDP conducts integrated planning for the ice drilling science and technology communities, and provides drilling technology and operational support that enables the community to advance the frontiers of climate and environmental science.
