Winch, Deep Logging

2016-2017 Antarctic Field Season Wraps Up

In addition to the two sub-glacial rock drilling projects described above, IDDO successfully supported three projects at or near the South Pole, and one at WAIS Divide, during the 2016-2017 Antarctic field season. South Pole Ice Core (SPICECORE; PI Murat Aydin; I-164-S) operations were completed in just three years at South Pole, with 1751 meters of ice core drilled, one round of borehole logging (PI Ryan Bay; I-194-S) with the Intermediate Depth Logging Winch completed, and all equipment has now been removed from the site. Engineers Jay Johnson and Josh Goetz completed all remaining activities this season, with help from the science team onsite. Also near South Pole Station, drillers Mike Waszkiewicz and Elizabeth Morton completed a number of holes ranging from 5 to 125 meters depth using the IDDO 4-Inch Drill system (PI Michelle Koutnik; I-193-S). In West Antarctica, despite needing to make a last-minute operator change, borehole logging with the Deep Logging Winch was also successfully completed at WAIS Divide (PI Erin Pettit; I-166-M).

New Technology for the Community

Deep Logging Winch
The new IDDO Deep Logging Winch system, capable of logging to depths of 4,000 meters, is completely built, tested, packed, and ready for future field projects. The list of necessary spare parts is created, but the spares will not be purchased until a project utilizing the winch is funded.

"Clow" Deep Logging Winch
During the Second Quarter, the deep logging winch designed, built and operated by Gary Clow was transferred from the U.S. Geological Survey to IDDO. The winch is currently in Antarctica and will be used for the logging of the WAIS Divide deep borehole during the 2014-2015 field season. IDDO anticipates that the logging winch will be returned to Madison, inspected and repaired as necessary prior to use on any future projects.

Equipment Development

Deep Logging Winch
In the first quarter of PY 2014 (Nov-Jan), IDDO completed the building and testing of a new Deep Logging Winch, capable of reaching the depth of 4,000 meters. At the end of the quarter, the logging winch system required only the completion of the shipping container for the logging tower to be ready for shipment to the field.

Equipment Development

Deep Logging Winch
The manufacturer (Markey Machinery Co.) delivered the Deep Logging Winch in early September. IDDO personnel are in the process of completing the design of the winch sled and minor modification to the winch control system. The winch is scheduled for completion in early 2014.

Equipment Development

Deep Logging Winch
The Deep Logging Winch system is currently in production and is scheduled for delivery to IDDO by August 15th by Markey Machinery Co. IDDO designed and placed a purchase order for the winch sled and, working with the winch manufacturer, modified the winch control system.

Equipment Development

Deep Logging Winch:
IDDO finished specifications of the 4000-meter Deep Logging Winch and placed an order with Markey Machinery Company, Seattle, WA. On March 19, IDDO approved the certified drawings of the entire system developed by the manufacturer, and the winch is in the process of being produced.

Deep Logging Winch

Acquisition of a deep logging winch capable of logging boreholes 4000 meters deep is one of the high-priority items identified in the Long Range Science Plan. Through many IDPO discussions with the borehole logging community and with IDDO, a set of science requirements for a deep logging winch have been developed and are available at:

Erin Pettit, Ryan Bay, and Gary Clow will serve as the chief scientists for the deep logging winch development. The corresponding engineering requirements for the winch were developed by IDDO.

Three bids from manufacturers that are willing and capable of building the winch were received by IDDO and a "winner" identified. IDDO has started working with the manufacturer to ensure that the winch will meet the engineering and science requirements.
