IDDO Completes Support of 2017-2018 Antarctic Season

IDDO deployed four separate drilling/logging systems for use during the 2017-2018 season, along with three IDDO equipment operators.

IDDO engineer Tanner Kuhl accompanied the 4-Inch Drill and Deep Logging Winch to Minna Bluff for the Rapid Access Ice Drill (RAID) second Antarctic field trial (AFT2; PIs Goodge and Severinghaus; D-551-M) project. The 4-Inch Drill was used successfully to drill one hole to 131 meters, with firn air samples collected by the science team (PI Severinghaus; D-551-M) from nine separate depths. The 4-Inch Drill coring activities found the firn-ice transition at Minna Bluff to be at approximately 82 meters depth, providing valuable firn-ice transition data for the nearby RAID AFT2 operations. IDDO's Deep Logging Winch was deployed to allow for logging of the RAID AFT2 boreholes using Ryan Bay's optical logging tool. The Deep Logging Winch was ultimately not used during the RAID AFT2, however, as the RAID system was unable to complete a hole to depth. While development, fabrication and testing of the RAID system is being conducted by DOSECC Exploration Services LLC and is not an IDPO-IDDO activity, Kuhl's deployment to Minna Bluff also gave him the opportunity to drill with the RAID field team, learn about the RAID system operation, and provide trouble-shooting support to the RAID team.

The Intermediate Depth Logging Winch was sent to the South Pole, where it was used successfully by the Askaryan Radio Array (ARA) field team (PI Karle; A-107-S) to log the existing South Pole Ice Core (SPICEcore) borehole to gather physical properties data as well as radio properties and ARA calibration data. IDDO engineer Chris Gibson joined the ARA field team at the South Pole this season to gain valuable hands-on experience with their hot water drilling operation.

The Winkie Drill successfully completed its second field season, this time in Ong Valley (PIs Putkonen and Morgan; G-192-M). Drill upgrades made in Madison following the previous project in the Ohio Range proved successful, and IDDO engineer Grant Boeckmann was able to collect quality mixed media cores consisting of ice, silt and rock. While the original project goal was to collect three cores from two separate sites (six cores total), the ice encountered contained much more sand, silt and rock than the PIs anticipated. One core was collected at each of the two sites, with one core to 10 meters and one to 12 meters depth. The higher debris content proved very useful for the science goals, reducing the number of holes needed.

IDDO also supported six hand auger projects during the 2017-2018 field season through the provision of Hand Auger and Sidewinder equipment.

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.

Successful Deployment of IDDO's Two New Rock Coring Drills

The Winkie Drill was deployed to the Ohio Range region (PI Sujoy Mukhopadhyay: G-438-M) in late November for its first funded field project. IDDO engineer Grant Boeckmann and the science team drilled a series of shallow boreholes that resulted in the successful collection of five rock core samples and one sample of frozen and largely unconsolidated debris. The Winkie Drill system functioned very well for its first official deployment. Refinements will be made when the equipment returns from Antarctica this spring.

During the quarter, IDDO completed the fabrication, assembly, and modifications of the Winkie Drill. On 9/16/16, the Winkie Drill system was shipped to Port Hueneme, CA, for its first Antarctic deployment on PI Mukhopadhyay's project (see Field Support to Antarctic Projects above).

Winkie Drill System Tested at IDDO Warehouse

During the quarter (May 1 - July 31), IDDO transitioned from the design and fabrication phase of Winkie Drill development to the in-depth system testing phase. Using multiple test set ups and simple testing apparatus assembled by IDDO engineers, full scale system testing was conducted in solid ice, solid granite and in ice ingrained with various sizes of granite chunks. The cutting ability of a number of bits with varying geometries was tested. In late July, IDDO invited Earl Maynard to Madison to assist with the testing. Mr. Maynard has decades of international experience using the Winkie Drill. His participation served as a very beneficial training opportunity for engineer Grant Boeckmann, as he is scheduled to deploy with the drill to the Ohio Range in Antarctica this coming 2016-2017 field season.

During the third quarter, IDDO completed an internal system design review as well as all necessary fabrication, assembly, and modifications of the Winkie Drill. Multi-round system testing was completed, including ice drilling with a newly-designed air chip transport system and modified Forstner and Irwin bits, coring through an ice/rock interface with multiple layers of ice and different sizes of granite rocks using two different types of mixed-media coring bits and a range of Isopar K temperatures, and coring solid granite with three different types of coring bits and two types of drilling fluid (Isopar K and water). System testing was very successful and helped inform selection of drilling/coring bits for a variety of ice/rock conditions the drill may encounter in the field. In conjunction with system testing, IDDO completed two days of operational training, conducted by Earl Maynard, a Winkie Drill expert, in Madison in July 2016. IDDO continued minor system modifications and started final procurement of replacement and spare parts.

Winkie Drill Development in Full Swing

IDDO ramped up its work on the Winkie Drill system during the quarter. Several IDDO engineers were able to test the system's ability to auger through ice outside of McMurdo Station in early February. IDDO also researched and performed additional testing with regard to ice chips transport using a small air compressor. IDDO engineers are working to prepare the system for upcoming Antarctic work in 2016-2017, where a series of holes will be drilled in ice 10-50 meters deep, below which 50 cm bedrock cores will be collected. Utilizing proven rock coring technology in the off-the-shelf rig, along with proven ice coring and ice chips transport technologies, IDDO looks forward to bringing shallow, agile sub-glacial bedrock coring to life.

Winkie Drill
During the Second Quarter, IDDO continued its modifications and upgrades to the off-the-shelf Winkie Drill purchased from Minex. Early in the quarter, IDDO was able to test its adaptations of auger flights during the Rapid Access Ice Drill (RAID) Auger and Packer Test near McMurdo Station. Important information was gained regarding penetration rates, expected fuel consumption, and the augers' ability to transport ice chips to the surface. Taking advantage of the ASIG Drill test set up, the transportation of ice chips by air was tested as a proof of concept for drilling options in the deep field. Later in the quarter, IDDO identified two types of mixed media coring bits, completed fabrication of a rig base for the system to support the drill and evenly distribute loads across the snow surface during core breaks, completed installation and testing of a variable frequency motor drive for the mud pump, and completed modifications of a drill fluid filtration drum. IDDO will continue its work into the Third Quarter, and also plans to complete additional testing and training in Madison in July 2016, prior to shipping the system to Antarctica in September.

Winkie Drill
IDDO received approval from IDPO to pursue purchase of a commercially available Winkie Drill from Minex. Following telecons with IDPO, NSF and Ohio Range project PIs Robert Ackert and Sujoy Mukhopadhyay, IDPO-IDDO determined purchase of this new rock coring drill would better serve the needs of the Ohio Range project to obtain rock samples from the ice-bedrock interface, and the larger community, as opposed to making repairs and modifications to the Koci Drill. The new Winkie Drill is also expected to prove useful for the joint RAID/ASIG auger and packer tests near McMurdo in February 2016. Necessary purchase orders have been submitted. Upon receipt of the rig, IDDO will make modifications to the Winkie Drill to expand its capabilities to include augering and coring through ice.
