Successful Support Across Antarctica

Crary Ice Rise Shot Holes (PI Conway)
IDDO supplied PIs Twit Conway and Paul Winberry with a Small Hot Water Drill to create shot holes for their Crary Ice Rise seismic work. All shot holes were successfully drilled by the science team, and the equipment is currently onboard the cargo vessel headed to the U.S.

Beneficial, User-Identified Upgrades Made to IDDO Small Hot Water Drill

Based on excellent feedback from the Principal Investigators (PIs) and science teams who frequently use the IDDO Small Hot Water Drills (SHWD) for seismic work, IDDO worked during the Third Quarter (May 1, 2015 - July 31, 2015) to implement several beneficial upgrades to the system, including new fittings, hose, a new nozzle and added safety features in addition to maintenance of the heaters and power unit. Working closely with engineers and summer students at the UW Physical Sciences Lab (PSL) in Stoughton, WI, IDDO has benefitted from the wealth of hot water drilling knowledge located there, as several of the engineers at PSL participated in the design and operation of the Enhanced Hot Water Drill used for the IceCube project. This synergistic relationship is expected to continue, as IDDO looks toward another tier of upgrades to the SHWD in PY 2016 (November 1, 2015 - October 31, 2016). The system pictured below will be shipped to Antarctica in September and used by PIs Howard Conway and Paul Winberry to create shot holes for seismic work to investigate the grounding line dynamics of the Crary Ice Rise.

IDDO Continues Collaboration with UW PSL Hot Water Drilling Experts to Make User-Identified Upgrades to Small Hot Water Drills

During PY 2014, IDDO worked with hot water drilling colleagues at the University of Wisconsin Physical Sciences Lab (PSL) to develop maintenance and upgrade plans for IDDO's aging Small Hot Water Drill (HWD) systems. The engineers at PSL were heavily involved with the design and operation of the very successful Enhanced Hot Water Drill for the IceCube project as well as the Askaryan Radio Array (ARA) Hot Water Drill for the more recent ARA project at the South Pole Station. Throughout PY 2015 and PY 2016, IDDO plans to work with the PSL engineers to specify and purchase many new components for the IDDO Small HWDs based on user feedback, as almost exclusively the PIs and their science teams operate these drills. During the Second Quarter, IDPO-Dartmouth organized a virtual meeting that enabled scientist-users of the drill an opportunity to see the planned upgrades and provide feedback to IDDO. The upgraded Small HWD, with a depth capability of 0-60 meters, will complement the planned Scalable Hot Water Drill, which is scalable in depth range from 60-1000 meters, depending upon individual project needs. Late in the quarter, assembly and testing of the existing Small HWD equipment was underway and IDDO plans to purchase upgraded components beginning in the Third Quarter.
