The second quarter (February 1, 2014 - April 30, 2014) saw several Antarctic projects closed out, with final End-of-Season Reports submitted for the Blue Ice Drill's work on Taylor Glacier and for a successful first deployment of IDDO's new Intermediate Depth Logging Winch at Siple Dome. Later in the quarter, IDDO also worked hard to compile and review information for three Support Information Packages for the following 2014-2015 Antarctic field season.
Substantial efforts during the second quarter brought the final setup of IDDO's new Intermediate Depth Drill (IDD) to life. The majority of the equipment was shipped to Scotia, NY by the end of March, with certain critical components shipped shortly after. A team of six drillers completed the PQ process, and all travel arrangements for their deployment were made. The drillers deployed to Scotia on April 21, but were returned home on April 24, due to a mechanical issue with the LC-130 Hercules fleet. IDDO worked with the NSF, CH2M HILL Polar Field Services and the 109th Air National Guard to weigh options for an abbreviated test season and on April 30, the last day of the quarter, IDDO received a call that the northbound Greenland flights were back on. The IDDO crew made it to Summit, Greenland, on May 6 and had the first core drilled at the Isi test site on May 14. The testing of the Intermediate Depth Drill (in Greenland) is now finished. The last core was drilled on Saturday, May 31. The final depth of the test borehole is 285.3 meters. The drillers are now working on packing to prepare the first round of cargo for a flight to Kangerlussuaq on June 4. The remainder of the cargo is scheduled to fly to Kangerlussuaq on the June 10 flight. The drill team was able to complete all desired tests except for the brittle ice drilling test, due to the Hercules issue delaying the start of the field season.
IDDO continued monthly teleconferences with ASC and the SPICEcore PIs in preparation for the IDD's deployment to the South Pole in November 2014. In addition, engineer/ driller Tanner Kuhl attended the 2014 SPICE Core Planning Meeting at the University of California-Irvine.
IDDO worked with NSF, ASC and the dedicated cargo personnel in Scotia, NY to expedite the return of the Blue Ice Drill (BID) system to Madison after vessel-loading issues in McMurdo threatened to delay the return of much of the Antarctic cargo. The BID was needed in Madison in order for IDDO to implement new BID-Deep components and turn the system around for the upcoming Arctic field season. By the end of April, all cargo was packed for PI Vas Petrenko's upcoming project at Isi Camp, and driller Mike Jayred and engineer/driller Josh Goetz were PQed. Jayred and Goetz subsequently deployed on May 11.
IDDO also prepared for a few upcoming hand auger projects in Greenland. Kits were packed and shipped for PI Sarah Das, who used one of IDDO's new 3-Inch hand auger kits to drill shallow cores at one site on Disko Island and at two sites on the Nussuaq Peninsula in late April. A hand auger and Sidewinder kit were packed and shipped for PI Erich Osterberg, who plans to drill cores up to 40 meters depth outside of Thule airbase in late May. Initial preparations were also made for the packing and shipping of hand auger and Sidewinder equipment for PI David Noone's project at Summit Station. Noone's field work in late June and early July will mark the fourth and final year of his four-year project. One additional hand auger project was completed early in the quarter for PI Mike McKay at Bowling Green State University. McKay utilized a new IDDO hand auger to collect river and lake ice samples in the Midwest US as well as in Canada. His project, funded through the NSF Division of Environmental Biology, is scheduled to continue into 2016.
In addition to field season planning and cargo preparation, IDDO also completed proposal support estimates for thirteen separate science projects for the 2014 NSF Antarctic Proposal solicitation. Letters of Support and Cost Estimates were provided to PIs for inclusion in their proposal submissions.
