A 22 January 2015 photo of the SPICE drill site, newly constructed in November/December 2014 (PR/APL). The two-year project is a multi-institutional effort--the consortium includes UC-I (Eric Saltzman and Murat Aydin, PI's). Other participants are from UNH, and UW. The project uses an "intermediate-depth drill" developed by IDDO...(more information about the drill). | |
The first members of the drilling team reached Pole on 8 November...they worked to dig out modules that would be used at the site, and prioritized cargo delivery. The science team started to arrive a week later. By the end of November, final engineering approvals were given for the drill site facilities, and erection proceeded apace. | |
The drill itself has a tilting support structure, which allows it to be tilted into the vertical position, down into the drilling trench seen in the above diagram, for the actual drilling operations. After bringing up a core, it can be tilted into the horizontal position for core removal and processing. Drilling preparations, tweaking of the storage trench design, and shallow hand auger core collection continued through 7 December...and actual drilling began on Monday 8 December...shortly afterward the main control console was fried. Dealing with that took until Friday when a workaround was developed. Difficulties continued into the following week, when (after recovering 160m of core) it was decided to end dry drilling and start using the Estisol drilling fluid. | |

The exposed cutting head and core barrel, with some very sharp edges. Different barrels/heads were used for drilling with or without drilling fluid. The green cylinder at right is the fiberglass epoxy wound cover tube visible in other photos (JG). | |

The drilling season concluded on the morning of Saturday 24 January 2015, at a depth of 736m/2,415 feet. Many ice cores were shipped north, with 150m or cores left in the storage trench for the winter. The last remaining members of the team departed Pole on 30 January.
