Description

The Subglacial Antarctic Lakes Scientific Access (SALSA) hot-water drill will be operated at Subglacial Lake Mercer (SLM) this season. The University of Nebraska, Lincoln drill team will complete preparation, configuration, and loading of the drill onto the launch and recovery system (LARS) deck for transportation to the drilling site at SLM. The team will drill one main hole for science operations and a secondary access hole for collection of basal ice and instrument installation.


Field Season Overview

Three drillers and a drill manager from the University of Nebraska, Lincoln will deploy to McMurdo in early November, 2016 to repair and perform general maintenance on the WISSARD drill to prepare it for use in the Subglacial Antarctic Lakes Scientific Access (SALSA) project in 2017-18. The majority of the repairs will be to the high-pressure pump units (HPU-1 and HPU-2), and the filtration unit, but they will also do general repairs and maintenance. Most of the repairs will be done by the UNL team but some assistance from McMurdo-based skilled tradesmen (especially a welder) may be required. The repairs will be conducted in a near-station location to which the team will be able to drive. There also is a general downsizing that will take place to the drill so some forklift support will be requested. The work should be completed and the drill team headed off station by the 9th of January.
