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

Four drillers, one welder, and a drill manager from the University of Nebraska, Lincoln (UNL) will deploy to McMurdo in mid October 2017 to finish repairs and maintenance to the WISSARD Hot Water drill to prepare for drilling in 2018-19 for the Subglacial Antarctic Lakes Scientific Acces (SALSA, C-533-M) project. The majority of their work will focus on repairs for a high pressure pump unit (HPU-1), the hose reel container, and testing of the operating system, but they will also give attention to general repairs, maintenance and packing. The UNL team will do most of the repairs but will receicve assistance from skilled Antarctic Support Contractor (ASC) generator technicians and electricians. They will conduct the repairs 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 early December.
